此前问过与我的问题类似的问题。但我认为这是独一无二的。
我有我的PC显示器和扩展显示器，我通过此代码获得了EDID和一些数据：
ManagementObjectSearcher searcher =
new ManagementObjectSearcher("root\\WMI", "SELECT * FROM WmiMonitorID");
foreach (ManagementObject queryObj in searcher.Get())
{
dynamic snid = queryObj["SerialNumberID"];
string serialnum = GetStringFromInt(snid);
Console.WriteLine("SerialNumber: {0}",serialnum);
Console.WriteLine("YearOfManufacture: {0}", queryObj["YearOfManufacture"]);
dynamic code = queryObj["ProductCodeID"];
string pcid = GetStringFromInt(code);
code = queryObj["ManufacturerName"];
string manufactrName = GetStringFromInt(code);
Console.WriteLine("ProductCodeID: " + pcid);
Console.WriteLine("Manufacture: " + manufactrName);
}}
所以我将Manufacture和ProductCodeID结合起来，就像ABC3401和DEF4561（我有两个监听器）。我需要将我的申请移至DEF4561。我尝试Move Form onto specified Screen，但名称返回\\DISPLAY1，\\DISPLAY2等。我需要ABC3401 strng来识别监视器。我不知道如何结合这些结果。

要完成答案，我正在填写此内容。首先，通过edokan's answer
获取监视器的详细信息 public struct DisplayInfo
{
public string DisplayID;
public string DisplayName;
public string EDID;
}
[DllImport("user32.dll")]
static extern bool EnumDisplayDevices(string lpDevice, uint iDevNum, ref DISPLAY_DEVICE lpDisplayDevice, uint dwFlags);
[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int X, int Y, int cx, int cy, SetWindowPosFlags uFlags);
public static List<DisplayInfo> GetConnectedMonitorInfo()
{
var MonitorCollection = new List<DisplayInfo>();
DISPLAY_DEVICE d = new DISPLAY_DEVICE();
d.cb = Marshal.SizeOf(d);
try
{
for (uint id = 0; EnumDisplayDevices(null, id, ref d, 0); id++)
{
EnumDisplayDevices(d.DeviceName, 0, ref d, 1);
if (string.IsNullOrEmpty(d.DeviceName.ToString())
&& string.IsNullOrEmpty(d.DeviceID.ToString())) continue;
var dispInfo = new DisplayInfo();
dispInfo.DisplayID = id.ToString();
dispInfo.DisplayName = d.DeviceName.ToString();
dispInfo.EDID = d.DeviceID.ToString();
if (d.DeviceID.ToString().Contains("ABC4562"))
{
//Identify Multiple monitor of same series
if (string.IsNullOrEmpty(myMonitor.myMonDevName))
{
myMonitor.myMonDevName = d.DeviceName.ToString();
}
else
{
MultipleMonitorFound = true;
}
}
MonitorCollection.Add(dispInfo);
d.cb = Marshal.SizeOf(d);
}
}
catch (Exception ex)
{
LogError(ex.ToString());
}
return MonitorCollection;
}
现在我们有了监视器列表及其详细信息。现在需要将GUI更改为该监视器，
我们需要一些方法：
//I am Using WPF
//For C# only, we can use GetActiveWindow() API.
WindowInteropHelper winHelp = new WindowInteropHelper(this);
ScreenObject sc = new ScreenObject();
//Compare the name with screens
sc.screen = sc.GetMyMonitor(myMonitor.myMonDevName);
ScreenObject课程来自Move form onto the specified screen回答。
public static void MoveWindowToMonitor(IntPtr hWnd, int left, int top,double width, double height)
{
if (SetWindowPos(hWnd, (IntPtr)SpecialWindowHandles.HWND_TOP, left, top, (int)width, (int)height, SetWindowPosFlags.SWP_SHOWWINDOW))
LogError( " : Success");
else
LogError(" : Failed");
}
P/Invoke可以帮助你。
C＃WPF用户的说明：
如果您使用Windows Presentation Foundation，则需要使用WindowInteropHelper来获取Window句柄。
确保您引用了PresentationFramework程序集。
将其插入使用块
using System.Windows.Interop;
创建WindowInteropHelper的实例
WindowInteropHelper winHelp = new WindowInteropHelper(target);
然后使用GetHctiveWindowHandle（）的winHelp.Handle。

您必须使用EnumDisplayDevices枚举附加到它们的显示设备和显示器，然后使用可以匹配它们。
以下是来自pinvoke.net的无耻代码副本

}

void Main()
{

d.cb=Marshal.SizeOf(d);
try {
for (uint id=0; EnumDisplayDevices(null, id, ref d, 0); id++) {
Console.WriteLine(String.Format("{0}, {1}, {2}, {3}, {4}", id, d.DeviceName, d.DeviceString, d.StateFlags, d.DeviceID));
EnumDisplayDevices(d.DeviceName, 0, ref d, 1);
Console.WriteLine(String.Format(" {0}, {1}, {2}, {3}, {4}", id, d.DeviceName, d.DeviceString, d.StateFlags, d.DeviceID));
d.cb=Marshal.SizeOf(d);
}
} catch (Exception ex) {
Console.WriteLine(String.Format("{0}",ex.ToString()));
