给定屏幕的有效分辨率列表? [英] List of valid resolutions for a given Screen?

问题描述

有没有一种方法可以获取给定屏幕的所有有效分辨率?

Is there a way to get ALL valid resolutions for a given screen?

我目前有一个下拉菜单，其中包含所有有效屏​​幕(使用 Screen.AllScreens ).当用户选择屏幕时，我想向他们显示第二个下拉列表，列出该显示的所有有效分辨率(不是仅是当前分辨率).

I currently have a dropdown that is populated with all valid screens (using Screen.AllScreens). When the user selects a screen, I'd like to present them with a second dropdown listing all valid resolutions for that display (not just the current resolution).

推荐答案

我认为应该可以使用 System.Management 名称空间.

I think it should be possible to get the information using Windows Management Instrumentation (WMI). WMI is accessible from .NET using the classes from them System.Management namespace.

解决方案将类似于以下内容.我不太了解WMI，无法立即找到您要查找的信息，但是我找到了视频卡支持的分辨率的WMI类.该代码需要引用System.Management.dll并导入System.Management命名空间.

A solution will look similar to the following. I don't know WMI well and could not immediately find the information you are looking for, but I found the WMI class for the resolutions supported by the video card. The code requires referencing System.Management.dll and importing the System.Management namespace.

var scope = new ManagementScope();

var query = new ObjectQuery("SELECT * FROM CIM_VideoControllerResolution");

using (var searcher = new ManagementObjectSearcher(scope, query))
{
    var results = searcher.Get();

    foreach (var result in results)
    {
        Console.WriteLine(
            "caption={0}, description={1} resolution={2}x{3} " +
            "colors={4} refresh rate={5}|{6}|{7} scan mode={8}",
            result["Caption"], result["Description"],
            result["HorizontalResolution"],
            result["VerticalResolution"],
            result["NumberOfColors"],
            result["MinRefreshRate"],
            result["RefreshRate"],
            result["MaxRefreshRate"],
            result["ScanMode"]);
    }
}
