Introduction
In this blog we will see how to perform inner join using linq to sql.
Step 1: Create asp.net web application
Webform1.aspx
- <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="InnerJoin_LINQtoSQL.WebForm1" %>
-
- <!DOCTYPE html>
-
- <html xmlns="http://www.w3.org/1999/xhtml">
- <head runat="server">
- <title></title>
- </head>
- <body>
- <form id="form1" runat="server">
- <div>
- <asp:GridView ID="GridView1" runat="server"></asp:GridView>
- </div>
- </form>
- </body>
- </html>
Webform1.aspx.cs
- using System;
- using System.Collections.Generic;
- using System.Linq;
- using System.Web;
- using System.Web.UI;
- using System.Web.UI.WebControls;
-
- namespace InnerJoin_LINQtoSQL
- {
- public partial class WebForm1 : System.Web.UI.Page
- {
- DataClasses1DataContext objContext = new DataClasses1DataContext();
- protected void Page_Load(object sender, EventArgs e)
- {
- var query = from r in objContext.Employees
- join s in objContext.Departments
- on r.DeptId equals s.DeptId
- select new
- {
- FirstName = r.FirstName
- ,LastName = r.LastName
- ,Department = s.DeptName
- };
-
- GridView1.DataSource = query;
- GridView1.DataBind();
- }
- }
- }
Output of the application looks like this
