Implementing web service issue

Rock Star

Hi, I build a web service in .Net. After adding this web service as a web reference in my website and when I am trying to use the methods in a web services by creating the object of it, I am getting only two methods which are equals and reference equals anyone knows why I am facing this issue?

Well, some code snippets would be nice. It would help us help you :) One possibility without seeing your code is that your web service methods are missing the "WebMethod" attribute: VB.NET

<WebMethod()> \_
Public Function HelloWorld() As String
    Return "Hello World"
End Function

C#

\[WebMethod()\]
public string HelloWorld()
{  
    return "Hello World";
}

public class Service1 : System.Web.Services.WebService
{
public DataSet UserDataset = new DataSet();
public SqlDataAdapter UserAdapter = new SqlDataAdapter("Select Query",new SqlConnection("connection string"));

    \[WebMethod\]
    public string HelloWorld()
    {
        return "Hello World";
    }

    \[WebMethod\]
    public DataSet GetUserData()
    {
        UserAdapter.Fill(UserDataset);
        return UserDataset;
    }

    \[WebMethod\]
    public DataSet UpdateUserData(DataSet ds)
    {
        if(ds != null)
        {
            UserAdapter.Update(ds);
            return ds;
        }
        else
        {
            return null;
        }
    }

    private void InitializeComponent()
    {
        this.UserDataset = new System.Data.DataSet();
        ((System.ComponentModel.ISupportInitialize)(this.UserDataset)).BeginInit();
        // 
        // UserDataset
        // 
        this.UserDataset.DataSetName = "NewDataSet";
        ((System.ComponentModel.ISupportInitialize)(this.UserDataset)).EndInit();

    }
}

This is the source code but when I am trying to access any of this method by making an object of Service1 class I am getting only two function in intellisense that are Equals() and ReferenceEquals(). any idea why am I getting this issue?

Can I see the code you are using to call this web service?

Hi, I am trying to call this web service in window application I am assigning generated dataset in web service to one of my dataset in windows application. The code is as follows

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Web.Services;
using System.Configuration.Assemblies;
using System.Xml;

namespace UserWindow
{
public partial class UserWindow : Form
{
public UserWindow()
{
InitializeComponent();
}

    private void LoadData\_Click(object sender, EventArgs e)
    {
        DataSet ds = new DataSet();
        ds = UserWebService1.Service1.(Here I am getting Reference, GenerateXMLMappings and EqualReference methods)
    }
}

}

Try this:

private void LoadData\_Click(object sender, EventArgs e)
{
    DataSet ds = new DataSet();
    UserWebService1.Service1 WebSrvc = new UserWebService1.Service1();
    ds = WebSrvc.YouFunctionHere;
}

Thanx Its working now but what was the fault in previous code when I am trying to call methods directly.

You must always unless create an instance of the class before you can use it. UNLESS it's a static object.
