我试图让一个程序让用户输入3个名字，然后按字母顺序显示它们但我不知道如何以这种方式显示字符串任何帮助将不胜感激

 string firstName, secoundName, thirdName;
        int myMoves = 1;
        int myHolder;

        Console.WriteLine("Please Enter The First Name: ");
        firstName = Console.ReadLine();

        Console.WriteLine("Please Enter The Secound Name: ");
        secoundName = Console.ReadLine();

        Console.WriteLine("Please Enter The Third Name: ");
        thirdName = Console.ReadLine();

        do
        {
            if()
            {

            }

        } while (myMoves > 0);

不是为每个名称分别使用单独的变量，而是将名称添加到可以进行本机排序的集合类型，例如List<string>：

string[] prompts = new [] { "First", "Second", "Third" };
string tempName = null;

// Create an empty collection of strings for the names,
// starting off with a capacity equal to the number of prompts
IList<string> names = new List<string>(prompts.Length);

// Let's make the collection smarter so you don't need to repeat code
foreach (string prompt in prompts)
{
    Console.WriteLine("Please Enter The {0} Name: ", prompt);

    // collect the name
    tempName = Console.ReadLine();

    // check that something was entered before adding it to the list
    if (!string.IsNullOrEmpty(tempName))
    {
        names.Add(tempName);
    }

    // reset the temporary name variable; probably not necessary but...
    tempName = null;
}

// Sort the list
names.Sort(); // will do a default string comparison for ordering

// Print the names
foreach (string name in names)
{
    Console.WriteLine(name);
}

按字母顺序显示名称
