c# 获取屏幕DPI

方法一：用ManagementClass来获取。需要引入System.Management.dll;

using (ManagementClass mc = new ManagementClass("Win32_DesktopMonitor")) { using (ManagementObjectCollection moc = mc.GetInstances()) { int PixelsPerXLogicalInch = 0; // dpi for x int PixelsPerYLogicalInch = 0; // dpi for y foreach (ManagementObject each in moc) { PixelsPerXLogicalInch = int.Parse((each.Properties["PixelsPerXLogicalInch"].Value.ToString())); PixelsPerYLogicalInch = int.Parse((each.Properties["PixelsPerYLogicalInch"].Value.ToString())); } Console.WriteLine("PixelsPerXLogicalInch:" + PixelsPerXLogicalInch.ToString()); Console.WriteLine("PixelsPerYLogicalInch:" + PixelsPerYLogicalInch.ToString()); Console.Read(); } } View Code

方法二：用Graphics来获取。需要引入 System.Drawing.dll ;

using (Graphics graphics = Graphics.FromHwnd(IntPtr.Zero)) { float dpiX = graphics.DpiX; float dpiY = graphics.DpiY; } View Code
