decodeURIComponent

public string decodeURIComponent(string uriComponent)

The decoded (unescaped) URI component.

Parameters

uriComponent

The URI component to decode.

Decodes an individual URI "component" such as:

• Query strings
• Protocol
• Hostname
• etc.

The decoding works by converting characters following the % escape character via UTF-8 decoding.

If the input URI component is invalid, System.Exceptions.InvalidURIException will be thrown. An example of an invalid URI component would be the % escape character being used in isolation without a full escape sequence.
