        WebService data = new WebService();
        DataSet allData = new DataSet();

        allData = data.GetResultThroughQuery(ReportName, DatasourceID);
    }
}

C#

 using System;
using System.Linq;
using System.Web.Services;
using System.Collections.Generic;

using System.Data;
using System.Data.SqlClient;

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
// [System.Web.Script.Services.ScriptService]
public class Service : System.Web.Services.WebService
{
    String ConStr = "Server=192.168.241.2; Database=BIModel; User Id=Sa; password=Nopass123";
   
    
    public Service () {
        
        
                       }


    [WebMethod]
    public DataSet GetResultThroughQuery(string ReportName, string DatasourceID)
    {
        DataSet dataSet=new DataSet();



        return dataSet;
    }
    
}

We get a error message like that: 'System.Web.Services.WebService' does not contain a definition for 'GetResultThroughQuery' and no extension method 'GetResultThroughQuery' accepting a first argument of type 'System.Web.Services.WebService' could be found (are you missing a using directive or an assembly reference?)

Have you inserted service refrence in your solution ?
If not add to your solution and make change in webconfig file as
eg:
my webservice method:

C#

[WebMethod]
       public int insertRecord( string sName, string sAge, string sSalary, string sCountry, string sCity)
       {
           var con = new SqlConnection(ConnectionState());
           con.Open();

           var cmd = new SqlCommand("Insert into EMaster(Name,Age, Salary, Country,City) values( '" + sName + "','" + sAge + "','" + sSalary + "','" + sCountry + "','"+ sCity + "')", con);
           int row = cmd.ExecuteNonQuery();
           return row;
       }

and web.config:

XML

<applicationSettings>
  <EmployeeDetails.Properties.Settings>
   <setting name="EmployeeDetails_localhost_Service1" serializeAs="String">
    <value>http://localhost:50656/Service1.asmx</value>
   </setting>
  </EmployeeDetails.Properties.Settings>
 </applicationSettings>

and in code behnd files use like this

protected void Addbutton_Click(object sender, EventArgs e)
      {
          txtid.Enabled = false;
          localhost.Service1 dbws = new localhost.Service1();
          if ((txtName.Text == "") || (txtage.Text == "") || (txtsalary.Text == "") || (txtcountry.Text == "") || (txtcity.Text == ""))
          { Response.Write("<script>alert('Record not insert-Rows Cannot be null');</script>"); }
          else
          {
              int row = dbws.insertRecord(txtName.Text, txtage.Text, txtsalary.Text, txtcountry.Text, txtcity.Text);
              if (row > 0)
              {
                  Response.Write("<script>alert('Record insert successfuly');</script>");
                  txtid.Text=txtName.Text = txtage.Text = txtsalary.Text = txtcountry.Text = txtcity.Text = "";
                  getId();
                  FillGrid();
                  ddlSelect_SelectedIndexChanged(sender, e);

              }
              else { Response.Write("<script>alert('Record not insert');</script>"); }
          }

      }

here service1 is my webservice name.
