What is the role of the Global.asax file?

The Global.asax file, also known as the ASP.NET application file, is used to create application and session-level events and objects in an ASP.NET Web application. It is an optional file that contains code for responding to application-level events, such as Application_Start, Application_End, Session_Start, Session_End, and Application_Error.

Example:

void Application_Start(object sender, EventArgs e)
{
// Code that runs on application startup
}

void Application_End(object sender, EventArgs e)
{
// Code that runs on application shutdown
}

void Application_Error(object sender, EventArgs e)
{
// Code that runs when an unhandled error occurs
}

void Session_Start(object sender, EventArgs e)
{
// Code that runs when a new session is started
}

void Session_End(object sender, EventArgs e)
{
// Code that runs when a session ends.
// Note: The Session_End event is raised only when the sessionstate mode
// is set to InProc in the Web.config file. If session mode is set to StateServer
// or SQLServer, the event is not raised.
}

The Global.asax file, also known as the ASP.NET application file, is an optional file used by ASP.NET applications to respond to application-level events, such as Application_Start, Application_End, Session_Start, and Session_End. This file is used to define application-level and session-level events, as well as to configure the application.

Example:

void Application_Start(object sender, EventArgs e)
{
// Code that runs on application startup
}
void Application_End(object sender, EventArgs e)
{
// Code that runs on application shutdown
}
void Session_Start(object sender, EventArgs e)
{
// Code that runs when a new session is started
}
void Session_End(object sender, EventArgs e)
{
// Code that runs when a session ends
}

The Global.asax file is an optional file used to declare application and session level events for an ASP.NET application. It is also known as the ASP.NET application file. The Global.asax file is used to handle application-level events and session-level events raised by ASP.NET or by HttpModules.

Example:

void Application_Start(object sender, EventArgs e)
{
// Code that runs on application startup
}

void Application_End(object sender, EventArgs e)
{
// Code that runs on application end
}

void Application_Error(object sender, EventArgs e)
{
// Code that runs when an unhandled error occurs
}

void Session_Start(object sender, EventArgs e)
{
// Code that runs when a new session is started
}

void Session_End(object sender, EventArgs e)
{
// Code that runs when a session ends
}

What is the role of Global.asax in ASP.NET?

The Global.asax file, also known as the ASP.NET application file, is an optional file that contains code for responding to application-level events raised by ASP.NET or by HttpModules. The Global.asax file resides in the root directory of an ASP.NET-based application.

The Global.asax file is parsed and compiled into a dynamically generated .NET Framework class derived from the HttpApplication base class. The Global.asax file can contain application-level event handlers.

Example:

The following example shows a Global.asax file with an Application_Start event handler. The Application_Start event handler is called when a new user visits the application for the first time.

void Application_Start(object sender, EventArgs e)
{
// Code that runs on application startup
// Create a new database connection
string connectionString = “data source=localhost;initial catalog=MyDatabase;Integrated Security=SSPI;”;
SqlConnection myConnection = new SqlConnection(connectionString);

// Open the connection
myConnection.Open();
}
