在ASP.Net Web服务的构造函数中使用带有参数的自定义对象

Question

I have a custom type in my asp.net web service. I have parameterized constructor for the same type. But when I try to use the same type on client side I can only see the default constructor with no parameter. This is my type.

public class Task
{

    public string AssignedTo { get; set; }

    public int CallDuration { get; set; }

    public Task(string assignedTo,int callDuration)
    {
        AssignedTo = assignedTo;
        CallDuration = callDuration;
    }
}

Answer 1

I don't believe that SvcUtil (what VS uses when adding a service reference) will add it with the parameterized constructor.

What you can do instead, is put the class into a shared library that's added as a normal reference to both the server and client. When adding the service reference, reuse the types, and you can use your constructor because proxy types will not be created for reused types.

This is also useful if your types have helper methods you would like access to on the client.

Answer 2

Should work fine if you update the service reference on the client side. Not sure in a traditional web service, but in WCF the service needs to be running to do this.
