ASP.NET Core——从静态类访问配置 [英] ASP.NET Core—access Configuration from static class

问题描述

我想要一个访问配置对象的简单静态类.所有配置信息都已从 Startup 类的 appsettings.json 文件中读取.我只需要一种简单的方法来访问它.这可能吗?

I want a simple static class that accesses the Configuration object. All the config info is already read in from the appsettings.json file in the Startup class. I just need an easy way to access it. Is this possible?

namespace MyNamespace
{
    public static class Config
    {
        public string Username => Configuration["Username"];
        public string Password => Configuration["Password"];
    }
}

应用中的其他任何地方:

Anywhere else in the app:

string username = Config.Username;
string password = Config.Password;

推荐答案

略短的版本，原理同上...

A slightly shorter version based on the same principle as above...

public Startup(IConfiguration configuration)
{
    Configuration = configuration;
    StaticConfig = configuration;
}

public static IConfiguration StaticConfig { get; private set; }

在另一个静态类中使用:

To use in another static class:

string connString = Startup.StaticConfig.GetConnectionString("DefaultConnection");
