HttpServerUtility.UrlEncode Method (String)

URL-encodes a string and returns the encoded string.

Namespace: System.Web
Assembly: System.Web (in system.web.dll)

public string UrlEncode (
	string s
)
public String UrlEncode (
	String s
)
public function UrlEncode (
	s : String
) : String

Parameters

s

The text to URL-encode.

Return Value

The URL-encoded text.

URL encoding ensures that all browsers will correctly transmit text in URL strings. Characters such as ?, &, /, and spaces might be truncated or corrupted by some browsers, so those must be encoded in <a> tags or in query strings where the strings can be re-sent by a browser in a request string.

UrlEncode is a convenient way to access the System.Web.HttpUtility.UrlEncode method at run time from an ASP.NET Web application. Internally, UrlEncode uses System.Web.HttpUtility.UrlEncode to encode strings.

The following code example URL-encodes a string before sending it to a browser client. In this example, the string MyURL is encoded as "http%3a%2f%2fwww.contoso.com%2farticles.aspx%3ftitle+%3d+ASP.NET+Examples".

String MyURL;
MyURL = "http://www.contoso.com/articles.aspx?title = ASP.NET Examples";

Response.Write( "<A HREF = " + Server.UrlEncode(MyURL) +  "> ASP.NET Examples <br>" );
   

String myURL;
myURL = "http://www.contoso.com/articles.aspx?title = ASP.NET Examples";
get_Response().Write(("<A HREF = " + get_Server().UrlEncode(myURL)
    + "> ASP.NET Examples <br>"));

var myURL : String
myURL = "http://www.contoso.com/articles.aspx?title = ASP.NET Examples"

Response.Write( "<A HREF = " + Server.UrlEncode(myURL) + "> ASP.NET Examples <br>")
