调用 GetClientRect winAPI [英] Call GetClientRect winAPI

问题描述

我在尝试调用 GetClientRect 并传入 Stuct 以填充返回值时遇到问题.这是我的代码.

I am having an issues trying to call the GetClientRect and passing in a Stuct to get populated with the values that are returned. Here is the code I have.

[return: MarshalAs(UnmanagedType.Bool)]
        [DllImport("user32.dll")]
        internal static extern bool GetClientRect(IntPtr hwnd, ref RECT lpRect);

        [StructLayout(LayoutKind.Sequential)]
        internal struct RECT
        {
            internal int left;
            internal int top;
            internal int right;
            internal int bottom;
        }
     RECT rect = new RECT();

     GetClientRect(PApplication.Instance.MdiMain.Handle, ref rect);

我一直收到 RECT 上的错误，提示错误 1 ​​嵌入式语句不能是声明或标记语句.

I keep getting the error on the RECT saysing Error 1 Embedded statement cannot be a declaration or labeled statement.

我只需要帮助从 GetClientRect 中取回左上右下值

I just need help getting back the left top right bottome values from the GetClientRect

推荐答案

我发现我把代码放在 if 之后，忘记添加 { } 所以我现在很好.

I found it I put the code after an if and forgot to add { } so I am good now.
