which one is faster data types in .net or data types in c#? : <p>Hi to all first of all i am sorry because my first language is not english
I want understand which one is faster C# data types or .net data types
i try to understand by below code and i think .net data types is faster(is this correct?)
i test this code both with x86 and x64 platform</p>

<pre><code>            SW.Start();
            for (Int32 i = 0; i &lt; 99999; i++)
            {
                for (Int32 j = 0; j &lt; 999; j++)
                {
                    Int32 a = 37;
                    Int32 b = 37;
                    Double c = Math.Pow(a, b);
                    String d = "abcde";
                    String e = "abcde";
                    String f = d + e;
                }


            }
            Console.WriteLine(SW.Elapsed.TotalMilliseconds);
            SW.Stop();
            Console.ReadKey();
</code></pre>

<p>and my second code</p>

<pre><code>
  Stopwatch SW = new Stopwatch();
            SW.Start();
            for (int i = 0; i &lt; 99999; i++)
            {
                for (int j = 0; j &lt; 999; j++)
                {
                    int a = 37;
                    int b = 37;
                    double c = Math.Pow(a, b);
                    string d = "abcde";
                    string e = "abcde";
                    string f = d + e;
                }


            }
            Console.WriteLine(SW.Elapsed.TotalMilliseconds);
            SW.Stop();
            Console.ReadKey();
</code></pre>

<p>thank a lot</p>
