定义

命名空间:

程序集:

当鼠标指针位于该项上时，在松开鼠标按钮时发生。

public event System.Windows.Forms.MouseEventHandler? MouseUp;

member this.MouseUp : System.Windows.Forms.MouseEventHandler 

Public Custom Event MouseUp As MouseEventHandler 

事件类型

MouseEventHandler

示例

下面的代码示例演示了此成员的用法。 在此示例中，事件处理程序报告事件的发生情况 MouseUp 。 此报告可帮助你了解事件发生的时间，并可以帮助你进行调试。 若要报告多个事件或频繁发生的事件，请考虑将 MessageBox.ShowConsole.WriteLine 消息替换为 或将消息追加到多行 TextBox。

若要运行示例代码，请将其粘贴到包含继承自 ToolStripItem的类型的实例（如 ToolStripButton 或 ToolStripMenuItem）的项目中。 然后命名实例 ToolStripItem1 并确保事件处理程序与事件 MouseUp 相关联。

private void ToolStripItem1_MouseUp(Object sender, MouseEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Button", e.Button );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Clicks", e.Clicks );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "X", e.X );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Y", e.Y );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Delta", e.Delta );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Location", e.Location );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "MouseUp Event" );
}

Private Sub ToolStripItem1_MouseUp(sender as Object, e as MouseEventArgs) _ 
     Handles ToolStripItem1.MouseUp

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "Button", e.Button)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Clicks", e.Clicks)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "X", e.X)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Y", e.Y)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Delta", e.Delta)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Location", e.Location)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"MouseUp Event")

End Sub
