我想获得一些文件夹 - 子文件。我在列表中包含所有文件夹SharePoint ID。我的代码正在运行,但它的性能非常差,因为有很多context.ExecuteQuery;
我想通过Caml查询来实现它。
using (var context = new ClientContext("http://xxx/haberlesme/"))
{
var web = context.Web;
var list = context.Web.Lists.GetById(new Guid(target));
int[] siraliIdArray;
//siraliIdArray = loadSharePointIDList(); think like this
for (var j = 0; j < siraliIdArray.Count; j++)
{
var folderName = listItemCollection[j]["Title"].ToString();//Folder Name
var currentFolder = web.GetFolderByServerRelativeUrl("/haberlesme/Notice/" + folderName);
var currentFiles = currentFolder.Files;
context.Load(currentFiles);
//I don't want to execute for n folder n times. I want to execute n folder 1 time.
context.ExecuteQuery();
var ek = new LDTOTebligEk();
//I don't want to add one - one
foreach (var file1 in currentFiles)
{
ek.DokumanPath = urlPrefix + folderName + "/" + file1.Name;
ek.DokumanAd = file1.Name;
ekler.Add(ek);
}
}
}

由于CSOM API支持Request Batching:
CSOM编程模型是围绕请求批处理构建的。当你 使用CSOM,您可以执行一系列数据操作
ClientContext
对象。这些操作将提交给服务器 致电ClientContext.BeginExecuteQuery
时的一个请求 方法
您可以重构您的代码,如下所示:
var folders = new Dictionary<string,Microsoft.SharePoint.Client.Folder>();
var folderNames = new[] {"Orders","Requests"};
foreach (var folderName in folderNames)
{
var folderKey = string.Format("/Shared Documents/{0}", folderName);
folders[folderKey] = context.Web.GetFolderByServerRelativeUrl(folderKey);
context.Load(folders[folderKey],f => f.Files);
}
context.ExecuteQuery(); //execute request only once
//print all files
var allFiles = folders.SelectMany(folder => folder.Value.Files);
foreach (var file in allFiles)
{
Console.WriteLine(file.Name);
}

使用Caml查询:
Microsoft.SharePoint.Client.List list = clientContext.Web.Lists.GetByTitle("Main Folder");
Microsoft.SharePoint.Client.CamlQuery caml = new Microsoft.SharePoint.Client.CamlQuery();
caml.ViewXml = @"<View><Query><Where><Eq><FieldRef Name='FileLeafRef'/><Value Type='Folder'>SubFolderName</Value></Eq></Where></Query></View>";
caml.FolderServerRelativeUrl = " This line should be added if the main folder is not in the site layer";
Microsoft.SharePoint.Client.ListItemCollection items = list.GetItems(caml);
clientContext.Load(items);
//Get your folder using items[0]
