HttpUtility.UrlEncode Method
Converts a text string into a URL-encoded string.
Namespace: System.Windows.Browser
Assembly: System.Windows.Browser (in System.Windows.Browser.dll)
Parameters
- url
- Type: System.String
The text to URL-encode.
If characters such as blanks and punctuation are passed in an HTTP stream, they might be misinterpreted at the receiving end. URL encoding replaces characters that are not allowed in a URL with character-entity equivalents consisting of hexadecimal escape sequences. The converted string is expected to conform to the UTF-8 format.
URL encoding replaces all character codes except for letters, numbers, and the following punctuation characters:
-
- (minus sign)
-
_ (underscore)
-
. (period)
-
! (exclamation point)
-
* (asterisk)
-
' (single quotation mark)
-
( and ) (opening and closing parentheses)
For example, when embedded in a block of text to be transmitted in a URL, the characters < and > are encoded as %3c and %3e.
The UrlDecode method reverses the encoding.
