The Server object can be considered as an instance of the System.Web.HttpServerUtility class. Server object of ASP.NET is related to the manipulation of utility functions or server tasks on the server.

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

Constructor

Constructor Description
this.httpContext.Server Initializes a reference to HttpServerUtilityBase
HttpContext.Current.Server Initializes an instance of HttpServerUtility object.

Methods

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.
CreateObjectFromClsid(String) Creates a server instance of a COM object identified by the object's class identifier (CLSID).
Equals(Object) Determines whether the specified object is equal to the current object. (Inherited from Object)
Execute(IHttpHandler, TextWriter, Boolean) Executes the handler for the specified virtual path in the context of the current request. A TextWriter captures output from the executed handler and a Boolean parameter specifies whether to clear the QueryString and Form collections.
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.
Execute(String, TextWriter) Executes the handler for the specified virtual path in the context of the current request. A TextWriter captures output from the executed handler.
Execute(String, TextWriter, Boolean) Executes the handler for the specified virtual path in the context of the current request. A TextWriter captures output from the page and a Boolean parameter specifies whether to clear the QueryString and Form collections.
GetHashCode() Serves as the default hash function. (Inherited from Object)
GetLastError() Returns the previous exception.
GetType() Gets the Type of the current instance. (Inherited from Object)
HtmlDecode(String) Decodes an HTML-encoded string and returns the decoded string.
HtmlDecode(String, TextWriter) Decodes an HTML-encoded string and sends the resulting output to a TextWriter output stream.
HtmlEncode(String) HTML-encodes a string and returns the encoded string.
HtmlEncode(String, TextWriter) HTML-encodes a string and sends the resulting output to a TextWriter output stream.
MapPath(String) Returns the physical file path that corresponds to the specified virtual path.
MemberwiseClone() Creates a shallow copy of the current Object. (Inherited from Object)
ToString() Returns a string that represents the current object. (Inherited from Object)
Transfer(IHttpHandler, Boolean) Terminates execution of the current page and starts execution of a new request by using a custom HTTP handler that implements the IHttpHandler interface and specifies whether to clear the QueryString and Form collections.
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.
Transfer(String, Boolean) Terminates execution of the current page and starts execution of a new page by using the specified URL path of the page. Specifies whether to clear the QueryString and Form collections.
TransferRequest(String) Performs an asynchronous execution of the specified URL.
TransferRequest(String, Boolean) Performs an asynchronous execution of the specified URL and preserves query string parameters.
TransferRequest(String, Boolean, String, NameValueCollection) Performs an asynchronous execution of the specified URL using the specified HTTP method and headers.
TransferRequest(String, Boolean, String, NameValueCollection, Boolean) Performs an asynchronous execution of the specified URL using the specified HTTP method, headers, and path, and optionally preserves form values and the user identity.
UrlDecode(String) URL-decodes a string and returns the decoded string.
UrlDecode(String, TextWriter) Decodes an HTML string received in a URL and sends the resulting output to a TextWriter output stream.
UrlEncode(String) URL-encodes a string and returns the encoded string.
UrlEncode(String, TextWriter) URL-encodes a string and sends the resulting output to a TextWriter output stream.
UrlPathEncode(String) Do not use; intended only for browser compatibility. Use UrlEncode(String).
UrlTokenDecode(String) Decodes a URL string token to its equivalent byte array using base 64 digits.
UrlTokenEncode(Byte[]) Encodes a byte array into its equivalent string representation using base 64 digits, which is usable for transmission on the URL.

Properties

Property Description
MachineName Gets the server's computer name.
ScriptTimeout Gets or sets the request time-out value in seconds.
