ComponentEventArgs 类

定义

命名空间:

System.ComponentModel.Design

程序集:

System.ComponentModel.TypeConverter.dll

Source:

ComponentEventArgs.cs

为 ComponentAdded、ComponentAdding、ComponentRemoved 和 ComponentRemoving 事件提供数据。

public ref class ComponentEventArgs : EventArgs

public class ComponentEventArgs : EventArgs

type ComponentEventArgs = class
    inherit EventArgs

Public Class ComponentEventArgs
Inherits EventArgs

继承

Object

EventArgs

ComponentEventArgs

示例

以下示例演示如何创建 ComponentEventArgs。

public:
   // This example method creates a ComponentEventArgs using the specified argument.
   // Typically, this type of event args is created by a design mode subsystem.
   ComponentEventArgs^ CreateComponentEventArgs( IComponent^ component )
   {
      // The component that is related to the event:  args.Component
      return gcnew ComponentEventArgs( component );
   }

// This example method creates a ComponentEventArgs using the specified argument.
// Typically, this type of event args is created by a design mode subsystem.  
public ComponentEventArgs CreateComponentEventArgs(IComponent component)
{
    ComponentEventArgs args = new ComponentEventArgs(component);

    // The component that is related to the event:  args.Component

    return args;
}

' This example method creates a ComponentEventArgs using the specified argument.
' Typically, this type of event args is created by a design mode subsystem.  
Public Function CreateComponentEventArgs(ByVal component As IComponent) As ComponentEventArgs

    Dim args As New ComponentEventArgs(component)

    ' The component that is related to the event:  args.Component

    Return args
End Function

注解

ComponentEventArgs 是所有组件管理事件的根事件参数类。 使用设计器添加或删除组件时，会发生此类型的事件。

构造函数

ComponentEventArgs(IComponent)

初始化 ComponentEventArgs 类的新实例。

属性

Component

获取与该事件关联的组件。

方法

Equals(Object)	确定指定对象是否等于当前对象。 (继承自 Object)
GetHashCode()	作为默认哈希函数。 (继承自 Object)
GetType()	获取当前实例的 Type。 (继承自 Object)
MemberwiseClone()	创建当前 Object 的浅表副本。 (继承自 Object)
ToString()	返回表示当前对象的字符串。 (继承自 Object)
