Satish,

If you have your method structure, do pass it to me so that I can give you more clear answer

What I understood is as below:

void somemethod(variablelength)
{

}

If so why do not you make the method to accept a int type and then use it. The calling method just have to calculate the length of the argument and pass the length as a parameter along with the arguments or you accept the argument and then find the length in your method.

Anyways, there is some confusion in understanding and so I would recommend you to send the pseudo code to understand your requirement better.

using string variable for length operation syntax for string.variable length();

You can also use the 'params' keyword to pass a variable number of arguments of the same type. Here's a simple example:

using System;

class Test
{
static void Main()
{
Print(1, 2, 3);
Print(4, 5, 6, 7, 8, 9);
Console.ReadKey();
}

static void Print(params int[] ia)
{
foreach(int i in ia) Console.Write("{0} ", i);
Console.WriteLine();
}
}

What do you mean by variable length? Any number of arguments or an argument of variable length?

If you mean any number of arguments, you can use collection as a parameter and process on each item.

Can you clarify a little bit more on this?
