干货：.net core实现读取自定义配置文件，有源代码哦

看好多人不懂在.net core中如何读取配置文件，我这里分了两篇，上一篇介绍了怎样通过appsettings.json配置读取文件信息。这一篇教大家自定义配置文件：

1.在项目下创建配置文件

{
  "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.引用类库microsoft.extensions.configuration.json并创建配置文件操作类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()
        {
            //在当前目录或者根目录中寻找文件
            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.在项目中读取配置文件

string imgpath = confighelper.getsectionvalue("filemap:imgpath");
return imgpath;
