Question

C#在原程序找到的最小整数数据类型

原程序如下： （如果原程序有问题， 请指出） long myLong;
myLong = Convert.ToInt64(Console.ReadLine());
if (myLong < int.MaxValue)
{
Console.WriteLine(myLong + " is less than " + int.MaxValue + " so it will not overflow an int.");
}
else
{
Console.WriteLine(myLong + " is more than " + int.MaxValue + " so it will overflow an int.");
} 要求加强该程序找到的最小整数数据类型(byte, short, int 和 long)，值不会溢出

Answer 1

既然是long型，比较的时候当然也要是long.MaxValue long myLong;
myLong = Convert.ToInt64(Console.ReadLine());
if (myLong < long.MaxValue)
{
Console.WriteLine(myLong + " is less than " + long.MaxValue + " so it will not overflow an long.");
}
else
{
Console.WriteLine(myLong + " is more than " + long.MaxValue + " so it will overflow an long.");
}
Console.Read();这样就可以了
