HttpServerUtility.UrlEncode Method (String, TextWriter)
Assembly: System.Web (in system.web.dll)
The text string to encode.
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 System.Web.HttpUtility.UrlEncode method at run time from an ASP.NET application. Internally, UrlEncode uses System.Web.HttpUtility.UrlEncode to encode strings.
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.".
String TestString = "This is a <Test String>."; StringWriter writer = new StringWriter(); Server.UrlEncode(TestString, writer); String EncodedString = writer.ToString();
String testString = "This is a <Test String>."; StringWriter writer = new StringWriter(); get_Server().UrlEncode(testString, writer); String encodedString = writer.ToString();
