Beispiele

Im folgenden Beispiel wird ein Leerzeichen an der vierten Zeichenposition (das Zeichen am Index 3) einer Zeichenfolge eingefügt.

using System;

public class Example
{
   public static void Main()
   {
      String original = "aaabbb";
      Console.WriteLine("The original string: '{0}'", original);
      String modified = original.Insert(3, " ");
      Console.WriteLine("The modified string: '{0}'", modified);
   }
}
// The example displays the following output:
//     The original string: 'aaabbb'
//     The modified string: 'aaa bbb'

let original = "aaabbb"
printfn $"The original string: '{original}'"
let modified = original.Insert(3, " ")
printfn $"The modified string: '{modified}'"
// The example displays the following output:
//     The original string: 'aaabbb'
//     The modified string: 'aaa bbb'

Public Module Example
   Public Sub Main()
      Dim original As String = "aaabbb"
      Console.WriteLine("The original string: '{0}'", original)
      Dim modified As String = original.Insert(3, " ")
      Console.WriteLine("The modified string: '{0}'", modified)
   End Sub
End Module
' The example displays the following output:
'     The original string: 'aaabbb'
'     The modified string: 'aaa bbb'
