Question

在Visual Studio 2008 C＃应用程序中，我使用按钮控制。我尝试获取MouseDown事件的按钮（该事件在Button继承自的Control类中定义）如果我写这个：

this.button1.MouseDown += 
    new System.Windows.Forms.MouseEventHandler(this.Button_MouseDown);

它编译但是偶数没有被提升。

同样适用于整个小组本身

this.MouseDown += new System.Windows.Forms.MouseEventHandler(this.Button_MouseDown);

为什么我无法在派生类中使用该事件？有没有办法让它发挥作用？

这是我的InitializeComponent（）方法：

        private void InitializeComponent()
    {
        this.button1 = new System.Windows.Forms.Button();
        this.SuspendLayout();
        // 
        // button1
        // 
        this.button1.Location = new System.Drawing.Point(29, 140);
        this.button1.Name = "button1";
        this.button1.Size = new System.Drawing.Size(72, 39);
        this.button1.TabIndex = 1;
        this.button1.Text = "button1";
        this.button1.MouseDown += new System.Windows.Forms.MouseEventHandler(button1_MouseDown);
        // 
        // MopilStatsPanel
        // 
        this.AutoScaleDimensions = new System.Drawing.SizeF(96F, 96F);
        this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Dpi;
        this.Controls.Add(this.button1);
        this.Name = "MopilStatsPanel";
        this.Size = new System.Drawing.Size(286, 337);
        this.ResumeLayout(false);

    }

我认为你可能需要使用 MouseButtonEventHandler 而不只是 MouseEventHandler ：

this.MouseDown += new MouseButtonEventHandler(this.Button_MouseDown);

Button的MouseDown事件
