_dispSolutionEvents_BeforeClosingEventHandler 委托

此 API 支持 .NET Framework 基础结构,不适合在代码中直接使用。

处理在解决方案关闭之前激发的事件。

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

语法

声明
<ComVisibleAttribute(False)> _
Public Delegate Sub _dispSolutionEvents_BeforeClosingEventHandler
[ComVisibleAttribute(false)]
public delegate void _dispSolutionEvents_BeforeClosingEventHandler()
[ComVisibleAttribute(false)]
public delegate void _dispSolutionEvents_BeforeClosingEventHandler()
[<ComVisibleAttribute(false)>]
type _dispSolutionEvents_BeforeClosingEventHandler = 
    delegate of unit -> unit
JScript 不支持委托。

备注

SolutionEvents 对象可能超出范围,进行垃圾回收后关闭解决方案。若要保留对此对象的引用,请在您实现解决方案事件处理程序的类中声明私有变量。

示例

public class Connect : IDTExtensibility2
{
    private SolutionEvents _solnEvents;

    public void OnConnection(object application, ext_ConnectMode connectMode, object addInInst, ref Array custom)
    {
        _applicationObject = (DTE2)application;
        _addInInstance = (AddIn)addInInst;

        _solnEvents = _applicationObject.Events.SolutionEvents;

        _solutionBeforeClosingEventHandler = new _dispSolutionEvents_BeforeClosingEventHandler(this.SolutionBeforeClosing);
        _solnEvents.BeforeClosing += _solutionBeforeClosingEventHandler;
    }

    private _dispSolutionEvents_BeforeClosingEventHandler _solutionBeforeClosingEventHandler

    private void SolutionBeforeClosing()
    {
        System.Windows.Forms.MessageBox.Show("SolutionBeforeClosing");
    }
}
