ConfigurationModel和强类型配置
本文关键字:配置 强类型 ConfigurationModel | 更新日期: 2023-09-27 18:16:27
我喜欢新的ASP。. NET 5配置库,所以我想在控制台应用程序中使用它。它可以很好地用于松散类型的配置。但是我不知道如何使用强类型版本。
如何从这里工作?我有两个类
class Vehicle
{
public string Description { get; set; }
public int Mpg { get; set; }
public Paint Paint { get; set; }
}
class Paint
{
public string MajorColor { get; set; }
public string MinorColor { get; set; }
}
和配置文件:
<config>
<vehicle>
<description>Truck</description>
<mpg>20</mpg>
<paint>
<majorcolor>white</majorcolor>
<minorcolor>black</minorcolor>
</paint>
</vehicle>
</config>
我如何使用它?
var config = new Configuration();
config.AddXmlFile("../../StrongeConfig.xml");
?
第一个不工作的解:
var path = Path.GetFullPath("..''..''config.json");
var build = new ConfigurationBuilder()
.AddXmlFile(path);
var configuration = build.Build();
configuration.Bind(v);
Console.WriteLine(v.ToString());
给了我一辆空车

构建一个配置构建器,并使用它绑定到你的强类型对象
更新:
class MyConfig
{
public Vehicle Vehicle { get; set; }
}
class Vehicle
{
public string Description { get; set; }
public int Mpg { get; set; }
public Paint Paint { get; set; }
}
class Paint
{
public string MajorColor { get; set; }
public string MinorColor { get; set; }
}
public class Program
{
public void Main(string[] args)
{
var config = new ConfigurationBuilder();
config.AddXmlFile(@"x.xml");
var configuration = config.Build();
//Approach 1 (top level object)
var topConfig = new MyConfig();
configuration.Bind(topConfig);
Console.WriteLine(topConfig.Vehicle.Paint.MajorColor);
//Approach 2 (scoped)
var vehicleSection = configuration.GetSection("Vehicle");
var vehicle = new Vehicle();
vehicleSection.Bind(vehicle);
Console.WriteLine(vehicle.Paint.MajorColor);
}
}
