Title says it all...

But here's an example:

Dim desiredType as Type
if IsNumeric(desiredType) then ...

EDIT: I only know the Type, not the Value as a string.

Ok, so unfortunately I have to cycle through the TypeCode.

But this is a nice way to do it:

 if ((desiredType.IsArray))
      return 0;

 switch (Type.GetTypeCode(desiredType))
 {
      case 3:
      case 6:
      case 7:
      case 9:
      case 11:
      case 13:
      case 14:
      case 15:
          return 1;
 }
 ;return 0;
