I am writing simple instructions with snapshots for a good understanding and for your use in your projects.

Let's create our web service first for sending a DataSet and DataTable.

Step 1 : Open Visual Studio then select "File" -> "New" -> "Project..." then provide a project name.



I have provided the project name WebServicewithpassingliat.

After adding the project name we will just create a new web service.

Step 2 : Let us add a web service for sending a DataSet and DataTable.

For adding the web service right-click on the solution then select Add > Add New Item then select Web Service then click the Add button.



Step 3 : After adding the web service you will see a WebMethod with the name Helloworld; just remove it.

And create a new WebMethod of type DataSet and name it MobileDataset() and add another Web Method of type DataTable and name it MobileDatatable().

For reference see the following image:


  1. DataSet Code Snippet.

    And this Webmethod will return a DataSet.

  2. DataTable code snippet.


And this Webmethod will return a DataTable.

Just run your application now.

You will see the same screen that is given below.



Now just copy this URL.

http://localhost:2157/Service1.asmx

Step 4 : Let's create another project then it will consume this list.

Open Visual Studio then select "File" -> "New" -> "Project..." then provide a project name.

Here I am using the name WebApplication2.



After creating it you will see your solution like the following:



Step 5 : Then just right-click on the solution and select Add Web Reference.



After selecting Add Web Reference a new dialog will pop up asking for an address.



Step 6 : Just paste the preceding address that you copied.

http://localhost:2157/Service1.asmx



After adding the URL just click the Add Reference button.

Now your solution will look like this.



Now we have completed the adding of the service.

Step 7: Now we just want to use this service.

We have a default page that is created by default.

On the page load of that page I have created a couple of methods with the names:

  1. GET_DATASET(); // For Getting the Dataset
  2. GET_DATATABLE(); // for Getting the DataTable

Code of the default page:

  1. using System;
  2. using System.Collections.Generic;
  3. using System.Linq;
  4. using System.Web;
  5. using System.Web.UI;
  6. using System.Web.UI.WebControls;
  7. using System.Data;
  8. using WebApplication2.localhost;
  9. using System.Text;
  11. namespace WebApplication2
  12. {
  13. public partial class _Default : System.Web.UI.Page
  14. {
  15. protected void Page_Load(object sender, EventArgs e)
  16. {
  17. GET_DATASET();
  18. GET_DATATABLE();
  20. }
  22. public void GET_DATATABLE()
  23. {
  24. localhost.Service1 mo = new WebApplication2.localhost.Service1();
  25. DataTable dt = mo.MobileDatatable();
  26. GridView1.DataSource = dt;
  27. GridView1.DataBind();
  28. }
  30. public void GET_DATASET()
  31. {
  32. localhost.Service1 mo = new WebApplication2.localhost.Service1();
  33. DataSet ds = mo.MobileDataset();
  34. GridView2.DataSource = ds;
  35. GridView2.DataBind();
  36. }
  37. }
  38. }

Namespace

  1. using WebApplication2.localhost; // is the namespace for accessing service objects

In this code I have created an object of web service that we have added.

  1. localhost.Service1 mo = new WebApplication2.localhost.Service1();

After creating an object I have passed an object to the DataSet.

  1. localhost.Service1 mo = new WebApplication2.localhost.Service1();
  2. DataSet ds = mo.MobileDataset();

For the DataTable I have created an object. I have passed an object to the DataTable.

  1. localhost.Service1 mo = new WebApplication2.localhost.Service1();
  2. DataTable dt = mo.MobileDatatable();

Design of Default page

  1. <html xmlns="http://www.w3.org/1999/xhtml">
  2. <head runat="server">
  3. <title></title>
  4. </head>
  5. <body>
  6. <form id="form1" runat="server">
  7. <div>
  8. <asp:GridView ID="GridView1" runat="server">
  9. </asp:GridView>
  10. <br />
  11. <asp:GridView ID="GridView2" runat="server">
  12. </asp:GridView>
  13. </div>
  14. </form>
  15. </body>
  16. </html>

I have only added 2 GridViews for displaying data of both the DataTable and DataSet.

After doing that, just run the application and check it.

Here is the output:



Now we have successfully transferred a DataTable and DataSet.
