属性值
完全限定的类型名称
示例
以下示例尝试从 mscorlib 程序集加载不存在的类型。 捕获生成的异常,并 TypeName 显示值 Message 。 若要运行此代码示例,必须提供完全限定的程序集名称。 有关如何获取完全限定程序集名称的信息,请参阅 程序集名称。
// 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 );
}

// Get a reference to the assembly mscorlib.dll, which is always

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);
}
