推荐答案

您从Process类开始获取所需的Process实例.然后，您可以使用它的MainWindowHandle属性获取应用程序启动表单的句柄.

You start with the Process class to get the Process instance you''re looking for. Then you can use it''s MainWindowHandle property to get the handle to the apps startup form.

[添加到Dave的答案中.]

您不能将Process.MainWindowHandle返回的句柄与Form.FromHandle之类的方法一起使用，因为该句柄尚未与应用程序中的Control 对象关联.与该窗口的任何交互都必须通过P/Invoking API，例如SetWindowText.

[Adding to Dave''s answer.]

You cannot use the handle returned from Process.MainWindowHandle with methods like Form.FromHandle because the handle is not already associated with a Control object in your application. Any interaction with that window will have to be through P/Invoking APIs like SetWindowText.
