我在截取窗口的屏幕截图时遇到了问题。

这是我正在使用的代码：

using System;
using System.Drawing;
using System.Drawing.Imaging;
using System.Runtime.InteropServices;

namespace Alerts
{
    class ImgSearch
    {
        [DllImport("user32.dll", CharSet = CharSet.Auto)]
        public static extern IntPtr FindWindow(string strClassName, string strWindowName);
        [DllImport("user32.dll")]

            public int Top { get; set; }
            public int Right { get; set; }
            public int Bottom { get; set; }
        }

        public static void ScreenShotWindow(IntPtr whandle)
        {
            // Get the …

我正在尝试将鼠标右键单击发送到窗口指定的坐标。

代码1：

[DllImport("user32.dll")]
public static extern int SendMessage(IntPtr hWnd, int Msg, int wParam, int lParam);
[DllImport("user32.dll")]        
static extern bool ScreenToClient(IntPtr hWnd, ref POINT lpPoint);

public struct POINT
{
    public int x;
    public int y;
}

var client = Process.GetProcessesByName("client_dx");
var whandle = client.MainWindowHandle;

POINT point = new POINT();
point.x = 1836;
point.y = 325;
ScreenToClient(whandle, ref point);
int lparm = (point.x << 16) + point.y;    
int lngResult = SendMessage(whandle, 0x0204, 0, lparm);
int lngResult2 = SendMessage(whandle, 0x0205, 0, lparm); …
