推荐答案

您是否查看过 Window 的 WindowStartupLocation 属性?

CenterScreen 将Window放置在包含光标的屏幕中央，通常应该没问题.例如，如果用户单击窗口"上的按钮并打开一个对话框，则光标仍将位于该按钮上方，因此该对话框将显示在同一窗口的中央.

CenterScreen places the Window in the center of the screen containing the cursor, which should normally be fine. For example, if a user clicks a button on your Window and a dialog opens, the cursor will still be over the button and thus the dialog will show up in the center of the same Window.

CenterOwner 将对话框放置在指定为其所有者的窗口的中央.声明类似于以下内容的新窗口:

CenterOwner places the Dialog in the center of the Window specified as it's owner. Declare the new Window similar to this:

MyDialog d = new MyDialog { Owner = parentWindow };
d.ShowDialog();
