Decoder 建構函式

定義

命名空間:

System.Text

組件:

System.Runtime.dll

來源:

Decoder.cs

初始化 Decoder 類別的新執行個體。

protected:
 Decoder();

protected Decoder ();

Protected Sub New ()

範例

下列範例示範兩種初始化新 Decoder 實例的技術。

using namespace System;
using namespace System::Text;
int main()
{
   
   // A Decoder is obtained from an Encoding.
   UnicodeEncoding^ uni = gcnew UnicodeEncoding;
   Decoder^ dec1 = uni->GetDecoder();
   
   // A more direct technique.
   Decoder^ dec2 = Encoding::Unicode->GetDecoder();
   
   // dec1 and dec2 seem to be the same.
   Console::WriteLine( dec1 );
   Console::WriteLine( dec2 );
   
   // Note that their hash codes differ.
   Console::WriteLine( dec1->GetHashCode() );
   Console::WriteLine( dec2->GetHashCode() );
}

/* This code example produces the following output.

System.Text.UnicodeEncoding+Decoder
System.Text.UnicodeEncoding+Decoder
54267293

*/

using System;
using System.Text;

class EncoderExample {
    public static void Main() {
        // A Decoder is obtained from an Encoding.
        UnicodeEncoding uni = new UnicodeEncoding();
        Decoder dec1 = uni.GetDecoder();

        // A more direct technique.
        Decoder dec2 = Encoding.Unicode.GetDecoder();

        // dec1 and dec2 seem to be the same.
        Console.WriteLine(dec1.ToString());
        Console.WriteLine(dec2.ToString());

        // Note that their hash codes differ.
        Console.WriteLine(dec1.GetHashCode());
        Console.WriteLine(dec2.GetHashCode());
    }
}

/* This code example produces the following output.

System.Text.UnicodeEncoding+Decoder

Imports System.Text

Class EncoderExample
    
    Public Shared Sub Main()
        ' A Decoder is obtained from an Encoding.
        Dim uni As New UnicodeEncoding()
        Dim dec1 As Decoder = uni.GetDecoder()
        
        ' A more direct technique.
        Dim dec2 As Decoder = Encoding.Unicode.GetDecoder()
        
        ' dec1 and dec2 seem to be the same.
        Console.WriteLine(dec1.ToString())
        Console.WriteLine(dec2.ToString())
        
        ' Note that their hash codes differ.
        Console.WriteLine(dec1.GetHashCode())
        Console.WriteLine(dec2.GetHashCode())
    End Sub
End Class

備註

若要取得這個類別的實作實例，應用程式應該使用 GetDecoder 實作的 Encoding 方法。
