乾貨：.net core實現讀取自定義配置文件，有源代碼哦

看好多人不懂在.NET CORE中如何讀取配置文件，我這裏分了兩篇，上一篇介紹了怎樣經過appsettings.json配置讀取文件信息。這一篇教你們自定義配置文件：

1.在項目下建立配置文件

{
  "FileMap": {
    "ImgPath": "D:\\myfile\\misc\\NPSPower\\TemplateCore\\TemplateCore\\wwwroot\\UpImg\\",
    "ImgWeb": "http://127.0.0.1:1994/UpImg/",
    "FilePath": "D:\\myfile\\misc\\NPSPower\\TemplateCore\\TemplateCore\\wwwroot\\UpFile\\",
    "FileWeb": "http://127.0.0.1:1994/UpFile/",
    "VideoPath": "D:\\myfile\\misc\\NPSPower\\TemplateCore\\TemplateCore\\wwwroot\\UpVideo\\",
    "VideoWeb": "http://127.0.0.1:1994/UpVideo/",
    "Web": "http://127.0.0.1:1994/"
  }
}

 

2.引用類庫Microsoft.Extensions.Configuration.Json並建立配置文件操做類ConfigHelper.cs

Install-Package Microsoft.Extensions.Configuration.Json -Version 3.0.0

using Microsoft.Extensions.Configuration;
using System;
using System.Collections.Generic;
using System.IO;
using System.Text;

namespace Common
{
  public  class ConfigHelper
    {
        private static IConfiguration _configuration;

        static ConfigHelper()
        {
            //在當前目錄或者根目錄中尋找文件
            var fileName = "Config/ManagerConfig.json";

            var directory = AppContext.BaseDirectory;
            directory = directory.Replace("\\", "/");

            var filePath = $"{directory}/{fileName}";
            if (!File.Exists(filePath))
            {
                var length = directory.IndexOf("/bin");
                filePath = $"{directory.Substring(0, length)}/{fileName}";
            }

            var builder = new ConfigurationBuilder()
                .AddJsonFile(filePath, false, true);

            _configuration = builder.Build();
        }

        public static string GetSectionValue(string key)
        {
            return _configuration.GetSection(key).Value;
        }
    }
}

3.在項目中讀取配置文件

string ImgPath = ConfigHelper.GetSectionValue("FileMap:ImgPath");
return ImgPath;
