.Net Core 读取配置文件

话不多说直接上代码：

public static class MengTConfig
{
static IConfigurationRoot _MT_Configuration { get; }
static IConfigurationSection _MT_AppSetting;
static MengTConfig()
{
var builder = new ConfigurationBuilder()
.SetBasePath(AppContext.BaseDirectory)
.AddJsonFile("_config/MengT.json", optional: true, reloadOnChange: true);

_MT_Configuration = builder.Build();

_MT_AppSetting = _MT_Configuration.GetSection("AppSettings");

}
/// <summary>
/// 通过[Key]获取数据库连接字符串
/// </summary>
/// <param name="_key">Key</param>
/// <returns></returns>
public static string GetConnectionString(string _key)
{
return _MT_Configuration.GetConnectionString(_key);
}

/// <summary>
/// 通过[Key]获取配置信息
/// </summary>
/// <param name="_key">Key</param>
/// <returns></returns>
public static string GetAppSetting(string _key)
{
return _MT_AppSetting[_key];
}
}
