Question

类赋值是在这种情况下创建自己的自定义异常（MyEmptyStringException）。

这就是我所拥有的：

class Program
    {
        public class MyEmptyStringException : Exception
        {
          public MyEmptyStringException(string message) : base(message) { }
        }

        public class MyOutOfRangeException : Exception
        {
            public MyOutOfRangeException(string message) : base(message) { }
        }

        static void Main(string[] args)
        {
            string testStr;
            byte testByte;
            bool validValue = false;

            Student myStudent = new Student();

            do
            {//start do loop

                Console.WriteLine("Enter student's first name");

                try
                {
                    testStr = (Console.ReadLine());

                    if ((string.IsNullOrEmpty(testStr)))
                    {
                        throw new MyEmptyStringException("Answer was blank");
                        // Console.WriteLine("String is empty");
                    }
                    else
                    {
                        validValue = true;
                    } //end if
                }
                catch (FormatException e)
                {
                    Console.WriteLine("\n" + e.Message + "Format Exception!\n");
                }
                catch (OverflowException e)
                {
                    Console.WriteLine("\n" + e.Message + "Overflow Exception\n");
                }

             } while (!validValue);
            myStudent.firstName = Console.ReadLine();

对我而言，这里有错误：

throw new MyEmptyStringException("Answer was blank");

错误消息：MyEmptyStringException未处理。任何帮助将不胜感激。

抓住您的自定义例外：

MyEmptyStringException和MyOutOfRangeException

例如：

try
 {

 }
 catch (MyEmptyStringException mese)
 {
    Console.WriteLine(mese.Message);
 }
 catch (MyOutOfRangeException moofre)
 {
    Console.WriteLine(moofre.Message);
 }

c＃自定义异常未处理
