예제

다음 예제에서는 클래스에서 정의한 많은 메서드를 호출하는 방법을 보여 줍니다 StringBuilder .

using System;
using System.Text;

public sealed class App
{
    static void Main()
    {
        // Create a StringBuilder that expects to hold 50 characters.
        // Initialize the StringBuilder with "ABC".
        StringBuilder sb = new StringBuilder("ABC", 50);

        // Append three characters (D, E, and F) to the end of the StringBuilder.
        sb.Append(new char[] { 'D', 'E', 'F' });

        // Append a format string to the end of the StringBuilder.
        sb.AppendFormat("GHI{0}{1}", 'J', 'k');

        // Display the number of characters in the StringBuilder and its string.
        Console.WriteLine("{0} chars: {1}", sb.Length, sb.ToString());

        // Insert a string at the beginning of the StringBuilder.
        sb.Insert(0, "Alphabet: ");

        // Replace all lowercase k's with uppercase K's.
        sb.Replace('k', 'K');

        // Display the number of characters in the StringBuilder and its string.
        Console.WriteLine("{0} chars: {1}", sb.Length, sb.ToString());
    }
}

// This code produces the following output.
//
// 11 chars: ABCDEFGHIJk
// 21 chars: Alphabet: ABCDEFGHIJK

open System.Text

// Create a StringBuilder that expects to hold 50 characters.
// Initialize the StringBuilder with "ABC".
let sb = StringBuilder("ABC", 50)

// Append three characters (D, E, and F) to the end of the StringBuilder.
sb.Append [| 'D'; 'E'; 'F' |] |> ignore

// Append a format string to the end of the StringBuilder.
sb.AppendFormat("GHI{0}{1}", 'J', 'k') |> ignore

// Display the number of characters in the StringBuilder and its string.
printfn $"{sb.Length} chars: {sb}"

// Insert a string at the beginning of the StringBuilder.
sb.Insert(0, "Alphabet: ") |> ignore

// Replace all lowercase k's with uppercase K's.
sb.Replace('k', 'K') |> ignore

// Display the number of characters in the StringBuilder and its string.
printfn $"{sb.Length} chars: {sb}"

// This code produces the following output.

설명

이 API에 대한 자세한 내용은 StringBuilder에 대한 추가 API 비고를 참조하세요.

호출자 참고

.NET Core 및 .NET Framework 4.0 이상 버전에서는 StringBuilder(Int32, Int32) 생성자를 호출하여 StringBuilder 개체를 인스턴스화할 때 StringBuilder 인스턴스의 길이와 용량이 MaxCapacity 속성 값을 초과하여 증가할 수 있습니다. 이 문제는 작은 문자열을 추가하기 위해 메서드를 Append(String)AppendFormat(String, Object) 호출할 때 특히 발생할 수 있습니다.
