StringBuilder.Clear 메서드

정의

현재 StringBuilder 인스턴스에서 모든 문자를 제거합니다.Removes all characters from the current StringBuilder instance.

public:
 System::Text::StringBuilder ^ Clear();
public System.Text.StringBuilder Clear ();
member this.Clear : unit -> System.Text.StringBuilder
Public Function Clear () As StringBuilder

반환

Length가 0인 개체입니다.An object whose Length is 0 (zero).

예제

다음 예제에서는 문자열을 사용 하 여 StringBuilder 개체를 인스턴스화하고 Clear 메서드를 호출한 다음 새 문자열을 추가 합니다.The following example instantiates a StringBuilder object with a string, calls the Clear method, and then appends a new string.

using System;
using System.Text;

public class Class1
{
   public static void Main()
   {
      StringBuilder sb = new StringBuilder("This is a string.");
      Console.WriteLine("{0} ({1} characters)", sb.ToString(), sb.Length);
      
      sb.Clear();
      Console.WriteLine("{0} ({1} characters)", sb.ToString(), sb.Length);

      sb.Append("This is a second string.");
      Console.WriteLine("{0} ({1} characters)", sb.ToString(), sb.Length);
   }
}
// The example displays the following output:
//       This is a string. (17 characters)
//        (0 characters)
//       This is a second string. (24 characters)
Imports System.Text

Module Example
   Public Sub Main()
      Dim sb As New StringBuilder("This is a string.")
      Console.WriteLine("{0} ({1} characters)", sb.ToString(), sb.Length)
      
      sb.Clear()
      Console.WriteLine("{0} ({1} characters)", sb.ToString(), sb.Length)

      sb.Append("This is a second string.")
      Console.WriteLine("{0} ({1} characters)", sb.ToString(), sb.Length)
   End Sub            
End Module
' The example displays the following output:
'       This is a string. (17 characters)
'        (0 characters)
'       This is a second string. (24 characters)

설명

Clear은 현재 인스턴스의 Length 속성을 0 (영)으로 설정 하는 것과 동일한 편리한 메서드입니다.Clear is a convenience method that is equivalent to setting the Length property of the current instance to 0 (zero).
