(4个答案)


3年前关闭。

string num = Console.ReadLine();

string a="";
string b="";
for (int i = num.Length; i > 0; i--)
{
    if (num[i] =='-')
    {
        break;
    }
    else
    {
        b +=num[i].ToString();
    }
}

//then reverse b 
//a=num-(b.lenght+1);
Console.WriteLine(b);``

An unhandled exception of type 'System.IndexOutOfRangeException' occurred in number_spliter.exe

Additional information:

Index was outside the bounds of the array.

最佳答案

数组从索引零开始

for (int i = num.Length-1; i >= 0; i--)
