c#如何使用READLINE读取输入并用INT32中PARSE换为整数,最后转化为字符输出

写个例子，谢

Answer 1

Console.WriteLine("请输入数字:");
string input = Console.ReadLine();
try
{
int i = int.Parse(input);
Console.WriteLine("输入的数字为：" + i.ToString());
}
catch
{
Console.WriteLine("输入字符为非数字");
}
Console.ReadKey();
在一楼的基础上加上try...catch，锦上添花

Console.WriteLine("请输入数字！");
string s = Console.ReadLine();
int i = int.Parse(s);
