Insert Data With Typed Dataset (XSD) Via WCF

Introduction

This article demonstrates an interesting and very useful concept in typed dataset.

Question: What is insert data with typed dataset (XSD) via WCF?

In simple terms "It provides the ability to insert data from a DB using a typed dataset using a WCF Service".

Step 1: Create a new web application

Step 2: Create a new WCF service application

Step 3: Adding a new typed dataset

Step 4: The complete code of IService1.cs is as in the following:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Runtime.Serialization;

using System.ServiceModel;

using System.ServiceModel.Web;

using System.Text;

namespace WCFService

{

// NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.

[ServiceContract]

public interface IService1

{

[OperationContract]EmployeeDS.tblEmployeeDataTable GetAllEmployees();

[OperationContract]

void PutEmployee(string a, string b, int c);

}

}

Step 5: The complete code of Service1.svc.cs is as in the following:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Runtime.Serialization;

using System.ServiceModel;

using System.ServiceModel.Web;

using System.Text;

namespace WCFService

{

// NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service1" in code, svc and config file together.

public class Service1 : IService1

{

public EmployeeDS.tblEmployeeDataTable GetAllEmployees()

{

EmployeeDS.tblEmployeeDataTable objEmployeeTable = objAdapter.GetData();

return objEmployeeTable;

}

public void PutEmployee(string a, string b, int c)

{

objAdapter.Insert(a, b, c);

}

#region Instance Membersreadonly EmployeeDSTableAdapters.tblEmployeeTableAdapter objAdapter = new EmployeeDSTableAdapters.tblEmployeeTableAdapter();

#endregion

}

}

Step 6: Adding a service reference

Step 7: The complete code of WebForm1.aspx is as in the following:

</td>

</tr>

<tr>

<asp:Button ID="Button1" runat="server" Text="Insert Data" OnClick="Button1_Click"

BackColor="Orange" Font-Bold="true" /><br />

<br />

</td>

</tr>

<br />

<tr>

<asp:Label ID="Label5" runat="server" ForeColor="Red" Font-Bold="true"></asp:Label>

</td>

</tr>

</table>

</center>

</div>

</form>

</body>

</html>

Step 8: The complete code of WebForm1.aspx.cs is as in the following:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

using InsertData_XSD_WCF.ServiceReference1;namespace InsertData_XSD_WCF

{

public partial class WebForm1 : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

}

protected void Button1_Click(object sender, EventArgs e)

{

if (string.IsNullOrEmpty(TextBox1.Text) || string.IsNullOrEmpty(TextBox2.Text) || string.IsNullOrEmpty(TextBox3.Text))

{

Label5.Text = "Please Enter Some Values";

Label5.ForeColor = System.Drawing.Color.Red;

}

else

{

objClient.PutEmployee(TextBox1.Text, TextBox2.Text, int.Parse(TextBox3.Text));

GridView1.DataSource = objClient.GetAllEmployees();

GridView1.DataBind();

Label5.Text = "Records Inserted Successfully";

Label5.ForeColor = System.Drawing.Color.Green;

TextBox1.Text = string.Empty;

TextBox2.Text = string.Empty;

TextBox3.Text = string.Empty;

}

#region Instance MembersService1Client objClient = new Service1Client();

#endregion

}

}

Step 9: The output of the application is as in the following:

Step 10: The inserted data output of the application is as in the following:
