在 .NET 核心控制台應用程序中將 appsettings.json 設置放入 class 類型的 object 中

Question

我想將配置從appsettings.json拉到ExchangeOptions類型的 object 中。 我知道configuration.Get<T>()在 ASP.NET 核心中工作，但我忘記了 .NET 核心控制台應用程序的正確 package。 我目前有以下 NuGet 包：

• Microsoft.Extensions.Configuration
• Microsoft.Extensions.Configuration.FileExtensions
• Microsoft.Extensions.Configuration.Json

下面的示例非常不言自明。

appsettings.json

{
  "ExchangeConfiguration": {
    "Exchange": "Binance",
    "ApiKey": "modify",
    "SecretKey": "modify"
  }
}

程序.cs

using Microsoft.Extensions.Configuration;
using System;

public class ExchangeOptions
{
    public Exchange Exchange { get; set; }
    public string ApiKey { get; set; }
    public string SecretKey { get; set; }
}

class Program
{
    static void Main(string[] args)
    {
        IConfiguration configuration = new ConfigurationBuilder()
            .AddJsonFile("appsettings.json")
            .Build();
    
        // These work fine
        var exchange = configuration["ExchangeConfiguration:Exchange"];
        var apiKey = configuration["ExchangeConfiguration:ApiKey"];
        var secretKey = configuration["ExchangeConfiguration:SecretKey"];

        // This doesn't work, because I don't have the right NuGet package
        ExchangeOptions exchangeOptions = configuration.Get<ExchangeOptions>();
    
        Console.ReadKey();
    }
}

Answer 1

configuration.Get<ExchangeOptions>()的正確 package 是Microsoft.Extensions.Configuration.Binder 。 不管怎么說，還是要謝謝你！
