Question

我正在尝试在我的应用程序中使用WCF Web服务，但是在添加服务引用和相应的using语句之后，我无法编译我的代码，并且在11行中出现以下错误11次数：

Error   7   The type name 'SignOnService' does not exist in the type 'FTXService.FTXService'    C:\Users\bdugan\documents\visual studio 2010\Projects\FTXService\FTXService\Service References\SignOnService\Reference.cs   130 20  FTXService

我知道服务存在，因为我过去在PHP中使用它，但我似乎无法弄清楚它为什么不起作用。这是Reference.cs：

有什么想法吗？

Answer 1

服务中有一个名为FTXService的类，嵌入在名为FTXService的名称空间中。从该服务生成客户端代理时，Visual Studio的服务生成器会混乱。它生成的代码似乎引用了servicerefence中使用的重新发生的命名空间，而不是要调用的服务类方法。

要解决此问题，请将服务实现的类重命名为（例如）FTXServiceImpl并重新生成客户端代理（在客户端项目中删除并添加服务引用）。

Answer 2

在Visual Studio中使用“添加服务引用”对话框时，通常会要求您指定命名空间。默认情况下为ServiceReference1。它还生成通常最终得到的强类型代理客户端类。所以客户端代理可能看起来像这样：

using (var client = new ServiceReference1.SomeNamespace.SignOnServiceClient())
{
    ...
}

只需右键单击生成的服务代理并浏览源代码即可查看确切创建的类。

Answer 3

根据您发布的Reference.cs，服务客户端名为SignOnClient，因此您需要以下内容：

var client = new SignOnClient();

或完全符合资格：

var client = new FTXService.SignOnService.SignOnClient();

换句话说，命名空间中不存在类型SignOnService（这是错误告诉你的），但SignOnClient确实存在。

当我尝试调试代码时，引用的WebService未显示
