c# - For 循环和 If 语句

Question

int i;
int[] mArray = new int[5];

for (i = 0; i < mArray.Length; i++)
{
    Console.WriteLine("Please enter a number:");
    mArray[i] = Convert.ToInt32(Console.ReadLine());

    if (mArray[i] >= 50 && mArray[i] <= 10)
    {
        Console.WriteLine("Please enter numbers only between 10 and 50.");
        mArray[i] = Convert.ToInt32(Console.ReadLine());
    }

}

当 if 语句中有两个规则时，它似乎无法工作 if (mArray[i] >= 50 && mArray[i] <= 10)

但它适用于 1 条规则 if (mArray[i] >= 50)

Answer 1

你应该使用 || 而不是 &&

mArray[i] >= 50 || mArray[i] <= 10
