How to Upload a Document with Properties using SharePoint 2010 Client Object Model

Today I came across the need to be able to upload documents to a SharePoint list.  Not so bad, I have done this before, but this time I also need to populate some custom metadata about the document.  After a lot of looking, searching and exceptions I finally found the answer and here it is.

Add References to Microsoft.SharePoint.Client Library

Install-Package Microsoft.SharePoint.Client

Define a form

The important part I always forget is the enctype=”multipart/form-data”.

 1: <form id="formUpload" method="POST" enctype="multipart/form-data ">
 2:     <input type="file" id="fileUpload" name="fileUpload" runat="server"/>
 3:     <input type="submit" value="upload" 
 4:         OnServerClick="btnUploadTheFile_Click" runat="server"/>
 5: </form>

The btnUploadTheFile_Click Handler

 1: private void UpLoadToSharePoint()
 2:  {
 3:     var fileName = Path.GetFileName(fileUpload.PostedFile.FileName);
 4:     var fileStream = new FileStream(fileUpload.PostedFile.FileName, FileMode.Open);
 5:     var byteStream = new byte[fileStream.Length];
 6:     fileStream.Read(byteStream, 0, byteStream.Length);
 7:  
 8:     var serverRelativeUrl = "/MySite/MyDocumentLibrary/" + fileName;
 9:  
 10:     var fileCreationInformation = new FileCreationInformation
 11:     {
 12:         Content = byteStream, 
 13:         Overwrite = true, 
 14:         Url = serverRelativeUrl
 15:     };
 16:  
 17:     var file = _sharePointList.RootFolder.Files.Add(fileCreationInformation);
 18:     file.ListItemAllFields["Column 1"] = "Value 1";
 19:     file.ListItemAllFields["Column 2"] = "Value 2";
 20:     file.ListItemAllFields.Update();
 21:     
 22:     _sharePointContext.ExecuteQuery();
 23: }

Summary

This simple example shows how easy it is to upload a file to a SharePoint document list and provide additional column information.
