如何更改Content root path应用程序.Net Core 3.0 ASP Blazor启动？现在应用开始输出

info: Microsoft.AspNetCore.DataProtection.KeyManagement.XmlKeyManager[0]
      User profile is available. Using 'C:\Users\Art\AppData\Local\ASP.NET\DataProtection-Keys' as key repository and Windows DPAPI to encrypt keys at rest.
!!! C:\Program Files\WindowsApps\6c2bb0ad-5956-4886-9e3f-2135ebe50d2f_1.0.8.0_x64__n37t8n8dtxdg6\TUTDF_Viewer_v2\

      Now listening on: https://localhost:5001

      Application started. Press Ctrl+C to shut down.

      Hosting environment: Production

      Content root path: C:\Windows\system32

我需要Content root path从C:\Windows\system32初始化到应用程序初始化的另一条路径。

如何Content root path在AspNetCore应用启动时更改？

最正确的方法是更改项目的Program.cs-添加

var p = System.Reflection.Assembly.GetEntryAssembly().Location;
                    p = p.Substring(0, p.LastIndexOf(@"\") + 1);
webBuilder.UseContentRoot(p);

在中CreateHostBuilder。

完整示例：

public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .ConfigureWebHostDefaults(webBuilder =>
                {
                    var p = System.Reflection.Assembly.GetEntryAssembly().Location;
                    p = p.Substring(0, p.LastIndexOf(@"\") + 1);

                    webBuilder.UseContentRoot(p);
                    webBuilder.UseStartup<Startup>();
                });
