TypeLoadException Constructor (String)

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

Initializes a new instance of the TypeLoadException class with a specified error message.

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

Syntax

'Declaration
Public Sub New ( _
    message As String _
)

public TypeLoadException(
    string message
)

Parameters

message
Type: System.String
The message that describes the error.

Remarks

The content of the message parameter should be understandable to the user. The caller of this constructor is required to ensure that this string has been localized for the current system culture.

The following table shows the initial property values for an instance of TypeLoadException.

Property	Value
InnerException	A null reference (Nothing in Visual Basic).
Message	The error message string.

Examples

The following code example demonstrates the TypeLoadException(String) constructor. It contains a method that generates a TypeLoadException with a custom message, and displays the error message.

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


Public Class Example
   Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
      outputBlock.Text &= "This program throws an exception upon successful run." & vbCrLf
      outputBlock.Text &= "Generating TypeLoadException with custom message..." & vbCrLf
      Try
         ' Generate a new instance of TypeLoadException.
         TypeLoadExceptionDemoClass.GenerateException()
      Catch e As TypeLoadException
         outputBlock.Text &= ("TypeLoadException: " + ControlChars.Cr + ControlChars.Tab + "Error Message = " + e.Message) & vbCrLf
      Catch e As Exception
         outputBlock.Text &= ("Exception: " + ControlChars.Cr + ControlChars.Tab + "Error Message = " + e.Message) & vbCrLf
      End Try
   End Sub 'Main
End Class 'TypeLoadException_Constructor2

Class TypeLoadExceptionDemoClass
   Public Shared Function GenerateException() As Boolean
      ' Throw a TypeLoadException with custom defined message.
      Throw New TypeLoadException("This is a custom generated TypeLoadException error message")
   End Function 'GenerateException
End Class 'TypeLoadExceptionDemoClass

using System;

public class Example
{
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      outputBlock.Text += "This program throws an exception upon successful run." + "\n";
      outputBlock.Text += "Generating TypeLoadException with custom message..." + "\n";
      try
      {
         // Generate a new instance of TypeLoadException.
         TypeLoadExceptionDemoClass.GenerateException();
      }
      catch (TypeLoadException e)
      {
         outputBlock.Text += "TypeLoadException: \n\tError Message = " + e.Message + "\n";
      }
      catch (Exception e)
      {
         outputBlock.Text += "Exception: \n\tError Message = " + e.Message + "\n";
      }
   }
}

class TypeLoadExceptionDemoClass
{
   public static bool GenerateException()
   {
      // Throw a TypeLoadException with custom defined message.
      throw new TypeLoadException("This is a custom generated TypeLoadException error message");
   }
}
