Question

我正在使用此代码将凭据传递给Sharepoint站点Web服务，

var client = new SiteWebReference.Lists();
System.Net.NetworkCredential passCredentials = new System.Net.NetworkCredential("username", "password", "domain");
client.Credentials = passCredentials;

我正在使用此代码来提取条目的Sharepoints列表，

private IEnumerable<TaskEntry> LoadTasks()
{
  var data = GetListItems("Tasks");
  var result = XElement.Parse(data.OuterXml);
  XNamespace z = "#RowsetSchema";
  var taskItems = from r in result.Descendants(z + "row")
                  select new TaskEntry
                            {
                               TaskName = r.Attribute("ows_LinkTitle").Value,
                               DueDate = r.Attribute("ows_DueDate") != null ? r.Attribute("ows_DueDate").Value : string.Empty,
                               AssignedTo = r.Attribute("ows_AssignedTo") != null ? r.Attribute("ows_AssignedTo").Value : string.Empty,
                            };
   return taskItems;
}

我一直在寻找有关向现有List添加新条目的信息，这意味着我想在“任务列表”中添加一个新条目。我得出的结论是代码应该可行，

public void updateListItemsWS()
{
   var client = new SPWebservices.Lists();
   System.Net.NetworkCredential passCredentials = new System.Net.NetworkCredential("username", "password", "domain");
   client.Credentials = passCredentials;


   System.Xml.XmlDocument xmlDoc = new System.Xml.XmlDocument();
   System.Xml.XmlElement elBatch = xmlDoc.CreateElement("Batch");

   elBatch.SetAttribute("OnError", "Continue");
   elBatch.SetAttribute("ListVersion", "1");

   string strBatch =   "<Method ID='1' Cmd='New'>" +
                       "<Field Name='ows_Client'>Miami Coalition of Partners</Field>" +
                       "<Field Name='ows_Title'>TestingApplication</Field>" +
                       "<Field Name='ows_Task_x0020_Type'>Support</Field>" +
                       "<Field Name='ows_Priority'>1</Field>" +
                       "<Field Name='ows_Status'>Assigned</Field>" +
                       "<Field Name='ows_AssignedTo'>57;#Sandro Perez</Field>" +
                       "<Field Name='ows_Owner'>57;#Sandro Perez</Field>" +
                       "<Field Name='ows_Body'>Testing my application</Field>" +
                       "<Field Name='ows_DueDate'>2014-04-21 00:00:00</Field>" +
                       "<Field Name='ows_Area'>2014-04-21 00:00:00</Field>" +
                       "<Field Name='ows_Group_x0020_Task'>WELS</Field>" +
                       "</Method>";

    elBatch.InnerXml = strBatch;

    client.UpdateListItems("Tasks", elBatch);
}

但是，当我检查Sharepoint网站上的“新条目”时，是否有任何建议？

这不是完整的XML，这是一小部分，

    <listitems
xmlns:s="uuid:BDC6E3F0-6DA3-11d1-A2A3-00AA00C14882"
xmlns:dt="uuid:C2F41010-65B3-11d1-A29F-00AA00C14882"
xmlns:rs="urn:schemas-microsoft-com:rowset"
xmlns:z="#RowsetSchema"
xmlns="http://schemas.microsoft.com/sharepoint/soap/">
<rs:data ItemCount="691">
    <z:row ows_Attachments="0" ows_ID="2108" ows_Task_x0020_Type="Issue" ows_Client="City University of New York" />
    </rs:data>

修改我在瓦迪姆的帮助下做了这些改变，

我现在有了这段代码，

public class ListsClient : IDisposable
    {
        public ListsClient(Uri webUri, ICredentials credentials)
        {
            _client = new Bluejeanware.MWELS.Lists();
            _client.Credentials = credentials;
            _client.Url = webUri + "/_vti_bin/Lists.asmx";
        }

        public ListsClient(Uri webUri)
        {
            _client = new Bluejeanware.MWELS.Lists();
            _client.Url = webUri + "/_vti_bin/Lists.asmx";
        }



        public XmlNode CreateListItem(string listName, Dictionary<string, string> propertyValues)
        {
            var payload = new XmlDocument();
            var updates = payload.CreateElement("Batch");
            updates.SetAttribute("OnError", "Continue");
            var method = payload.CreateElement("Method");
            method.SetAttribute("ID", "1");
            method.SetAttribute("Cmd", "New");
            foreach (var propertyValue in propertyValues)
            {
                var field = payload.CreateElement("Field");
                field.SetAttribute("Name", propertyValue.Key);
                field.InnerText = propertyValue.Value;
                method.AppendChild(field);
            }
            updates.AppendChild(method);
            return _client.UpdateListItems(listName, updates);
        }

        public ICredentials Credentials
        {
            get { return _client.Credentials; }
            set { _client.Credentials = value; }
        }

        public CookieContainer CookieContainer
        {
            get { return _client.CookieContainer; }
            set { _client.CookieContainer = value; }
        }


        public void Dispose()
        {
            _client.Dispose();
            GC.SuppressFinalize(this);
        }

        protected Bluejeanware.MWELS.Lists _client; 
    }

然后是CreateTask，

public void CreateTask(TaskEntry taskEntry)
    {
        var webUri = new Uri("http://sp.site.com/apps/msite/_vti_bin/Lists.asmx");
        var userName = "username";
        var password = "password";
        var domain = "domain";

        var client = new ListsClient(webUri);
        client.Credentials = new System.Net.NetworkCredential(userName, password, domain);

        var taskProperties = new Dictionary<string, string>();
        taskProperties["Client"] = taskEntry.Client;
        taskProperties["Title"] = taskEntry.Title;
        taskProperties["Task_x0020_Type"] = taskEntry.TaskType;
        taskProperties["Priority"] = taskEntry.Priority;
        taskProperties["Status"] = taskEntry.Status;
        taskProperties["AssignedTo"] = taskEntry.AssignedTo;
        taskProperties["Owner"] = taskEntry.Owner;
        taskProperties["Body"] = taskEntry.Body;
        taskProperties["DueDate"] = taskEntry.DueDate;
        taskProperties["Area"] = taskEntry.Area;
        taskProperties["Group_x0020_Task"] = taskEntry.GroupTask;
    }

然后我用一个按钮

调用CreateTask

private void Button_Click(object sender, RoutedEventArgs e)
    {
        CreateTask(new TaskEntry
        {
            Client = "VALUE",
            Title = "TestingApplication",
            TaskType = "VALUE",
            Priority = "1",
            Status = "Assigned",
            AssignedTo = "57;#Sandro Perez",
            Owner = "57;#Sandro Perez",
            Body = "Testing my application",
            DueDate = "2014-04-21 00:00:00",
            Area = "VALUE",
            GroupTask = "VALUE",
        });
    }

Answer 1

请输入任务列表的列表ID

client.UpdateListItems（strListID，elBatch）;

尝试使用StringBuilder或直接将值传递给elBatch.InnerXml =“your xml”

Answer 2

这是因为Name元素中的Field属性必须指定字段内部名称，例如Title（不是ows_Title ）。

您可以使用以下包装类来抽象SharePoint Web服务，并使创建列表项更容易：

using System;
using System.Collections.Generic;
using System.Net;
using System.Xml;

namespace App
{
    public class ListsClient : IDisposable
    {
        public ListsClient(Uri webUri, ICredentials credentials)
        {
            _client = new Lists.Lists();
            _client.Credentials = credentials;
            _client.Url = webUri + "/_vti_bin/Lists.asmx";
        }

        public ListsClient(Uri webUri)
        {
            _client = new Lists.Lists();
            _client.Url = webUri + "/_vti_bin/Lists.asmx";
        }


        /// <summary>
        /// Create a List Item 
        /// </summary>
        /// <param name="listName">List Name</param>
        /// <param name="propertyValues">List Item properties</param>
        /// <returns></returns>
        public XmlNode CreateListItem(string listName, Dictionary<string, string> propertyValues)
        {
            var payload = new XmlDocument();
            var updates = payload.CreateElement("Batch");
            updates.SetAttribute("OnError", "Continue");
            var method = payload.CreateElement("Method");
            method.SetAttribute("ID", "1");
            method.SetAttribute("Cmd", "New");
            foreach (var propertyValue in propertyValues)
            {
                var field = payload.CreateElement("Field");
                field.SetAttribute("Name", propertyValue.Key);
                field.InnerText = propertyValue.Value;
                method.AppendChild(field);
            }
            updates.AppendChild(method);
            return _client.UpdateListItems(listName, updates);
        }

        public ICredentials Credentials
        {
            get { return _client.Credentials; }
            set { _client.Credentials = value; }
        }

        public CookieContainer CookieContainer
        {
            get { return _client.CookieContainer; }
            set { _client.CookieContainer = value; }
        }


        public void Dispose()
        {
            _client.Dispose();
            GC.SuppressFinalize(this);
        }

        protected Lists.Lists _client;  //SharePoint Web Services Lists proxy
    }
}

然后你可以创建一个任务项，如下所示：

public void CreateTask(TaskEntry taskEntry)
{
     var webUri = new Uri("http://intranet.contoso.com/");
     var userName = "username";
     var password = "password";
     var domains = "domain";

     var client = new ListsClient(webUri);
     client.Credentials = new System.Net.NetworkCredential(userName, password, domain);

     var taskProperties = new Dictionary<string, string>();
     taskProperties["Title"] = taskEntry.TaskName;
     taskProperties["DueDate"] = taskEntry.DueDate;
     taskProperties["AssignedTo"] = taskEntry.AssignedTo;
     client.CreateListItem("Tasks", taskProperties);
}
