Generic String.Parse Extension Method

How can I create generic parse method to convert string to number or date?

After reading this post about missing parses method for nullable integer and possible implementation. I want to share my version of parse method with generic touch.

Here's my parser class

				using System;
using System.ComponentModel;

public static class Parser {

     public static T Parse<T>(this string value) {
        // Get default value for type so if string
        // is empty then we can return default value.
        T result = default(T);

        if (!string.IsNullOrEmpty(value)) {
          // we are not going to handle exception here
          // if you need SafeParse then you should create
          // another method specially for that.
          TypeConverter tc = TypeDescriptor.GetConverter(typeof(T));
          result = (T)tc.ConvertFrom(value);
        }

        return result;
    }
}

// regular parsing
int i = "123".Parse<int>(); 
int? inull = "123".Parse<int?>(); 
DateTime d = "01/12/2008".Parse<DateTime>(); 
DateTime? dn = "01/12/2008".Parse<DateTime?>();

// null values
string sample = null;
int? k = sample.Parse<int?>(); // returns null
int l = sample.Parse<int>();   // returns 0
DateTime dd = sample.Parse<DateTime>(); // returns 01/01/0001
DateTime? ddn = sample.Parse<DateTime?>(); // returns null
