我试图调整窗口的分辨率为1280×720与C＃。 我怎样才能做到这一点？ 我已经尝试了很多代码贴在这里，我得到的最接近的结果是这样的：
using System; using System.Diagnostics; using System.Runtime.InteropServices; namespace ConsoleApplication1 { class Program { [StructLayout(LayoutKind.Sequential)] public struct RECT { public int left; public int top; public int right; public int bottom; } [DllImport("user32.dll", SetLastError = true)] static extern bool GetWindowRect(IntPtr hWnd, ref RECT Rect); [DllImport("user32.dll", SetLastError = true)] static extern bool MoveWindow(IntPtr hWnd, int X, int Y, int Width, int Height, bool Repaint); static void Main(string[] args) { Process[] processes = Process.GetProcessesByName("notepad"); foreach (Process p in processes) { IntPtr handle = p.MainWindowHandle; RECT Rect = new RECT(); if (GetWindowRect(handle, ref Rect)) MoveWindow(handle, Rect.left, Rect.right, Rect.right-Rect.left, Rect.bottom-Rect.top + 50, true); } } } } 谢谢你的时间。
如果您希望窗口的大小为1280×720，则在MoveWindow调用中使用该大小。
MoveWindow(handle, Rect.left, Rect.top, 1280, 720, true);
为了回应大卫·阿马拉尔 （ David Amaral） ，为了使窗口居中，使用这个：
MoveWindow(handle, (Screen.PrimaryScreen.WorkingArea.Width - 1280) / 2, (Screen.PrimaryScreen.WorkingArea.Height - 720) / 2, 1280, 720, true);
顺便说一下，这是vb.net中的代码为谁想要的人：
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click Dim processes As Process() = Process.GetProcessesByName("notepad") For Each p As Process In processes Dim handle As IntPtr = p.MainWindowHandle Dim Rect As New RECT() If GetWindowRect(handle, Rect) Then MoveWindow(handle, (My.Computer.Screen.WorkingArea.Width - 1280) \ 2, (My.Computer.Screen.WorkingArea.Height - 720) \ 2, 1280, 720, True) End If Next End Sub <StructLayout(LayoutKind.Sequential)> _ Public Structure RECT Public left As Integer Public top As Integer Public right As Integer Public bottom As Integer End Structure <DllImport("user32.dll", SetLastError:=True)> _ Private Shared Function GetWindowRect(hWnd As IntPtr, ByRef Rect As RECT) As Boolean End Function <DllImport("user32.dll", SetLastError:=True)> _ Private Shared Function MoveWindow(hWnd As IntPtr, X As Integer, Y As Integer, Width As Integer, Height As Integer, Repaint As Boolean) As Boolean End Function
