HttpServerUtility::UrlEncode Method (String^, TextWriter^)

 

URL-encodes a string and sends the resulting output to a TextWriter output stream.

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

public:
void UrlEncode(
	String^ s,
	TextWriter^ output
)

Parameters

s
Type: System::String^

The text string to encode.

output
Type: System.IO::TextWriter^

The TextWriter output stream that contains the encoded string.

URL encoding ensures that all browsers will correctly transmit text in URL strings. Characters such as a question mark (?), ampersand (&), slash mark (/), and spaces might be truncated or corrupted by some browsers. As a result, these characters 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 HttpUtility::UrlEncode method at run time from an ASP.NET application. Internally, UrlEncode uses HttpUtility::UrlEncode to encode strings.

To encode or decode values outside of a web application, use the WebUtility class.

The following example encodes a string for transmission by HTTP. It encodes the string named TestString, which contains the text "This is a <Test String>.", and copies it into the string named EncodedString as "This+is+a+%3cTest+String%3e.".
