如何在文本中添加 +string？

Question

我想知道如何在 Console.WriteLine / Console.Write 中添加 [+行]。

例如：

string line;
    Console.WriteLine("Enter one or more lines of text (press 'gg' to exit):");
    do
    {
       Console.Write(" ");
        line = Console.ReadLine();
        if (line != "b")
            Console.WriteLine(" Sorry, you wrote **???**, which is wrong. \n Try again." +line);
       else
           Console.WriteLine("u rock");
    }
           while ( line != "gg") ;

我想在句子中间加[+line]，也就是问号所在的位置。我该怎么做？

String interpolation 是您最好的选择（假设您使用的是 C# 6 或更高版本）。记住字符串开头的$：

Console.WriteLine($"Sorry, you wrote {line}, which is wrong. \n Try again.");

你也可以用来分隔加在一起的字符串，尽管这样有点笨拙：

Console.WriteLine("Sorry, you wrote " +  line + ", which is wrong. \n Try again.");
