AppDomain.AssemblyLoad 事件

定义

在加载程序集时发生。Occurs when an assembly is loaded.

public:
 virtual event AssemblyLoadEventHandler ^ AssemblyLoad;
[add: System.Security.SecurityCritical]
[remove: System.Security.SecurityCritical]
public event AssemblyLoadEventHandler AssemblyLoad;
member this.AssemblyLoad : AssemblyLoadEventHandler 
Public Event AssemblyLoad As AssemblyLoadEventHandler

示例

下面的示例演示 AssemblyLoad 事件。The following sample demonstrates the AssemblyLoad event.

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.

using namespace System;
using namespace System::Reflection;
ref class Test
{
public:
   static void MyAssemblyLoadEventHandler( Object^ sender, AssemblyLoadEventArgs^ args )
   {
      Console::WriteLine( "ASSEMBLY LOADED: {0}", args->LoadedAssembly->FullName );
      Console::WriteLine();
   }

};

void PrintLoadedAssemblies( AppDomain^ domain )
{
   Console::WriteLine( "LOADED ASSEMBLIES:" );
   System::Collections::IEnumerator^ myEnum = domain->GetAssemblies()->GetEnumerator();
   while ( myEnum->MoveNext() )
   {
      Assembly^ a = safe_cast<Assembly^>(myEnum->Current);
      Console::WriteLine( a->FullName );
   }

   Console::WriteLine();
}

int main()
{
   AppDomain^ currentDomain = AppDomain::CurrentDomain;
   currentDomain->AssemblyLoad += gcnew AssemblyLoadEventHandler( Test::MyAssemblyLoadEventHandler );
   PrintLoadedAssemblies( currentDomain );
   
   // Lists mscorlib and this assembly
   // You must supply a valid fully qualified assembly name here.
   currentDomain->CreateInstance( "System.Windows.Forms, Version, Culture, PublicKeyToken", "System.Windows.Forms.TextBox" );
   
   // Loads System, System::Drawing, System::Windows::Forms
   PrintLoadedAssemblies( currentDomain );
   
   // Lists all five assemblies
}

using System;
using System.Reflection;

class Test {

   public static void Main() {
      AppDomain currentDomain = AppDomain.CurrentDomain;
      currentDomain.AssemblyLoad += new AssemblyLoadEventHandler(MyAssemblyLoadEventHandler);
      
      PrintLoadedAssemblies(currentDomain);
      // Lists mscorlib and this assembly

      // You must supply a valid fully qualified assembly name here.      
      currentDomain.CreateInstance("System.Windows.Forms, Version, Culture, PublicKeyToken", "System.Windows.Forms.TextBox");
      // Loads System, System.Drawing, System.Windows.Forms
      
      PrintLoadedAssemblies(currentDomain);
      // Lists all five assemblies
   }
   
   static void PrintLoadedAssemblies(AppDomain domain) {
      Console.WriteLine("LOADED ASSEMBLIES:");
      foreach (Assembly a in domain.GetAssemblies()) {
         Console.WriteLine(a.FullName);
      }
      Console.WriteLine();
   }
   
   static void MyAssemblyLoadEventHandler(object sender, AssemblyLoadEventArgs args) {
      Console.WriteLine("ASSEMBLY LOADED: " + args.LoadedAssembly.FullName);
      Console.WriteLine();
   }
}
Option Strict On
Option Explicit On

Imports System.Reflection

Module Test
   
   Sub Main()
      Dim currentDomain As AppDomain = AppDomain.CurrentDomain
      AddHandler currentDomain.AssemblyLoad, AddressOf MyAssemblyLoadEventHandler
      
      PrintLoadedAssemblies(currentDomain)
      ' Lists mscorlib and this assembly

      ' You must supply a valid fully qualified assembly name here.

      Dim a As System.Reflection.Assembly
      For Each a In domain.GetAssemblies()
         Console.WriteLine(a.FullName)
      Next a
      Console.WriteLine()
   End Sub
   
   Sub MyAssemblyLoadEventHandler(sender As Object, args As AssemblyLoadEventArgs)
      Console.WriteLine("ASSEMBLY LOADED: " + args.LoadedAssembly.FullName)
      Console.WriteLine()
   End Sub

End Module 'Test 

注解

此事件的 AssemblyLoadEventHandler 委托指示加载的程序集。The AssemblyLoadEventHandler delegate for this event indicates what assembly was loaded.

若要为此事件注册事件处理程序,你必须具有所需的权限,或者引发 SecurityExceptionTo register an event handler for this event, you must have the required permissions, or a SecurityException is thrown.

有关处理事件的详细信息,请参阅处理和引发事件For more information about handling events, see Handling and Raising Events.

安全性

SecurityCriticalAttribute
需要对直接调用方的完全信任。Requires full trust for the immediate caller. 部分受信任的或透明的代码不能使用此成员。This member cannot be used by partially trusted or transparent code.
