Sharepoint -How to Move/Copy folder to another location Using SOAP API copyIntoItems()

Question

I am trying to move/copy a folder from one location to another location it is giving me an error

Object reference not set to an instance of an object

but it is working fine with File.

I am using SOAP API copyIntoItems() function

copyService.copyIntoItems(sourceUrl, destinationUrl, fieldInformationCollection, fileContent, hld,result);

but in this API we compulsory need to pass file content(data blob) but I have an empty folder that I have to copy/move

Answer 1

You cannot copy folders from one location to another using Copy.CopyIntoItems - this method copies a document represented by a Byte array to one or more locations on a server. For more information, refer Copy.CopyIntoItems method.

A new utility class Microsoft.SharePoint.Client.MoveCopyUtil is available on the latest version of the O365 Microsoft.SharePoint.Client.dll

Microsoft.SharePoint.Client.MoveCopyUtil has the following functions:

public static void MoveFile(ClientRuntimeContext context, string srcUrl, string destUrl)
public static void CopyFile(ClientRuntimeContext context, string srcUrl, string destUrl)
public static void MoveFolder(ClientRuntimeContext context, string srcUrl, string destUrl)
public static void CopyFolder(ClientRuntimeContext context, string srcUrl, string destUrl)

for more information refer MoveCopyUtil.CopyFolderByPath method
