Hello

I successfully got metadata from Sharepoint files to display and used the built-in MoveCopyOptions to move files from one SharePoint folder to another.

I now want to be able to add files programmatically to SharePoint and use the information inputted from a form by the user to populate the metadata.

The file is copied from the user's local drive to the share point folder however I am not able to update the metadata. Could someone let me know if they can spot what is wrong?

Thank you in advance.

What I have tried:

public bool CopyLocalFileToSP(string localPath, string fileName, string caseNumber, string userName, string comment)
{
    try
    {
        using (var clientContext = new ClientContext(_helper.WebRoot()))
        {
            var web = clientContext.Web;

            clientContext.Load(web, website => website.ServerRelativeUrl);
            clientContext.ExecuteQuery();

            var serverRelativeURL = web.ServerRelativeUrl + "/" + "Documents/" + caseNumber.Substring(0, caseNumber.IndexOf("-")) + "/" + caseNumber + "/" + fileName;

            using (FileStream fs = new FileStream(Path.Combine(localPath, fileName), FileMode.OpenOrCreate))
            {
                Microsoft.SharePoint.Client.File.SaveBinaryDirect(clientContext, serverRelativeURL, fs, true);
            }

            Microsoft.SharePoint.Client.File newFile = web.GetFileByServerRelativeUrl(serverRelativeURL);
            clientContext.Load(newFile);
            clientContext.ExecuteQuery();


            newFile.CheckOut();

            ListItem item = newFile.ListItemAllFields;


            item["FileLeafRef"] = fileName;
            item["Comment1"] = comment;
            item["DocumentDate"] = DateTime.Now;
            item["Created"] = DateTime.Now;
            item["Modified_x0020_By"] = userName;
            item["DocumentType"] = "Member";
            item.Update();

            newFile.CheckIn(string.Empty, CheckinType.OverwriteCheckIn);
        }

        return true;
    }
    catch <pre><pre lang="C#">

{
return false;
}
}
