Question

I have a web application, and in the DAL file I have some methods. The methods get results by calling an API. For example:

public string GetUserName(int userID)
{
     HttpWebRequest GETRequest = (HttpWebRequest)WebRequest.Create(url);
     GETRequest.Method = "GET";

     HttpWebResponse GETResponse = (HttpWebResponse)GETRequest.GetResponse();
     Stream GETResponseStream = GETResponse.GetResponseStream();
     StreamReader srResponse = new StreamReader(GETResponseStream);

     return srResponse.ReadToEnd();     
}

My requirement is that I need to execute these methods via command the line and show the result. I do not understand how to do this; please suggest a way to proceed.

Well, you need to parse the command line arguments. Let’s say we define our command line format like this: yourprogram.exe function_name paramValue, then we need to do the following:

public static void Main(string[] args)
{
    switch(args[0])
    {
        case "GetUserName" :
        Console.WriteLine(GetUserName(args[1]));
        break;
        case "YourOtherMethod":
        //...
        break;
    }
}

then, you would execute yourprogram.exe GetUserName 5 in the console.
