HtmlTextWriter::EncodeUrl Method (String^)

.NET Framework (current version)
 

Performs minimal URL encoding by converting spaces in the specified URL to the string "%20".

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

String^ EncodeUrl(
	String^ url
)

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.

C#
C++
VB
Copy 
// 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 )
{
   if (  !IsAttributeDefined( HtmlTextWriterAttribute::Href ) )
   {
      AddAttribute( "href", EncodeUrl( "http://www.cohowinery.com" ) );
   }
}
