我有一段这样的代码:
[return: XmlElement("return", Namespace = "", IsNullable = false, DataType = "base64Binary")]
public byte[] WORK([XmlElement(Namespace = "http://www.example.com/xml/someapi", DataType = "string", Form = XmlSchemaForm.Qualified)] string guid, [XmlElement(Namespace = "http://www.example.com/xml/someapi", DataType = "base64Binary", Form = XmlSchemaForm.Qualified)] byte[] data) {
// some work
}

属性return:是什么意思?

Console.ReadLine();
}
[return: Test2(g = 5)]
public static Test1 call()
{
Test1 t1 = new Test1();
Test2 t2 = new Test2();
return t1;
}
}
class Test1 : Attribute

}
class Test2 : Attribute
{
public int g;
}
}

这里的方法call()仅返回Test1对象,但是attrbite用class 设置return的目的是什么Test2(g = 5)?
应该改变还是发生?但是什么也没发生...有人能解释发生了什么吗? …
