Well, let's assume your xml is in a file and you are writing a C# DotNET console application.

You can run this application from a command line and pass the filename as the first argument.

The program should read the xml as a string rather than load it into an XDocument since you want to post the xml to a destination url.

The program would then instantiate a WebClient and call the UploadString() method passing the url to the server and the xml string. This will do the post.

Also, there is an UploadFile() method that may make this even easier since it will read the file for you.

Hi Gary,

Thanks for your response.

Are there any sample pieces of code that I can use & then plugin my XML data using the C# DotNET console application ?

I'm not an expert in C# ?

Thanks again.

Here is a simple program that uses the filename specified in the 1st argument. You can add error checking like verify there actually is an arg[0] and that the file exists and that the UploadFile() does not trap, etc.

namespace ConsoleApplication
{
    class Program
    {
        static void Main(string[] args)
        {
            var xmlFile = args[0]; // File to post
            var webClient = new System.Net.WebClient();
            webClient.UploadFile("http://www.someserver.com/", "POST", xmlFile);
        }
    }
}
