Question

我一直收到这个错误：

Item does not exist. It may have been deleted by another user.

我不知道我的装配是否有问题，但它在这里打破了：

Line 227:
Line 228:
Line 229:                    SPListItem item = list.GetItemById(Int32.Parse(projectApprovalId));
Line 230:                    SPFolder itemFolder = item.Folder;
Line 231:

我认为它与我的程序集有关，就像它可能无法正确导入sharepoint一样。

我在layouts文件夹中使用.ashx文件，它是一个ihttphandler。这是我的文件的样子：

   <%@ Assembly Name="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>
    <%@ WebHandler Language="C#" Class="jQueryUploadTest.Upload" %>

    namespace jQueryUploadTest {



public class Upload : IHttpHandler {
        public class FilesStatus
        {/*
            public string thumbnail_url { get; set; }
            public string name { get; set; }
            public string url { get; set; }
            public int size { get; set; }
            public string type { get; set; }
            public string delete_url { get; set; }
            public string delete_type { get; set; }
            public string error { get; set; }
            public string progress { get; set; }
           */

            private string m_thumbnail_url;
            private string m_name;
            private string m_url;
            private int m_size;
            private string m_type;
            private string m_delete_url;
    .........

这是堆栈跟踪：

破解的代码：

private void ListCurrentFiles (HttpContext context) {
            List<FilesStatus> files = new List<FilesStatus>();
            SPFileCollection fileCollection;
            //using(SPSite siteCollection = new SPSite()){
            using (SPWeb site = SPContext.Current.Web)
                {
                    string projectApprovalId = string.Empty;
                    if (System.Web.HttpContext.Current.Request.QueryString["ProjectApprovalId"] != null)
                    {
                        projectApprovalId = System.Web.HttpContext.Current.Request.QueryString["ProjectApprovalId"].ToString();
                    }
                    SPList list = site.Lists.TryGetList(GetResourcePropertyValue("KEY_CLM_DocumentLibrary_Name"));


                    SPListItem item = list.GetItemById(Int32.Parse(projectApprovalId));
                    SPFolder itemFolder = item.Folder;


                    fileCollection = itemFolder.Files;

Answer 1

什么是projectApprovalId？导致错误是因为该列表中没有任何项ID具有projectApprovalId的值{。}}。

物品不存在。它可能已被其他用户删除
