从UserControl关闭父窗口 [英] Close Parent window from UserControl

问题描述

大家好，



我在WPF中创建一个应用程序，它包含Window和一个Login UserControl

该用户控件是在运行时作为MainWindow中的子项添加，现在当我单击usercontrol的登录按钮时，它将登录并加载一个新窗口。但我想关闭之前的窗口，即登录窗口。

推荐答案

在用户控制'登录'按钮添加这个：



Window parentWindow = Window.GetWindow（this）;

parentWindow.Close（）;

In user control 'login' button add this:

Window parentWindow = Window.GetWindow(this);
parentWindow.Close();

试试这个

Try this

if ((this.Parent as ChildWindow) != null)
{
    (this.Parent as ChildWindow).Close();
}
