Question

如何通过从键盘读取名称和姓氏并仅使姓氏字母变大来打印？

string name;
Console.Write("Name and surname:");
name=Console.ReadLine();

int word= name.LastIndexOf(" ");
Console.WriteLine(name.Substring(word).ToUpper());

我可以写姓，但不能添加名字。对不起，我的英语。.

Answer 1

我会使用.Split()来分隔姓氏和名字

Console.Write("Name and surname:");
string name = Console.ReadLine();
Console.WriteLine(name.Split().First().ToUpper());
Console.WriteLine(name.Split().Last().ToUpper());

如果您想呆在Substring()上，这就是方法

Console.Write("Name and surname:");
string name = Console.ReadLine();
int word = name.LastIndexOf(" ");
Console.WriteLine(name.Substring(word+1).ToUpper());
Console.WriteLine(name.Substring(0, word).ToUpper());

我解决了我的问题。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Globalization;/*Add this library for ToTitleCase*/

namespace String_denemeler
{
    class Program
    {
        public static string ToTitleCase(string Text)/*And Add this for ToTitleCase*/
        {
            return CultureInfo.CurrentCulture.TextInfo.ToTitleCase(Text);
        }
        static void Main(string[] args)
        {
            string name;
            Console.Write("Name&Surname:");
            name = Console.ReadLine();
            name= ToTitleCase(name);

            int index = name.LastIndexOf(" ");
            Console.WriteLine(name.Substring(0, index) + name.Substring(index).ToUpper());

        }
    }
}
