StringWriter-Konstruktor ()

Initialisiert eine neue Instanz der StringWriter-Klasse.

Namespace: System.IO
Assembly: mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public Sub New
'Usage
Dim instance As New StringWriter

public StringWriter ()

public:
StringWriter ()

public StringWriter ()

public function StringWriter ()

Hinweise

Es wird automatisch ein neuer StringBuilder erstellt und dem neuen StringWriter zugeordnet.

In der folgenden Tabelle sind Beispiele für andere typische oder verwandte E/A-Aufgaben aufgeführt.

Beispiel

Das folgende Codebeispiel veranschaulicht das Erstellen einer Zeichenfolge mithilfe der StringWriter-Klasse.

Imports Microsoft.VisualBasic
Imports System
Imports System.IO
Imports System.Text

Public Class StrWriter

    Shared Sub Main()

        Dim strWriter As StringWriter = new StringWriter()

        ' Use the three overloads of the Write method that are 
        ' overridden by the StringWriter class.
        strWriter.Write("file path characters are: ")
        strWriter.Write( _
            Path.InvalidPathChars, 0, Path.InvalidPathChars.Length)
        strWriter.Write("."C)

        ' Use the underlying StringBuilder for more complex 
        ' manipulations of the string.
        strWriter.GetStringBuilder().Insert(0, "Invalid ")

        Console.WriteLine("The following string is {0} encoded." _
            & vbCrLf & "{1}", _
