怎么解决用webservicesoapwsdl技术做的接口问题

WSDL (Web Services Description Language,Web 服务描述语言)确定该服务可用后，在（VS）项目上下菜单中选择 添加WEB引用。通过在URL处直接输入WSDL文件路径添加即可。

首先，要创建一个继承自System.Web.Services.Protocols.SoapHeader的RequestSOAPHeader类，在其中添加UserName和Password两个属性，代码如下：

public class RequestSOAPHeader : System.Web.Services.Protocols. SoapHeader

{

public string user { getset}

public string password { getset}

}

生成的WebService代理类中设置成属性成员：

public partial class ISysNotifyTodoWebServiceService

{

public RequestSOAPHeader RequestSOAPHeader { getset}

}

在访问的WebService方法上方添加SOAPHeader的声明：

[System.Web.Services.Protocols. SoapDocumentMethodAttribute( "", RequestNamespace="http://webservice.notify.sys/" , ResponseNamespace="http://webservice.notify.sys/" , Use=System.Web.Services.Description.SoapBindingUse .Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle .Wrapped)]

[ return: System.Xml.Serialization. XmlElementAttribute( "return", Form=System.Xml.Schema.XmlSchemaForm .Unqualified)]

[ SoapHeader( "RequestSOAPHeader")]

public notifyTodoAppResult setTodoDone([System.Xml.Serialization.XmlElementAttribute (Form=System.Xml.Schema.XmlSchemaForm .Unqualified)] notifyTodoRemoveContext arg0) {

object[] results = this.Invoke( "setTodoDone", new object[] {

arg0})

return (( notifyTodoAppResult)(results[0]))

}
