在上面的代码中，这"{0，-25}" 是什么意思?

In above code what does this "{0,-25}" thing mean?

推荐答案

您提到很难看到它的作用:那是因为它添加了空格，而这些空格很难在控制台中看到.尝试在输出之前和之后直接添加一个字符，这样您可以更清楚地看到空格，如以下示例所示:

You mention it's hard to see what it does: that's because it adds spaces and those are difficult to see in the console. Try adding a character directly before and after the output so you can more clearly see the space, like the examples below:

此

Console.WriteLine("[{0, -25}]", "Microsoft"); // Left aligned 
Console.WriteLine("[{0,  25}]", "Microsoft"); // Right aligned
Console.WriteLine("[{0,   5}]", "Microsoft"); // Ignored, Microsoft is longer than 5 chars

将导致此结果(带有空格)

Will result in this (with spaces)

[Microsoft                ]
[                Microsoft]
[Microsoft]

在控制台窗口中如下所示:
