Encoder 构造函数

定义

命名空间:

System.Text

程序集:

System.Runtime.dll

Source:

Encoder.cs

初始化 Encoder 类的新实例。

protected:
 Encoder();

protected Encoder ();

Protected Sub New ()

示例

以下示例演示初始化新 Encoder 实例的两种方法。

using namespace System;
using namespace System::Text;
int main()
{
   
   // An Encoder is obtained from an Encoding.
   UnicodeEncoding^ uni = gcnew UnicodeEncoding;
   Encoder^ enc1 = uni->GetEncoder();
   
   // A more direct technique.
   Encoder^ enc2 = Encoding::Unicode->GetEncoder();
   
   // enc1 and enc2 seem to be the same.
   Console::WriteLine( enc1 );
   Console::WriteLine( enc2 );
   
   // Note that their hash codes differ.
   Console::WriteLine( enc1->GetHashCode() );
   Console::WriteLine( enc2->GetHashCode() );
}

/* This code example produces the following output.

System.Text.EncoderNLS
System.Text.EncoderNLS
54267293
18643596

*/

using System;
using System.Text;

class EncoderExample {
    public static void Main() {
        // An Encoder is obtained from an Encoding.
        UnicodeEncoding uni = new UnicodeEncoding();
        Encoder enc1 = uni.GetEncoder();

        // A more direct technique.
        Encoder enc2 = Encoding.Unicode.GetEncoder();

        // enc1 and enc2 seem to be the same.
        Console.WriteLine(enc1.ToString());
        Console.WriteLine(enc2.ToString());

        // Note that their hash codes differ.
        Console.WriteLine(enc1.GetHashCode());
        Console.WriteLine(enc2.GetHashCode());
    }
}

/* This code example produces the following output.

System.Text.EncoderNLS
System.Text.EncoderNLS
58225482

*/

Imports System.Text

Class EncoderExample
    
    Public Shared Sub Main()
        ' An Encoder is obtained from an Encoding.
        Dim uni As New UnicodeEncoding()
        Dim enc1 As Encoder = uni.GetEncoder()
        
        ' A more direct technique.
        Dim enc2 As Encoder = Encoding.Unicode.GetEncoder()
        
        ' enc1 and enc2 seem the same.
        Console.WriteLine(enc1.ToString())
        Console.WriteLine(enc2.ToString())
        
        ' Note that their hash codes differ.
        Console.WriteLine(enc1.GetHashCode())
        Console.WriteLine(enc2.GetHashCode())
    End Sub
End Class

注解

若要获取此类实现的实例，应用程序应使用 GetEncoder 实现的 Encoding 方法。
