ASP.NET Server Side tutorials

The Server Object

  • The Server object provides access to properties and methods on the server. Much of functionality it provides is simply functionality the web server itself uses in the normal processing of client requests and server responses.

  • The Server object in Asp.Net is an instance of the System.Web.HttpServerUtility class. The HttpServerUtility class provides numerous properties and methods to perform various jobs.

 

Syntax:

public sealed class HttpServerUtility

Properties and Methods of the Server object:

  • The methods and properties of the HttpServerUtility class are exposed through the intrinsic Server object provided by ASP.NET.

  • The following table provides a list of the properties of the Server object:

 

Properties

Description

MachineName

Gets the server's computer name

ScriptTimeOut

Gets and sets the request time-out value in seconds.

 

The following table provides a list of some important methods of the Server object:

Method

Description

ClearError

Clears the previous exception

CreateObject(String)

Creates a server instance of a COM object identified by the object's programmatic identifier (ProgID)

CreateObject(Type)

Creates a server instance of a COM object identified by the object's type

Equals(Object)

Determines whether the specified object is equal to the current object

Execute(String)

Executes the handler for the specified virtual path in the context of the current request

Execute(String, Boolean)

Executes the handler for the specified virtual path in the context of the current request and specifies whether to clear the QueryString and Form collections

GetLastError

Returns the previous exception

GetType

Gets the Type of the current instance

HtmlEncode

Changes an ordinary string into a string with legal HTML characters

HtmlDecode

Converts an Html string into an ordinary string

ToString

Returns a String that represents the current Object

Transfer(String)

For the current request, terminates execution of the current page and starts execution of a new page by using the specified URL path of the page.

UrlDecode

Converts an URL string into an ordinary string

UrlEncodeToken

Works same as UrlEncode, but on a byte array that contains Base64-encoded data

UrlDecodeToken

Works same as UrlDecode, but on a byte array that contains Base64-encoded data

MapPath

Returns the physical file path that corresponds to the specified virtual path on the Web server

Transfer

Transfers execution to another web page in the current application


Example:

  • The HtmlEncode method helps ensure that any user-supplied string input will be rendered as static text in browsers instead of executable script or HTML elements.

  • The UrlEncode method encodes URLs so that they are correctly transmitted in the HTTP stream.

SeverObjectExample.aspx.cs Code:

 

 

Following example demonstrates how to use the ASP.NET HtmlEncode method and the UrlEncode method of theHttpServerUtility class.
