Question

我有一个具有一些属性的类

public class SendData
{
public int MerchantID{get; set;}
public string Name{get; set;}
public int Age{get; set;}
}

然后在按钮上单击并将用户数据初始化为此类的对象。

button_click()
{
SendData senddata = new SendData();

senddata.MerchantID = Convert.ToInt32(txtMerchantid.Text);
senddata.Age = Convert.ToInt32(txtAge.Text);
senddata.Name= txtName.Text;

Webservice1.ReceiveDataService serviceObj = new Webservice1.ReceiveDataService();

public bool result = serviceObj.UpdateData(senddata); // calling web service
if(result) //Here is the scenario
lblresult.Text="Updated";
else
lblresult.Text="Operation unsuccessful";
}

现在我如何在webservice方法中读取此对象的所有字段？

我的网络方法：

public bool updatedata()//How to pass that object here
{
 //How can i get those three values in three separate fields in this method like.
 string name =""; //that name from UI;
 int id = ;//Id from UI
 int age= ;//Age from UI 
 //All the field need to be stored in database those coding will come here.
 return true;
}

它很简单，但请帮助我，你也可以建议我一些最佳和替代的方法来实现。谢谢，

您需要具有SendData类型的参数，此类型应存在于Web服务应用程序中，并且可供使用应用程序访问。

public bool updatedata(SendData sendDate)//How to pass that object here
{
    //How can i get those three values in three separate fields in this method like.
    string name =""; //that name from UI;
    int id = ;//Id from UI
    int age= ;//Age from UI 
}

我们应该在web方法之前添加xmlInclude类，以便让类暴露给客户端。

[WebMethod]    
[XmlInclude(typeof(Class_Name))]
public bool updatedata(Class_Name ObjectName)
{
string name =ObjectName.Name;
int id = ObjectName.ID;
int age= ObjectName.Age;
//Here the code for database storage etc., etc., and return the value...
return true;
}

Client has to create the proxy class and pass the object to this web service to do the functionalities.

（Can't send object to SOAP Web Service）
