How to Overwrite SharePoint's Created Date after Doing a SaveBinaryDirect?

sp13test 281

using (var ctx = new ClientContext(DataSharepointSite))
    {
        ctx.AuthenticationMode = ClientAuthenticationMode.Default;
        ctx.Credentials = GetCreds();
        using (FileStream fs = new FileStream(localFile, FileMode.Open))
        {
            Microsoft.SharePoint.Client.File.SaveBinaryDirect(ctx, sharepointFile, fs, true);
        }

        //****************
        // Now somehow set Modified Date to local File's Modified Date
        //****************
        var file = ctx.Web.GetFileByServerRelativeUrl(sharepointFile);
        ListItem lstItem = file.ListItemAllFields;
        ctx.Load(lstItem);
        ctx.ExecuteQuery();
        lstItem["CreatedDate"] = System.IO.File.GetCreationTime(localFile).ToUniversalTime();
        lstItem.Update();
        ctx.ExecuteQuery();
    }

But I can't set into item, is there any wrong in the code ?

Hi @sp13test ,

Modify a bit in the code:

    var file = ctx.Web.GetFileByServerRelativeUrl(sharepointFile);  
    ListItem lstItem = file.ListItemAllFields;  
    ctx.Load(lstItem);  
    ctx.ExecuteQuery();  
    lstItem["Created"] = System.IO.File.GetCreationTime(localFile).ToShortDateString();  
    lstItem.Update();  
    ctx.ExecuteQuery();

Thanks
Best Regards
