Namespace: System
Assembly: System (in system.dll)

public static string UnescapeDataString (

)
public static String UnescapeDataString (
	String stringToUnescape
)
public static function UnescapeDataString (
	stringToUnescape : String
) : String

Parameters

stringToUnescape

The string to unescape.

Return Value

The unescaped representation of stringToUnescape.

Exception typeCondition

ArgumentNullException

stringToUnescape is a null reference (Nothing in Visual Basic).

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);
