URL-encodes the path section of a URL string and returns the encoded string.
Assembly: System.Web (in System.Web.dll)
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.
The following example URL-encodes a string and then sends it to a browser client. In this example, the string MyURL is encoded as "http%3a%2f%2fwww.contoso.com%2farticles.aspx?title = ASP.NET Examples".
