Why does Console.Out.WriteLine exist?
提问by Kredns
Actually the question should be why does Console.WriteLineexist just to be a wrapper for Console.Out.WriteLine
实际上问题应该是为什么Console.WriteLine存在只是为了包装Console.Out.WriteLine
I found this little method using intellisense, then opened .NET reflectorand 'decompiled' the code for the Console.WriteLinemethod and found this:
我使用智能感知找到了这个小方法，然后打开.NET 反射器并“反编译”了该Console.WriteLine方法的代码，发现了这个：
public static void WriteLine(string value)
{
Out.WriteLine(value);
}
So why is WriteLineimplemented this way? Is it totally just a shortcut or is there another reason?
那么为什么要这样WriteLine实现呢？这完全只是一条捷径还是有其他原因？

Console.WriteLineis a static method. Console.Outis a static object that can get passed as a parameter to any method that takes a TextWriter, and that method could call the non-static member method WriteLine.
Console.WriteLine是一个静态方法。Console.Out是一个静态对象，可以作为参数传递给任何采用 a 的TextWriter方法，并且该方法可以调用非静态成员方法WriteLine。
An example where this would be useful is some sort of customizable logging routines, where you might want to send the output to stdout(Console.Out), stderr(Console.Error) or nowhere (System.IO.TextWriter.Null), or anything else based on some runtime condition.
一个有用的示例是某种可自定义的日志记录例程，您可能希望将输出发送到stdout( Console.Out)、stderr( Console.Error) 或无处 ( System.IO.TextWriter.Null)，或基于某些运行时条件的任何其他内容。

Brad Abrams(The founding member of both CLR and .NET framework at Microsoft) says the following.
Brad Abrams（微软 CLR 和 .NET 框架的创始成员）说如下。
Console.WriteLine() is simply a shortcut for Console.Out.WriteLine. Console was overloaded by WriteLine propery to make that much easier to write.
Console.WriteLine() 只是 Console.Out.WriteLine 的快捷方式。 控制台由 WriteLine 属性重载，以使其更容易编写。
