HttpUtility.UrlEncode Method (Byte[], Int32, Int32)

Namespace:  System.Web
Assembly:  System.Web (in System.Web.dll)

public static string UrlEncode(
	byte[] bytes,
	int offset,
	int count
)

Parameters

bytes
Type: System.Byte[]

The array of bytes to encode.

offset
Type: System.Int32

The position in the byte array at which to begin encoding.

count
Type: System.Int32

The number of bytes to encode.

Return Value

Type: System.String
An encoded string.

The UrlEncode method can be used to encode the entire URL, including query-string values. 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".

You can encode a URL using with the UrlEncode method or the UrlPathEncode method. However, the methods return different results. The UrlEncode method converts each space character to a plus character (+). The UrlPathEncode method converts each space character into the string "%20", which represents a space in hexadecimal notation. Use the UrlPathEncode method when you encode the path portion of a URL in order to guarantee a consistent decoded URL, regardless of which platform or browser performs the decoding.
