How to determine size of the C# Object

I define my object as follows: 

public class A
{
    public object Result
    {
        get
        {
            return result;
        }
        set
        {
            result = value;
        }
    }
}

and then i am storing some string value inside it as :

A.Result=stringArray;

here stringArray has 5 string values. now i want to use that object somewhere else and would like to know the length of string value inside this object. How?

If you're just looking for the length of Result if it's a string then you can do the following.

var s = Result as string;
return s == null ? 0 : s.Length;

Based on your comment while typing all this up. It sounds like the following is what you actually want

If it's array:

var array = Result as string[];
return array == null ? 0 : array.Length;

or if you want the total length of all the items in the array:

var array = Result as string[];
var totalLength = 0;
foreach(var s in array)
{
    totalLength += s.Length;
}

If you want to know the size in bytes then you need to know the encoding. 

var array = Result as string[];
var totalSize = 0;
foreach(var s in array)
{
    //You'll need to know the proper encoding. By default C# strings are Unicode.
    totalSize += Encoding.ASCII.GetBytes(s).Length;
}

You can get the Length of the object by converting it into array of string.

For Example:

static void Main(string[] args) {

        A.Result = new string[] { "il","i","sam","sa","uo"}; //represent as stringArray

        string[] array = A.Result as string[];

        Console.WriteLine(array.Length);

        Console.Read();
}

Your object is Invalid so I rewrite:

public class A
{
    public static object Result { get; set; } //I change it to static so we can use A.Result;
}

var array  = A.Result as string[];

if (array != null)
{
    Console.WriteLine(array.Length);
}
