2011-08-12

添加一个类事件。

命名空间： EnvDTE80
程序集： EnvDTE80（在 EnvDTE80.dll 中）

语法

声明
Function AddEvent ( _
    Name As String, _
    FullDelegateName As String, _
    CreatePropertyStyleEvent As Boolean, _
    Location As Object, _
    Access As vsCMAccess _
) As CodeEvent

CodeEvent AddEvent(
    string Name,
    string FullDelegateName,
    bool CreatePropertyStyleEvent,
    Object Location,
    vsCMAccess Access
)

CodeEvent^ AddEvent(
    String^ Name, 
    String^ FullDelegateName, 
    [InAttribute] bool CreatePropertyStyleEvent, 
    Object^ Location, 
    vsCMAccess Access
)

abstract AddEvent : 
        Name:string * 
        FullDelegateName:string * 
        CreatePropertyStyleEvent:bool * 
        Location:Object * 
        Access:vsCMAccess -> CodeEvent

function AddEvent(
    Name : String, 
    FullDelegateName : String, 
    CreatePropertyStyleEvent : boolean, 
    Location : Object, 
    Access : vsCMAccess
) : CodeEvent

参数

Name
类型：System.String
必选。要添加的类事件的名称。

FullDelegateName
类型：System.String
必选。该事件要基于的委托的名称。此名称充当新事件处理程序的模板。

CreatePropertyStyleEvent
类型：System.Boolean
可选。创建具有属性样式访问器的事件。True 指示事件应当具有访问器，false 指示事件不应具有访问器。

Location
类型：System.Object

Access
类型：EnvDTE.vsCMAccess
可选。一个 vsCMAccess 常数。

返回值

类型：EnvDTE80.CodeEvent
返回已创建的类事件处理程序。

提示

在进行某些类型的编辑之后，代码模型元素（如类、结构、函数、特性、委托等）的值可能是非确定性的，这意味着不能指望它们的值总是保持不变。有关更多信息，请参见使用代码模型查找代码 (Visual Basic) 中的“代码模型元素的值可能会更改”一节。

示例

[Visual Basic]

Sub AddEventExample(ByVal dte As DTE2)
    ' Before running this example, open a code document from a project
    ' and place the insertion point inside a class definition.
    Try
        ' Retrieve the CodeClass at the insertion point.
        Dim sel As TextSelection = _
            CType(dte.ActiveDocument.Selection, TextSelection)
        Dim cls As CodeClass = _
            CType(sel.ActivePoint.CodeElement( _
            vsCMElement.vsCMElementClass), CodeClass)

        ' Create a new event handler.
        cls.AddEvent("NewOnConnection", "OnConnection", True, -1, 
          vsCMAccess.vsCMAccessPublic)
    Catch ex As Exception
        MsgBox(ex.Message)
    End Try
End Sub

[C#]

public void AddEventExample(DTE2 dte)
{
    // Before running this example, open a code document from a project
    // and place the insertion point inside a class definition.
    try
    {
        // Retrieve the CodeClass at the insertion point.
        TextSelection sel = 
            (TextSelection)dte.ActiveDocument.Selection;
        CodeClass cls = 
            (CodeClass)sel.ActivePoint.get_CodeElement(
            vsCMElement.vsCMElementClass);
        // Creates a new event handler.
        cls.AddEvent("NewOnConnection", "OnConnection", true, -1, 
          vsCMAccess.vsCMAccessPublic);
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
