我有两个窗口 win1
用于显示用户列表,另一个 win2
用于添加用户。
在删除、更新或添加用户后,我还有一个刷新网格的方法。此方法在 win1
中。
我如何在添加用户后从 win2
调用此方法?

这是一个非常基本的面向对象的设计问题。 所以, 您想要在 < code> win2 code > 添加用户到 < code > win2 code > 后, 从 < code > win1 code > 调回 < code > 中的函数 。 那么, < code >win2 code > 是否有引用 < code > win1 code > 对象? 如果有, 那么您如何调回它 。 如果没有, 那么您需要给它一个函数( 将它转到构建者或其它东西 ) 。
或者,如果您使用MVVM框架, 您可以选择使用送信人。 大多数 MVVM 框架都包含一个框架, 并且非常有用 。 我建议您选择这条路线, 除非这是管道不值得的垃圾程序 。
You could use a custom event in your child window that the parent
window listens to
You could define a delegate in the child window that references a method in the parent window
You could use a messenger of some form: Here is a sample:

如果您从窗口1打开窗口 2, 您可以做一些类似的事情 :
// code in Window1
public void AddNewUser()
{
Window2 window = new Window2();
if (window.ShowDialog() == true)
{
// Update DataGrid
RefreshDataGrid();
}
}
