原文: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;
