GetCommandLineArgs() method

Question

Hi guys,
Can anyone tell me what is the use of GetCommandLineArgs() method in C#.

Answer 1

Hi akash,

GetCommandLineArgs method returns a string array containing the command-line arguments for the current process. Although you can receive command line arguments in the Main entry point in the C# language, the GetCommandLineArgs method can be used anywhere.

For example,

using System;

class Program

{

    static void Main(string[] args)

    {

// Args does not contain the program path.

Console.WriteLine(string.Join(",", args));

// GetCommandLineArgs contains the program path as the first element.

string[] array = Environment.GetCommandLineArgs();

Console.WriteLine(string.Join(",", array));

    }

}

The same thing can be done through the array command arquments.

using System;

class Program

{

    static void Main(string[] args)

    {

if (args == null)

{

   Console.WriteLine("args is null"); // Check for null array

}

else

{

   Console.Write("args length is ");

   Console.WriteLine(args.Length); // Write array length

   for (int i = 0; i < args.Length; i++) // Loop through array

   {

string argument = args[i];

Console.Write("args index ");

Console.Write(i); // Write index

Console.Write(" is [");

Console.Write(argument); // Write string

Console.WriteLine("]");

   }

}

Console.ReadLine();

    }

}

Notice that the string array returned by the Environment.GetCommandLineArgs() method differs from the one returned by the args parameter to the Main() method.

The former returns the file name of the executing program as the first element of the array. The latter does not.

GetCommandLineArgs() is used when you want to retrieve the program's command line arguments from somewhere other than the Main() method or to retrieve the program's file name. There are, however, other ways to do the second of these operations.

Hi,

With GetCommandLineArgs() method, the command line arguments can be accessed.
The value returned is an array of strings. It is a method of the System.Environment class. See the code example below:
C# Example
public static int Main(string[] args)
{
 string[] strArgs = System.Environment.GetCommandLineArgs();
 Console.WriteLine("Arguments {0}", strArgs[0]);
}



Thanks.
