C# WebService序列化请求丢失了Nullable属性

我从我的服务中得到一个wsdl.cs，wsdl使用wsdl.exe。然后通过使用CSharpCodeProvider生成dll

现在我使用dll，创建一个客户端来调用服务，但是一些可为null的int和decimal属性没有序列化到soap消息中。为什么?

这是我的密码

CSharpCodeProvider provider = new CSharpCodeProvider();
CompilerParameters cp = new CompilerParameters();
cp.GenerateExecutable = false;
cp.GenerateInMemory = true;
cp.OutputAssembly = dllFileName;
cp.ReferencedAssemblies.Add("System.dll");
cp.ReferencedAssemblies.Add("System.XML.dll");
cp.ReferencedAssemblies.Add("System.Web.Services.dll");
cp.ReferencedAssemblies.Add("System.Data.dll");
CompilerResults result = provider.CompileAssemblyFromFile(cp, csFileName);

    }
}

您可以看到缺少CustomerNumber。有人能帮我吗？

我解决了我的问题

这是因为这是OrderInfo类中的CustomerNumber指定属性，默认情况下为false，因此CustomerNumber不会序列化

[System.Xml.Serialization.XmlIgnoreAttribute()]
public bool CustomerNumberSpecified

每次我为CustomerNumber设置值时，我都会为CustomerNumber指定值设置true，这一切都很好

[System.Xml.Serialization.XmlIgnoreAttribute()]
public bool CustomerNumberSpecified
