To upload any content on server...what to use?

Answer 1

You don't need to use any fancy "web service" technology to upload data from a client application to a server. You can create a simple ASP.NET Web handler and save the input file from the request body:

public class FileUploader : IHttpHandler
{
    public void ProcessRequest(HttpContext context)
    {
       string fileName = context.Request.QueryString["FileName"];
       byte[] fileData = context.Request.BinaryRead(context.Request.ContentLength);
       string path = ...; // decide where you want to save the file
       File.WriteAllBytes(path, fileData);
    }

    public bool IsReusable
    {
        get { return false; }
    }
}

From the client app, you'd use WebClient.UploadFile method:

using (var client = new WebClient()) {
    client.QueryString["FileName"] = fileName;
    client.UploadData(url, inputFileData); 
}

This approach eliminates the overhead of protocols like SOAP and posts the file directly in the HTTP request body.

If you really want to up-/download *files you should maybe take the File Transfer Protocol (FTP).

• FtpWebRequest
