As a follow up to my recent post showing how to create or overwrite a document using the CSOM, I’m now going to show how to upload a file containing large amounts of data. To see the original post, click here.

public void SaveFile(Microsoft.SharePoint.Client.ClientContext context, string folderRelativeUrl, string relativeItemUrl, byte[] fileData) { var fci = new FileCreationInformation { Url = relativeItemUrl, Content = fileData, Overwrite = true }; Microsoft.SharePoint.Client.Folder folder = context.Web.GetFolderByServerRelativeUrl(folderRelativeUrl); Microsoft.SharePoint.Client.FileCollection files = folder.Files; Microsoft.SharePoint.Client.File file = files.Add(fci); context.Load(files); context.Load(file); context.ExecuteQuery(); } |
