示例

下面的示例演示了该方法的使用 OpenStandardInput 。

using System;
using System.Text;
using System.IO;

public class Decoder {
    public static void Main() {
        Stream inputStream = Console.OpenStandardInput();
        byte[] bytes = new byte[100];
        Console.WriteLine("To decode, type or paste the UTF7 encoded string and press enter:");
        Console.WriteLine("(Example: \"M+APw-nchen ist wundervoll\")");
        int outputLength = inputStream.Read(bytes, 0, 100);
        char[] chars = Encoding.UTF7.GetChars(bytes, 0, outputLength);
        Console.WriteLine("Decoded string:");
        Console.WriteLine(new string(chars));
    }
}

open System
open System.Text

let inputStream = Console.OpenStandardInput()
let bytes = Array.zeroCreate<byte> 100
Console.WriteLine "To decode, type or paste the UTF7 encoded string and press enter:"
Console.WriteLine "(Example: \"M+APw-nchen ist wundervoll\")"
let outputLength = inputStream.Read(bytes, 0, 100)
let chars = Encoding.UTF7.GetChars(bytes, 0, outputLength)
Console.WriteLine "Decoded string:"
Console.WriteLine(string chars)

Imports System.Text
Imports System.IO

Public Class Decoder
   Public Shared Sub Main()
      Dim inputStream As Stream = Console.OpenStandardInput()
      Dim bytes(100) As Byte
      Console.WriteLine("To decode, type or paste the UTF7 encoded string and press enter:")
      Console.WriteLine("(Example: ""M+APw-nchen ist wundervoll"")")
      Dim outputLength As Integer = inputStream.Read(bytes, 0, 100)
      Dim chars As Char() = Encoding.UTF7.GetChars(bytes, 0, outputLength)
      Console.WriteLine("Decoded string:")
      Console.WriteLine(New String(chars))
   End Sub
End Class
