有一个简单的方法来确定它确实有在的WindowState =普通表格的大小，而无需实际改变形式的国家？

Is there an easy way to determine the size of a Form it does have in WindowState=Normal, without actually changing the Form state?

下面是我现在做的（C＃code）：

Here is what I do now (C# code):

public class MyForm: Form
{
     public void MyMethod()
     {
          // ...
          FormWindowState oldState = this.WindowState;
          this.WindowState = FormWindowState.Normal;

          Point windowLocation = this.Location;
          Size windowSize = this.Size;

          this.WindowState = oldState;
          //  ...
     }
}

这是我想了code的样子：

This is what I would like the code to look like:

public class MyForm: Form
{
     public void MyMethod()
     {
          // no state change here
          Point windowLocation = this.NormalStateLocation;
          Size windowSize = this.NormalStateSize;
     }
}

在事实上没有 NormalStateLocation 或 NormalStateSize 属性Windows窗体。

In fact there are no NormalStateLocation or NormalStateSize properties in Windows Forms.

推荐答案

我想要做同样的事情，因为没有人真正回答你的问题我张贴我的解决方案，现在，即使你已经满足了。也许有人需要它的某个时候。

I wanted to do the exact same thing and as nobody actually answered your question I'm posting my solution now even though you were already satisfied. Maybe somebody needs it sometime.
