Parameters

str

The text to encode.

Return Value

An encoded string.

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 character-entity equivalents; URL decoding reverses the encoding. For example, when embedded in a block of text to be transmitted in a URL, the characters < and > are encoded as %3c and %3e.

Add information about the default encoding      Paulo Morgado   |   Edit   |   Show History

This method uses the default encoding of utf-8.

Calling:

HttpUtility.UrlEncode("some text")

is the same as calling:

HttpUtility.UrlEncode("some text", Encoding.UTF8)
