Examples

The following example attempts to load a non-existent type from the mscorlib assembly. The resulting exception is caught, and the TypeName and Message values are displayed. For this code example to run, you must provide the fully qualified assembly name. For information about how to obtain the fully qualified assembly name, see Assembly Names.

using System;
using System.Reflection;

public class TypeLoadException_TypeName
{
   public static void Main()
   {
      // Get a reference to the assembly mscorlib.dll, which is always
      // loaded. (System.String is defined in mscorlib.)
      Assembly mscorlib = typeof(string).Assembly;

      try
      {
         Console.WriteLine("Attempting to load a type that does not exist in mscorlib.");
         // The boolean parameter causes an exception to be thrown if the
         // type is not found.
         Type myType = mscorlib.GetType("System.NonExistentType", true);
      }
      catch (TypeLoadException ex)
      {
         // Display the name of the type that was not found, and the
         // exception message.
         Console.WriteLine("TypeLoadException was caught. Type = '{0}'.",
             ex.TypeName);
         Console.WriteLine("Error Message = '{0}'", ex.Message);
      }
   }
}
