问题是我不确定如何正确设置代码格式,以便当用户输入状态缩写时,main方法在GetValidState方法中查找它,以使用户知道他们输入的内容是否有效。关键之一是缩写必须长2个字母。
static void Main(string[] args)
{
string stateAbbreviation;
bool fieldValidationSuccess = false;
promt = GetValidState("State (2 letters):\t");
stateAbbreviation = ReadLine();
}
public static string GetValidState(string prompt, string[] sortedStateArray)
{
string[] states = new string[] { "AK", "WA", "OR", "CA", "AZ", "NM", "CO", "UT" };
fieldValidationSuccess = false;
while (!fieldValidationSuccess)
{
int sub = 0;
while (sub < states.Length && !fieldValidationSuccess)
{
if (states[sub].ToUpper() == stateAbbreviation.ToUpper())
{
fieldValidationSuccess = true;
}
else
{
sub++;
}
}
if (!fieldValidationSuccess)
{
WriteLine("\n***ERROR. We do not ship to {0}.", stateAbbreviation);
}
}
}
•建立一个验证循环,以确保用户输入有效的状态缩写。
•使用循环在数组中搜索有效状态。不要使用Array.BinarySearch
•调用GetValidString从用户获取字符串。最小和最大参数都使用2。

我不确定这是否是您想要的。您想要一个代码来检查STATE是否在您的数组中?
public static void GetValidState(string prompt, string state)
{
string[] states = new string[] { "AK", "WA", "OR", "CA", "AZ", "NM", "CO", "UT" };
if (!states.Contains(state))
WriteLine("\n***ERROR. We do not ship to {0}.", state);
}
