範例

下列範例會將字元轉換成其十六進位對等專案，並將它寫入主控台。

char testChar = 'e';
if ( Uri::IsHexDigit( testChar ) == true )
{
   Console::WriteLine( "'{0}' is the hexadecimal representation of {1}",
      testChar, Uri::FromHex( testChar ) );
}
else
{
   Console::WriteLine( "'{0}' is not a hex character", testChar );
}

String^ returnString = Uri::HexEscape( testChar );
Console::WriteLine( "The hexadecimal value of '{0}' is {1}", testChar, returnString );

char  testChar = 'e';
if (Uri.IsHexDigit(testChar) == true)
    Console.WriteLine("'{0}' is the hexadecimal representation of {1}", testChar, Uri.FromHex(testChar));
else
    Console.WriteLine("'{0}' is not a hexadecimal character", testChar);

string returnString = Uri.HexEscape(testChar);
Console.WriteLine("The hexadecimal value of '{0}' is {1}", testChar, returnString);

let testChar = 'e'
if Uri.IsHexDigit testChar then
    printfn $"'{testChar}' is the hexadecimal representation of {Uri.FromHex testChar}"
else
    printfn $"'{testChar}' is not a hexadecimal character"

let returnString = Uri.HexEscape testChar
printfn $"The hexadecimal value of '{testChar}' is {returnString}"

Dim testChar As Char = "e"c
If Uri.IsHexDigit(testChar) = True Then
    Console.WriteLine("'{0}' is the hexadecimal representation of {1}", testChar, Uri.FromHex(testChar))
Else
    Console.WriteLine("'{0}' is not a hexadecimal character", testChar)
End If 
Dim returnString As String = Uri.HexEscape(testChar)
Console.WriteLine("The hexadecimal value of '{0}' is {1}", testChar, returnString)
