c# - AspNetCore 设置内容根路径

Question

怎么改Content root path在应用程序 .Net Core 3.0 ASP Blazor 上启动？
现在应用程序以输出开始

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.

      Hosting environment: Production

      Content root path: C:\Windows\system32

我要换 Content root path来自 C:\Windows\system32到应用程序初始化的另一条路径。

如何更改 Content root path在 AspNetCore 应用程序上启动？

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 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>();
                });
