typeof() to check for Numeric values

what is the easiest way to check if a typeof() is mathematically usable(numeric).

do i need to use the TryParse method or check it by this:

if (!(DC.DataType == typeof(int) || DC.DataType == typeof(double) || DC.DataType == typeof(long) || DC.DataType == typeof(short) || DC.DataType == typeof(float)))
     {
           MessageBox.Show("Non decimal data cant be calculated");
           return;
     }

if there is a more easy way to achieve this, your free to suggest
