Protected Function EncodeUrl (
	url As String
) As String

Parameters

url
Type: System.String

A string containing the URL to encode.

URL encoding of a character consists of a percent symbol (%), followed by the two-digit hexadecimal representation (case-insensitive) of the ISO-Latin code point for the character. The hexadecimal representation of a space is 20.

The following code example demonstrates how to call the EncodeUrl method to convert any spaces in the URL that is passed as a parameter in an AddAttribute method call.

' If an <anchor> element is rendered and an href
' attribute has not been defined, call the AddAttribute
' method to add an href attribute
' and set it to http://www.cohowinery.com.
' Use the EncodeUrl method to convert any spaces to %20.
If TagKey = HtmlTextWriterTag.A Then
    If Not IsAttributeDefined(HtmlTextWriterAttribute.Href) Then
        AddAttribute("href", EncodeUrl("http://www.cohowinery.com"))
    End If
End If
