Examples

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 written to the console.

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

static void WriteObjectInfo(System.Windows.Controls.TextBlock outputBlock, object testObject)
{
   TypeCode typeCode = Type.GetTypeCode(testObject.GetType());

   switch (typeCode)
   {
      case TypeCode.Boolean:
         outputBlock.Text += String.Format("Boolean: {0}", testObject) + "\n";
         break;

      case TypeCode.Double:
         outputBlock.Text += String.Format("Double: {0}", testObject) + "\n";
         break;

      default:
         outputBlock.Text += String.Format("{0}: {1}", typeCode.ToString(), testObject) + "\n";
         break;
   }
}
