Question

在C#中，输入一个单词，怎么知道它有多少位字母

Answer 1

class Program//该程序不完整，你只需少加修改
{

static int num=0;
static void Main(string[] args)

{

Console.WriteLine("请输入一串字符：");

string str = Console.ReadLine();

new Program().GetWordsCount(str);

Console.WriteLine(num+1);
Console.ReadKey();

}

private void GetWordsCount(string str)
{

//空格标点符号，数字

for (int i = 0; i < str.Length; i++)

{

string obj = str[i].ToString();

if (IsNumber(obj) || obj == " " || IsPunctuation(obj))

{

num++;

GetWordsCount(str.Substring(i+1));

}
}
}

//判断是否是数字

private bool IsNumber(string num)

{
bool resu=true ;
try
{

int n = Convert.ToInt32(num);
}

catch (Exception)

{

resu = false;
}

return resu;
}

//判断是否是标点符号

private bool IsPunctuation(string s)

{
bool resu = false;

string charlist = "，。？！";

if (charlist.Contains(s))

{

resu = true;

}

return resu;
}
}
