我有一个简单的服务定义：

[ServiceContract]
public interface IInterface12
{

    [OperationContract]
    void SendInterface12(string appId);
}

我在服务中实施为：

public void SendInterface12(string appId)
{

问题是字符串参数 appId 没有显示出来。完整的 WSDL 在这里：

      <?xml version="1.0" encoding="UTF-8"?>

我错过了什么？我必须有一个带有参数的服务操作，但是当我生成代理时，字符串 appId 参数没有参数。它说它需要0个参数。

很可能 WSDL 引用了定义参数的 XSD 文件。搜索“import”或“include”以查看该 XSD 的位置。如果这是您的 wsdl 位置：http ://myserver.com/X.svc?WSDL=WSDL0那么 XSD 位于http://myserver.com/x.svc?XSD=XSD0（或 XSD1、XSD2... ）。可能您的 WSDL 引用了另一个 WSDL (WSDL1)，它是引用 XSD（或其中一些）的那个。
