WebUtility.UrlDecodeToBytes Method (Byte, Int32, Int32)
Converts an encoded byte array that has been encoded for transmission in a URL into a decoded byte array.
Assembly: System (in System.dll)
If characters such as blanks and punctuation are passed in an HTTP stream, they might be misinterpreted at the receiving end. URL encoding converts characters that are not allowed in a URL into equivalent hexadecimal escape sequences. The UrlEncodeToBytes method creates a URL-encoded byte array.
URL decoding replaces hexadecimal escape sequences with corresponding ASCII character equivalents. For example, when embedded in a block of URL-encoded text, the escape sequences %3c and %3e are decoded into the characters < and >.
