Hi friend , here i have explained about Application object.
Introduction:
Application
object is used to store the information and access variables from any page in
the application. Application object is same as the Session object but only difference is that session
object is used only for particular user.Apllication object is same for all users once application object
is created that application is used through out
all the pages in application (like database connection) and we change
the application object one place those will changes in all the pages.
You can
create the application object in Global.asax file and access those variable in all
the pages.
Add the following code in Global.asax file :
<%@ Application Language="C#" %>
<script runat="server">
void Application_Start(object sender, EventArgs e)
{
// Code that runs on application startup
Application["UserID"] = "SureshDasari";
}
</script>
After
this write the following code in aspx page:
<html>
<head>
<title>Application Object Sample</title>
</head>
<body>
<form id="form1" runat="server">
<asp:Label id="lblText" runat="server"></asp:Label>
</form>
</body>
</html>
After that write the following code in .cs file:
public void
Page_Load(object sender, EventArgs e)
{
this.lblText.Text
= "UserName: " +
Application["UserID"] + "<br>";
}
