Ejemplos

En el ejemplo siguiente se inserta un carácter de espacio en la cuarta posición de carácter (el carácter en el índice 3) de una cadena.

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'

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'

La siguiente aplicación de consola solicita a los usuarios que escriban uno o varios adjetivos para describir dos animales. A continuación, Insert llama al método para insertar el texto escrito por el usuario en una cadena.

using namespace System;

int main()
{
   String^ animal1 = "fox";
   String^ animal2 = "dog";
   String^ strTarget = String::Format( "The {0} jumps over the {1}.", animal1, animal2 );
   Console::WriteLine( "The original string is:{0}{1}{0}", Environment::NewLine, strTarget );
   Console::Write( "Enter an adjective (or group of adjectives) to describe the {0}: ==> ", animal1 );
   String^ adj1 = Console::ReadLine();
   Console::Write( "Enter an adjective (or group of adjectives) to describe the {0}: ==> ", animal2 );
   String^ adj2 = Console::ReadLine();
   adj1 = String::Concat( adj1->Trim(), " " );
   adj2 = String::Concat( adj2->Trim(), " " );
   strTarget = strTarget->Insert( strTarget->IndexOf( animal1 ), adj1 );
   strTarget = strTarget->Insert( strTarget->IndexOf( animal2 ), adj2 );
   Console::WriteLine( " {0}The final string is: {0} {1}", Environment::NewLine, strTarget );
}
// Output from the example might appear as follows:
//       The original string is:
//       The fox jumps over the dog.
//       
//       Enter an adjective (or group of adjectives) to describe the fox: ==> bold
//       Enter an adjective (or group of adjectives) to describe the dog: ==> lazy
//       
//       The final string is:
