.net code 3.0 获取配置文件 json 和 config 中的值

using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.FileProviders;

using System.IO;

方法:

/// <summary>
/// json配置文件读取
/// </summary>
/// <param name="configFileName"></param>
/// <param name="basePath"></param>
/// <returns></returns>
public static IConfigurationRoot GetJsonConfig(
string configFileName = "appsettings.json",
string basePath = "")
{
basePath = string.IsNullOrWhiteSpace(basePath) ? Directory.GetCurrentDirectory() : basePath;

var builder = new ConfigurationBuilder().
SetBasePath(basePath).
AddJsonFile(configFileName);
return builder.Build();
}

/// <summary>
/// xml配置文件读取
/// </summary>
/// <param name="configFileName"></param>
/// <param name="basePath"></param>
/// <returns></returns>
public static IConfigurationRoot GetXmlConfig(
string configFileName = "abc.config",
string basePath = "")
{
basePath = string.IsNullOrWhiteSpace(basePath) ? Directory.GetCurrentDirectory() : basePath;

var builder = new ConfigurationBuilder().
//SetBasePath(basePath).
AddXmlFile(b =>
{
b.Path = configFileName;
b.FileProvider = new PhysicalFileProvider(basePath);
});
return builder.Build();
}

调用:

var a = configXml.GetSection("Remotely:file:value").Value;

(Path)路径规则:"Remotely:file:value" 这串是路径path          用父子用:分开

例子

<?xml version="1.0" encoding="utf-8" ?>

<abc>

<Remotely>
　　　　<file value="https://baidu.com" />
</Remotely>

</abc>
