MissingFieldException.Message Property

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Gets the text string showing the signature of the missing field, the class name, and the field name. This property is read-only.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public Overrides ReadOnly Property Message As String

public override string Message { get; }

Property Value

Type: System.String
The error message string.

Remarks

If the class name is not specified when the object is constructed, the default text string inherited from the base class is returned. This property overrides Message. The error message should be localized.

Examples

The following example demonstrates the Message property. This code example is part of a larger example provided for the MissingFieldException class.

Try
   ' Attempt to access a static AField field defined in the Example class.
   ' However, because the Example class does not define this field, 
   ' a MissingFieldException is thrown.
   GetType(Example).InvokeMember("AField", BindingFlags.Static Or BindingFlags.SetField, _
                              Nothing, Nothing, New [Object]() {5})
Catch e As MissingFieldException
   ' Show the user that the AField field cannot be accessed.
   outputBlock.Text += String.Format("Unable to access the AField field: {0}", e.Message) & vbCrLf
End Try

try
{
   // Attempt to access a static AField field defined in the Example class.
   // However, because the Example class does not define this field, 
   // a MissingFieldException is thrown.
   typeof(Example).InvokeMember("AField", BindingFlags.Static | BindingFlags.SetField,
       null, null, new Object[] { 5 });
}
catch (MissingFieldException e)
{
   // Show the user that the AField field cannot be accessed.
   outputBlock.Text += String.Format("Unable to access the AField field: {0}", e.Message) + "\n";
}
