NoteNote:

The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: UI. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

This method can be used to reacquire the standard output stream after it has been changed by the SetIn method.

The following code example illustrates the use of the OpenStandardInput property.

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));
    }
}
