如何将WriteLine分割为多行

一次调用不应该产生这种结果，因为您有两个字符串字面值。事实上，这甚至不能编译…

试题:

Console.WriteLine("x'nx");

或者更糟:

Console.WriteLine(@"x
x");

您可以简单地使用@引号字符串字面值，如:

Console.WriteLine(@"X
X
X
X
X
X");

如果您有一个项目集合，并且希望将它们全部写在单独的行上，那么这总是一个选项:

var myItems = new[] { "x", "x", "x", "x", "x" };
Console.WriteLine(String.Join(Environment.NewLine, myItems));
// or without the collection
Console.WriteLine(String.Join(Environment.NewLine, "x", "x", "x", "x", "x"));

Try This:

Console.WriteLine(@"x
x
x
something
    notice this respects identation");

不太容易，因为WriteLine只接受一个输入parm，或者一个带有格式化选项的parm，所以要么

Console.WriteLine("x'nx"); 
or
Console.WriteLine("{0}'n{1}'n{2}","x","x","x");  

'n是'换行'转义字符

(第二个示例格式为3 x)

你可以考虑多个writeline，每个'x'一个?

另一个选项是这样的。(虽然我认为正确的答案是使用'n)

static void Main(string[] args)
{
    WriteMulti("A", "B", "C", "D", "E", "F", "G");
    Console.ReadLine();
}
static void WriteMulti(params string[] args)
{
    foreach (string arg in args)
        Console.WriteLine(arg);
}

以防万一您正在寻找某种方法将多个参数写入每个参数的不同行。下面是几个选项:

/// <example>
    /// Console.WriteLine(new LinesItem("X", "X"));
    /// </example>
    public class LinesItem
    {
        private readonly string _lineSeparator;
        private readonly object[] _items;
        public LinesItem(params object[] items) : this("'r'n", items)
        {
            _items = items;
        }
        public LinesItem(string lineSeparator, params object[] items)
        {
            _lineSeparator = lineSeparator;
            _items = items;
        }
        public override string ToString()
        {
            return String.Join(_lineSeparator, _items.Select(x => x.ToString()).ToArray());
        }
    }
    //OR
    /// <summary>
    /// Because System.Console is a static class you cannot use Extension methods which would
    /// have been nice.  Instead you can simply make another static class to do extra things.
    /// </summary>
    /// <example>
    /// ExtendedConsole.WriteLines("X", "X");
    /// </example>
    public static class ExtendedConsole
    {
        public static void WriteLines(params object[] items)
        {
            foreach(var item in items)
            {
                Console.WriteLine(item);
            }
        }
    }

不调用WriteLine，只需调用Write:

Console.Write("x");
Console.Write(Environment.NewLine);
Console.Write("x");
