如何从客户端在WCF服务中设置属性 [英] How to set a property in a WCF service from client side

问题描述

大家好，

首先，我是WCF的新手.我知道这是我的问题的基本问题！

我想打电话给我的WCF服务，并且可以正常运行.
我想要的是对服务的每次调用都包含一个已填充的LoginUser对象.

Hello everyone,

first of all I am new to WCF. That is the basic problem to my problem, I know!

I want to make a call to my WCF service and in that works OK.
What I want is that each call to the Service contains a filled LoginUser object.

[Serializable]
    [DataContract]
    public class LoginUser
    {
        [DataMember]
        public string UserName { get; set; }
        [DataMember]
        public string Password { get; set; }
    }

在我的界面中，我说:

In my Interface I state:

BLL.LoginUser LoginUser { [OperationContract] get; [OperationContract]set; }

在我的服务班里，我有:

In my service class I have:

public BLL.LoginUser LoginUser { [OperationBehavior]get; [OperationBehavior]set; }

在客户端中，我有2种方法(get_LoginUser()和set_LoginUser())，但我想查看一个属性.

我使用这些方法进行了测试，可以使用该方法设置UserName和Password的值，但是当调用下一个方法时，我的Loginuser对象再次为NULL.

这就是为什么我要设置一个属性，并且在下一次调用中LoginUser对象仍然具有该数据的原因.
我不想在WCF调用中将LoginUser对象添加为参数，或者这是唯一的选择吗?

我将对服务的呼叫实例化为:

In the client I get 2 methods (get_LoginUser() ans set_LoginUser()) but I want to see a property.

I tested with these methods and I can set the values for UserName and Password with the method, but when calling the next method my Loginuser object is NULL again.

That is why I want to have a property to set and that in the next call the LoginUser object still has the data.

I do not want to add the object of LoginUser as a parameter in the WCF call or is that the only option?

I instantiate my call to the service as:

srPersonal.IStatistics sc = new srPersonal.StatisticsClient();

然后我想做一个

I then want to do a

srPersonal.BLL.LoginUser lu = new srPersonal.BLL.LoginUser();
lu.UserName = "hi";
lu.Password = "*****";
sc.LoginUser = lu;
var result = sc.GetMyData();

我必须更改什么?

What do I have to change?

推荐答案

WCF不允许接口上的属性. "get"和"set"将作为方法工作，而不是作为属性工作.

对于您而言，这将起作用:

WCF don''t allow properties on interfaces. The ''get'' and ''set'' will work as a methods, but not as a property.

In your case, this will work:

ServiceReference1.IService1 proxy = new ServiceReference1.Service1Client();
ServiceReference1.LoginUser lu =
    new ServiceReference1.LoginUser() { UserName = "hi", Password = "****" };
proxy.set_UserLogin(lu);
var result = proxy.get_UserLogin();

您可以进行常规的基本身份验证.这是一些工作，但是它是处理用户名和密码的更好方法.

You could do a regular basic authentication. It is some work, but it is a better way to handle user name and passwords.
