通过类属性的反射属性获取

Question

我发现类继承自接口：

  var baseType = typeof(ICustomSerialization);
  Assembly assembly = baseType.Assembly;

   var subClass = assembly.GetTypes().Where(t => t.IsSubclassOf(baseType) );

如果类有属性和参数名称：

    [CustomAttribute(Name="Soap")]
    class CustomSoapSerializer : ICustomSerialization

这是通过反射获取该属性的名称属性的方法吗？

Answer 1

试试这个

public static class CustomAttributeProviderExtensions
{
    public static TAttribute[] GetCustomAttributes<TAttribute>(this ICustomAttributeProvider self)
        where TAttribute:Attribute
    {
        return (TAttribute[])self.GetCustomAttributes(typeof(TAttribute), true);
    }
}

和用法

var baseType = typeof(ICustomSerialization);
Assembly assembly = baseType.Assembly;

var subClass = assembly.GetTypes().Where(t => baseType.IsAssignableFrom(t))
    .Where(t=>t.GetCustomAttributes<CustomAttribute>().Any(x=>x.Name == "Soap"))
    .ToList();
