To run this example, see Building Examples That Use a Demo Method and a TextBlock Control.

Imports System.Reflection

Public Class Example
   Public myField As String = "A public field"

   Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
      Dim myObject As New Example()

      ' Get the Type and FieldInfo.
      Dim myType1 As Type = GetType(Example)
      Dim myFieldInfo As FieldInfo = myType1.GetField("myField", _
         BindingFlags.Public Or BindingFlags.Instance)

      ' Display the name, field and the PInvokeImpl attribute for the field.
      outputBlock.Text &= String.Format("{0}Name of class: {1}", _
                    ControlChars.NewLine, myType1.FullName) 
      outputBlock.Text &= String.Format("{0}Value of field: {1}", _
                    ControlChars.NewLine, myFieldInfo.GetValue(myObject)) 
      outputBlock.Text &= String.Format("{0}IsPinvokeImpl: {1}", _
                    ControlChars.NewLine, myFieldInfo.IsPinvokeImpl) 
   End Sub
End Class

   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      Example myObject = new Example();

      // Get the Type and FieldInfo.
      Type myType1 = typeof(Example);
      FieldInfo myFieldInfo = myType1.GetField("myField",
          BindingFlags.Public | BindingFlags.Instance);

      // Display the name, field and the PInvokeImpl attribute for the field.
      outputBlock.Text += String.Format("\n Name of class: {0}", myType1.FullName);
      outputBlock.Text += String.Format("\n Value of field: {0}", myFieldInfo.GetValue(myObject));
      outputBlock.Text += String.Format("\n IsPinvokeImpl: {0}",
          myFieldInfo.IsPinvokeImpl);
   }
