How to upload a file in Sharepoint 2010 using c# console

Is there a way to automatically upload a file in Sharepoint 2010 using c#? We have no administrative control on the Sharepoint server. We just need to write a program that will upload a local file to a designated sharepoint library. The program will run on our server which in no way affiliated with the sharepoint server.

The following options could be considered for uploading the file into SharePoint via CSOM.

Prerequisites: SharePoint Foundation 2010 Client Object Model Redistributable

Using FileCollection.Add method

FileCollection.Add method adds a file to the collection based on provided file creation information

public static void UploadFile(ClientContext context, string uploadFolderUrl, string uploadFilePath)
{
    var fileCreationInfo = new FileCreationInformation
    {
        Content = System.IO.File.ReadAllBytes(uploadFilePath),
        Overwrite = true,
        Url = Path.GetFileName(uploadFilePath)
    };
    var targetFolder = context.Web.GetFolderByServerRelativeUrl(uploadFolderUrl);
    var uploadFile = targetFolder.Files.Add(fileCreationInfo);
    context.Load(uploadFile);
    context.ExecuteQuery();
}

Usage

using (var ctx = new ClientContext(webUri))
{
     ctx.Credentials = credentials;
     UploadFile(ctx,"Documents/Orders",@"c:\upload\user guide.docx");
}

where Orders is a folder in Documents library

According to Uploading files using Client Object Model in SharePoint 2010:

The above code might fail throwing a (400) Bad Request error depending on the file size.

Using File.SaveBinaryDirect method

File.SaveBinaryDirect method - uploads the specified file to a SharePoint site without requiring an ExecuteQuery() method call.

public static void UploadFile(ClientContext context, string folderUrl, string uploadFilePath)
{
    using (var fs = new FileStream(uploadFilePath, FileMode.Open))
    {
        var fileName = Path.GetFileName(uploadFilePath);
        var fileUrl = String.Format("{0}/{1}", folderUrl, fileName);
        Microsoft.SharePoint.Client.File.SaveBinaryDirect(context, fileUrl, fs, true);
    }
}

Usage

using (var ctx = new ClientContext(webUri))
{
     ctx.Credentials = credentials;
     UploadFile(ctx,"/News/Documents/Orders",@"c:\upload\user guide.docx");
}

where Orders is a folder in Documents library located on web site News.

FolderUrl format: /<web url>/<list url>/<folder url>
