次の例では、mscorlib アセンブリから存在しない型を読み込もうとします。The following example attempts to load a non-existent type from the mscorlib assembly. 結果の例外がキャッチされ、 TypeNameMessageの値が表示されます。The resulting exception is caught, and the TypeName and Message values are displayed. このコード例を実行するには、完全修飾アセンブリ名を指定する必要があります。For this code example to run, you must provide the fully qualified assembly name. 完全修飾アセンブリ名を取得する方法については、「アセンブリ名」を参照してください。For information about how to obtain the fully qualified assembly name, see Assembly Names.

// Load the mscorlib assembly and get a reference to it.
// You must supply the fully qualified assembly name for mscorlib.dll here.
Assembly^ myAssembly = Assembly::Load( "Assembly text name, Version, Culture, PublicKeyToken" );
try
{
   Console::WriteLine( "This program throws an exception upon successful run." );
   
   // Attempt to load a non-existent type from an assembly. 
   Type^ myType = myAssembly->GetType( "System.NonExistentType", true );
}
catch ( TypeLoadException^ e ) 
{
   // Display the name of the Type that was not found.
   Console::WriteLine( "TypeLoadException: \n\tError loading the type '{0}' from the assembly 'mscorlib'", e->TypeName );
   Console::WriteLine( "\tError Message = {0}", e->Message );
}
catch ( Exception^ e ) 
{
   Console::WriteLine( "Exception: Error Message = {0}", e->Message );
}
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);
