I need help with Sharepoint CSOM. I have used this

using Microsoft.SharePoint.Client;
//removed code
var context = new ClientContext(myURl);
var file = context.Web.GetFileByServerRelativeUrl(FileUrl);

var libraryFields = file.ListItemAllFields;

libraryFields["Title"] = "My title";

file.CheckIn(string.Empty, CheckinType.OverwriteCheckIn);


when I run the above code I get the following error:

The file "https://****.sharepoint.com/sites/myfile.tif" is checked out for editing by i:0#.f|membership|[email protected]

Can anyone please tell me what is going wrong in my code.

  • You can try to do a context.ExecuteQuery(); before file.CheckIn (but keep the last one as well) and see if that makes any difference Mar 30, 2020 at 11:17
  • context.load(file) before you checout Mar 30, 2020 at 11:49

Try to add the below code, before executing the context.ExecuteQuery() publish and load the file and also check for it is not checked out.

if (file.CheckOutType != CheckOutType.None)
       file.CheckIn("Check in comment": "", checkInType: CheckinType.MajorCheckIn);
            file.Publish(comment: "");
