我是 C# 的新手,被告知要创建一个基于文本的口袋妖怪战斗模拟器,所以在下面的代码中,我有一个方法来获取用户输入并决定口袋妖怪获得哪种性质:
public static void NatureSelection(out int statIndex1, out int statIndex2)
{
Console.WriteLine("If you wish to have a neutral nature, Enter 0 in the next line, If not, enter any key to continue");
char holder = Convert.ToChar(Console.ReadKey());
statIndex1 = Convert.ToInt16(holder);
if (statIndex1 == 0)
{
statIndex2 = 0;
}
Console.WriteLine("Please Select A Nature For Your Pokemon By Entering The Number Beside The Stats That You Want To Increase ");
statIndex1 = Convert.ToInt16(Console.ReadKey());
while (!(statIndex1 > 0 && statIndex1 <=5))
{
statIndex1 = Convert.ToInt32(Console.ReadKey());
Console.WriteLine("Invalid Value,Please Try Again");
}
Console.WriteLine("Now Enter The Number Beside The Stats That You Want To Decrease ");
statIndex2 = Convert.ToInt32(Console.ReadKey());
while (!(statIndex2 > 0 && statIndex2 <= 5))
{
statIndex2 = Convert.ToInt16(Console.ReadKey());
Console.WriteLine("Invalid Value,Please Try Again");
}
}
但是,当我尝试将 readkey 转换为 int 时,它会给出一个错误消息:
这一行给出了错误:
char holder = Convert.ToChar(Console.ReadKey());
mscorlib.dll 中出现“System.InvalidCastException”类型的未处理异常
附加信息:无法将“System.ConsoleKeyInfo”类型的对象转换为“System.IConvertible”类型。
有人可以解释这是什么意思以及我该如何解决?
