Converts a string to its unescaped representation.

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

Syntax

'Declaration
<SecuritySafeCriticalAttribute> _
Public Shared Function UnescapeDataString ( _
    stringToUnescape As String _
) As String

[SecuritySafeCriticalAttribute]
public static string UnescapeDataString(
    string stringToUnescape
)

Parameters

Return Value

Type: System.String
A String that contains the unescaped representation of stringToUnescape.

Exceptions

Exception Condition
ArgumentNullException

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

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.

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);
