1. 使用SetWindowPos设置位置

2. 用Screen

获取当前系统连接的屏幕数量： Screen.AllScreens.Count();

获取当前屏幕的名称：string CurrentScreenName = Screen.FromControl(this).DeviceName;

获取当前屏幕对象：Screen CurrentScreen = Screen.FromControl(this);

获取当前鼠标所在的屏幕：Screen CurrentScreen = Screen.FromPoint(new Point(Cursor.Position.X, Cursor.Position.Y));

Winform下，不需要任何引用直接添加代码,这两行代码表示将一个无边框的窗体全屏显示在第二个窗体上。

this.FormBorderStyle = FormBorderStyle.None;

this.DesktopBounds = Screen.AllScreens[1].Bounds;

获取所有窗体的显示比率：

Screen[] s = Screen.AllScreens;

ScreensRect = new Rectangle[s.Length];

for (int i = 0; i < s.Length; i++)

{

  ScreensRect[i] = s[i].WorkingArea;

}

获取第二屏的坐标：

int iX = ScreensRect[1].X;

int iY = ScreensRect[1].Y;

获取当前系统连接的屏幕数量：

Screen.AllScreens.Count();

获取当前屏幕的名称：

string CurrentScreenName = Screen.FromControl(this).DeviceName;

获取当前屏幕对象：

Screen CurrentScreen = Screen.FromControl(this);

获取当前鼠标所在的屏幕：

Screen CurrentScreen = Screen.FromPoint(new Point(Cursor.Position.X, Cursor.Position.Y));

让窗体在第2个屏幕上显示：

     this.Left = ((Screen.AllScreens[1].Bounds.Width - this.Width) / 2);

     this.Top = ((Screen.AllScreens[1].Bounds.Height - this.Height) / 2);

NET(C#)多屏(双屏)设置屏幕显示器分辨率方法代码(SetRes)

1、SetRes下载

下载地址：https://www.softpedia.com/get/Multimedia/Video/Other-VIDEO-Tools/Ian-Sharpe-SetRes.shtml

2、修改单屏代码

将下载的SetRes.exe拷到当前目录即可

System.Diagnostics.Process process = new System.Diagnostics.Process();

System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();

startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;

startInfo.FileName = "cmd.exe";

startInfo.Arguments = "/c setres h1920  v1080";

process.StartInfo = startInfo;

process.Start();

3、修改双屏代码

将下载的SetRes.exe拷到当前目录即可

System.Diagnostics.Process process = new System.Diagnostics.Process();

System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();

startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;

startInfo.FileName = "cmd.exe";

startInfo.Arguments = "/c SETRES m0:0 h1366 v768 && SETRES m1:0 h1280 v800";

process.StartInfo = startInfo;

process.Start();
