c# - 配置绑定(bind)不起作用

Question

我有以下设置:

{
  "AppSettings": {
    "ConnectionString": "mongodb://localhost:27017",
    "Database": "local",
    "ValidOrigins": [ "http://localhost:61229" ]
  },
  "Logging": {
    "IncludeScopes": false,
    "Debug": {
      "LogLevel": {
        "Default": "Warning"
      }
    },
    "Console": {
      "LogLevel": {
        "Default": "Warning"
      }
    }
  }
}

我做绑定(bind):

    services.Configure<AppSettings>(Configuration.GetSection("AppSettings"));

我有以下设置文件:

    public class AppSettings
    {
        public string ConnectionString = "";
        public string Database = "";

        public List<string> ValidOrigins { get; set; }
    }

进行绑定(bind):

    AppSettings settings = new AppSettings();
    Configuration.GetSection("AppSettings").Bind(settings);

settings.ValidOrigins 没问题，但是 ConnectionString 和 Database 都是 null。我做错了什么？

Answer 1

Binder 只会绑定(bind)属性，不会绑定(bind)字段。尝试对 ConnectionString 和 Database 使用属性而不是字段。

public string ConnectionString { get; set; }

public string Database { get; set; }
