如何禁用Console.WriteLine等输出

又想到一个靠谱点的方法，不过调用会有些麻烦，参考下面的代码。

class ConsoleOut : TextWriter
{

private ConsoleOut(TextWriter output)
{
_out = output;
}

private TextWriter _out;

public override Encoding Encoding
{
get { return _out.Encoding; }
}

public override void Write(char value)
{
if (__outputEnabled)
_out.Write(value);
}

private static ConsoleOut __instance;

public static void Install()
{
if (__instance == null)
{
__instance = new ConsoleOut(Console.Out);
Console.SetOut(__instance);
}
}

private static bool __outputEnabled;

public static bool OutputEnabled
{
get { return __outputEnabled; }
set { __outputEnabled = value; }
}

}

　　

示例：

            // 调用示范
            ConsoleOut.Install();

            Console.WriteLine("这行不会输出");
            ConsoleOut.OutputEnabled = true;
            Console.WriteLine("这行可以输出");
            ConsoleOut.OutputEnabled = false;
            Console.WriteLine("这行也不会输出");
