我用dotnet new console -o MyApp -f net6.0命令创建了.net程序，就像在https://dotnet.microsoft.com/en-us/learn/dotnet/hello-world-tutorial/create中记录的那样
我修改了文件：
Program.cs

global using System.Windows.Forms;

System.Console.WriteLine("Primary screen resolution: " + SystemInformation.PrimaryMonitorSize);
System.Console.WriteLine("Virtual size: " + SystemInformation.VirtualScreen);
System.Console.WriteLine("Monitors count: " + SystemInformation.MonitorCount);

但是当我运行PS C:\Users\box\Desktop\dotnet\MyApp> dotnet run
我得到错误-如何修复它？

C:\Users\box\Desktop\dotnet\MyApp\Program.cs(1,29): error CS0234: The type or namespace name 'Form
s' does not exist in the namespace 'System.Windows' (are you missing an assembly reference?) [C:\U
sers\box\Desktop\dotnet\MyApp\MyApp.csproj]

The build failed. Fix the build errors and run again.

我在Notepad.exe中编写程序-我需要特殊的程序来运行它吗？我在我的程序中使用https://learn.microsoft.com/en-us/dotnet/api/system.windows.forms.systeminformation?view=windowsdesktop-6.0，它提到：
“命名空间：System.Windows.Forms”
“程序集：System.Windows.Forms.dll”
不知何故，我的程序是失踪的引用，我想，但如何做到这一点呢？
