You should use this method with care. Unescaping a string that has been previously unescaped can lead to ambiguities and errors.
Many Web browsers escape spaces inside of URIs into plus ("+") characters; however, the UnescapeDataString method does not convert plus characters into spaces because this behavior is not standard across all URI schemes.
The following code example unescapes a URI, and then converts any plus characters ("+") into spaces.
String DataString = Uri.UnescapeDataString(".NET+Framework");
Console.WriteLine("Unescaped string: {0}", DataString);
String PlusString = DataString.Replace('+',' ');
Console.WriteLine("plus to space string: {0}", PlusString);
