我在 gsoap 客户端 c++ 调用我的简单 wcf 服务时遇到问题，该服务公开：

public double Add(double n1, double n2) {
    double result = n1 + n2;
    return result;
}

下面是我的 gsoap 客户端测试代码：

BasicHttpBinding_USCORERestaurantService svc;
_ns1__Add         request;
_ns1__AddResponse response;

//svc->endpoint
double n1 = 1.12;
double n2 = 2.32;

request.n1 =&n1;
request.n2= &n2;
svc.soap->keep_alive=1;
int iResult = svc.__ns1__Add(&request, &response); // response result always return 0

我在服务上有一个断点，n1,n2 的参数始终为 0；

下面是我的wsdl文件：

当 WCF 服务在请求 Add(int n1, int n2) 时总是返回 0 时，我遇到了同样的问题。经过长时间的工作，我找到了解决方法，我的解决方法是应用 gSoap 2.7.16 而不是最后的 2.8.1_2，它可以完美运行。

下班后，我已经修复了这个问题，如果您使用的是 WCF ，则需要在操作中添加一个属性，例如：

[ServiceContract]
    public interface IMyService
    {
        [OperationContract]
        [XmlSerializerFormat(Style = OperationFormatStyle.Rpc, Use = OperationFormatUse.Literal)]
        long Method1(int a, int b, long c, string d);
     }

因此 gsoap 可以正确地将参数值发送到服务器。
