Dry: .net core reading achieve custom configuration files, source code, oh

Optimistic people do not know how to read the configuration file in the .NET CORE, I have here the two points, on an introductory information on how to read the configuration file by appsettings.json. This will teach you a custom configuration file:

1. Create a configuration file in the project

{
  "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. The reference library Microsoft.Extensions.Configuration.Json operations and create a profile class ConfigHelper.cs

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

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

namespace the Common 
{ 
  public   class ConfigHelper 
    { 
        Private  static IConfiguration _configuration; 

        static ConfigHelper () 
        { 
            // current directory or Looking root directory file 
            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. Read the configuration file in the project

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