Which is fast comparison: Convert.ToInt32(stringValue)==intValue or stringValue==intValue.ToString()

Question

While developing my application i came across some comparison stuff here was it:

    string str = \"12345\";
    int j = 12345;
    if (str == j.ToString())
             


        

Answer 1

Okay, i further move one step ahead and test in this way:

    int j = 123;
    for (var i = 0; i < iterationCount; i++)
    {
        j.ToString();
    }

second one: string str = "123";

        for (var i = 0; i < iterationCount; i++)
        {
            Convert.ToInt32(str);
        }

In this case i found every time second one is performing a little better. In my case the number would be like 100000 only and not in the form of 100,000. Your comments on this test that i did in this post ??
