Supported by Silverlight for Windows PhoneSupported by Xbox 360StringA sealed class type representing Unicode character strings.

Call the GetTypeCode method on classes that implement the IConvertible interface to obtain the type code for an instance of that class.

Otherwise, call an object's GetType method to obtain its Type object, then call the Type object's GetTypeCode method to obtain the object's type code.

The following code example demonstrates how the TypeCode enumeration can be used. In a decision block inside the WriteObjectInfo method, the TypeCode of an Object parameter is examined, and an appropriate message is displayed.


Sub WriteObjectInfo(ByVal outputBlock As System.Windows.Controls.TextBlock, ByVal testObject As Object)
   Dim typeCode As TypeCode = Type.GetTypeCode(testObject.GetType())

   Select Case typeCode
      Case typeCode.Boolean
         outputBlock.Text += String.Format("Boolean: {0}", testObject) & vbCrLf

      Case typeCode.Double
         outputBlock.Text += String.Format("Double: {0}", testObject) & vbCrLf

      Case Else
         outputBlock.Text += String.Format("{0}: {1}", typeCode.ToString(), testObject) & vbCrLf
   End Select
End Sub
