AppDomain.AssemblyLoad 事件

定义

命名空间:

System

程序集:

System.Runtime.dll

Source:

AppDomain.cs

在加载程序集时发生。

public:
 event AssemblyLoadEventHandler ^ AssemblyLoad;

public event AssemblyLoadEventHandler? AssemblyLoad;

member this.AssemblyLoad : AssemblyLoadEventHandler 

Public Custom Event AssemblyLoad As AssemblyLoadEventHandler 

事件类型

AssemblyLoadEventHandler

示例

下面的示例演示 了 事件 AssemblyLoad 。

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。
