示例

下面的示例尝试从 mscorlib 程序集加载不存在的类型。The following example attempts to load a non-existent type from the mscorlib assembly. 捕获产生的异常,并显示 TypeNameMessage 值。The resulting exception is caught, and the TypeName and Message values are displayed. 若要运行此代码示例,必须提供完全限定的程序集名称。For this code example to run, you must provide the fully qualified assembly name. 有关如何获取完全限定的程序集名称的信息,请参阅程序集名称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);
      }  
   }
}
