public static string UnescapeDataString (string stringToUnescape);

static member UnescapeDataString : string -> string

Public Shared Function UnescapeDataString (stringToUnescape As String) As String

Examples

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);

let DataString = Uri.UnescapeDataString ".NET+Framework"
printfn $"Unescaped string: {DataString}"

let PlusString = DataString.Replace('+',' ')
printfn $"plus to space string: {PlusString}"

Remarks

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.
