public:
System::String ^ Insert(int startIndex, System::String ^ value);public string Insert(int startIndex, string value);member this.Insert : int * string -> stringPublic Function Insert (startIndex As Integer, value As String) As StringParameter
- startIndex
- Int32
Posisi indeks berbasis nol dari penyisipan.
- value
- String
String yang akan disisipkan.
Mengembalikan
String baru yang setara dengan instans ini, tetapi dengan value disisipkan pada posisi startIndex.
Pengecualian
value adalah null.
startIndex negatif atau lebih besar dari panjang instans ini.
Contoh
Contoh berikut menyisipkan karakter spasi dalam posisi karakter keempat (karakter pada indeks 3) dari string.
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'
Aplikasi konsol berikut meminta pengguna untuk memasukkan satu atau beberapa kata sifat untuk menggambarkan dua hewan. Kemudian memanggil Insert metode untuk menyisipkan teks yang dimasukkan oleh pengguna ke dalam string.

' 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:
' The bold fox jumps over the lazy dog.
Keterangan
Jika startIndex sama dengan panjang instans ini, value ditambahkan ke akhir instans ini.
Note
Metode ini tidak mengubah nilai instans saat ini. Sebaliknya, ia mengembalikan string baru di mana value dimasukkan ke dalam instans saat ini.
Misalnya, nilai "abc".Insert(2, "XYZ") pengembalian adalah "abXYZc".
