我正在使用可视化Web部件.

I am using visual web part.

我正在尝试以编程方式获取子文件夹中上载的所有文件，并在超链接中显示每个文件.我已经尝试了以下代码，但不确定如何检索文件并将其添加到超链接.超链接是在aspx中创建的.

I am trying to fetch all the files uploaded in a sub folder programmatically and show each of the files in a hyperlink . I have tried the below code, but not sure, how to retrieve the file and add it to a hyperlink. The hyperlink is created in aspx.

private void ShowAttachmentLinks(SPWeb osubWeb) { SPQuery query = new SPQuery(); string foldername = "Shared Documents"; SPDocumentLibrary docLib = osubWeb.Lists[foldername] as SPDocumentLibrary; string SubFolderUrl = osubWeb.ServerRelativeUrl + "/" + foldername + "abc" + "/" + bcd; SPFolder folder = osubWeb.GetFolder(SubFolderUrl); query.Folder = folder; query.Query="<View Scope=\"RecursiveAll\">" + "<Where>" + "<Eq>" + "<FieldRef Name=\"FileDirRef\" />" + "<Value Type=\"Text\">" + folder +"</Value>" + "</Eq>" + "</Where>" + "</View>";

以上代码正确吗?如何检索每个文件?

Is the above code correct? How to retrieve each of the files?

谢谢

您好，Venkat，

Hi Venkat,

尝试以下代码:

public string CreateListUsingCAMLAttachments(string siteURL,string ID) { List list; string temp = null; IEnumerable<Microsoft.SharePoint.Client.ListItem> listItems; using (ClientContext context = new ClientContext(siteURL)) { list = context.Web.Lists.GetByTitle("CDP Tools"); CamlQuery cq = new CamlQuery(); cq.ViewXml = @"<View><Query><Where><Eq><FieldRef Name='ID' /><Value Type='Text'>"+ID+"</Value></Eq></Where></Query><ViewFields><FieldRef Name='Attachments' /></ViewFields></View>"; listItems = context.LoadQuery(list.GetItems(cq)); context.Load(list.RootFolder); context.Load(list.RootFolder.Files); context.Load(list.RootFolder.Folders); context.ExecuteQuery(); foreach (Folder f in list.RootFolder.Folders) { context.Load(f.Folders); context.ExecuteQuery(); foreach (Folder f1 in f.Folders) { if (f1.Name == ID) { context.Load(f1.Files); context.ExecuteQuery(); foreach (File file1 in f1.Files) { ListBox1.Items.Add(file1.Name); temp = file1.Name; } } else { // } } } } return temp; }
