WebAPI项目框架新建读取配置文件帮助类

在.netcore webapi 项目中，我们会把配置信息同意放置在appsettings.json中，通过新建读取帮助类，更加简单的读取配置信息。

新建公共类库文件夹Common，新建公共类库Web.Core.Common

在Web.Core.Common类库下新建Helper文件夹，新建AppSettings帮助类

在AppSettings.cs里面添加以下代码：

/// <summary>
/// appsettings.json操作类
/// </summary>
public class AppSettings
{
static IConfiguration Configuration { get; set; }
static string contentPath { get; set; }

public AppSettings(string contentPath)
{
string Path = "appsettings.json";
Configuration = new ConfigurationBuilder()
.SetBasePath(contentPath)
.Add(new JsonConfigurationSource
{
Path = Path,
Optional = false,
ReloadOnChange = true
}).Build();
}

public AppSettings(IConfiguration configuration)
{
Configuration = configuration;
}
/// <summary>
/// 封装要操作的字符
/// </summary>
/// <param name="sections">节点配置</param>
/// <returns></returns>
public static string app(params string[] sections)
{
try
{

if (sections.Any())
{
return Configuration[string.Join(":", sections)];
}
}
catch (Exception)
{

}

return "";
}

/// <summary>
/// 递归获取配置信息数组
/// </summary>
/// <typeparam name="T"></typeparam>
/// <param name="sections"></param>
/// <returns></returns>
public static List<T> app<T>(params string[] sections)
{
List<T> list = new List<T>();
Configuration.Bind(string.Join(":", sections), list);
return list;
}
}
