c#枚舉數(shù)字轉(zhuǎn)枚舉
1) What is the correct output of given code snippets in C#.NET? using System;class program {enum emp_salary : int{emp1 = 10000,emp2 = 15000,emp4 = 20000}static void Main(string[] args){int sal = (int)emp_salary.emp2;Console.WriteLine(sal);} }10000
15000
Syntax error
Runtime exception
Correct answer: 2
15000
The above code will print "15000" on console screen.
1)C＃.NET中給定代碼段的正確輸出是什么？10000
15000
語法錯(cuò)誤
運(yùn)行時(shí)異常
正確答案：2
15000
上面的代碼將在控制臺(tái)屏幕上打印“ 15000” 。
2) What is the correct output of given code snippets in C#.NET? using System;class program {enum emp_salary : byte{emp1 = 10000,emp2 = 15000,emp4 = 20000}static void Main(string[] args){int sal = (int)emp_salary.emp2;Console.WriteLine(sal);} }10000
15000
Syntax error
Runtime exception
Correct answer: 3
Syntax error
The above code will generate syntax error because the value of enums is outside the range of byte.
2)C＃.NET中給定代碼段的正確輸出是什么？10000
15000
語法錯(cuò)誤
運(yùn)行時(shí)異常
正確答案：3
語法錯(cuò)誤
上面的代碼將產(chǎn)生語法錯(cuò)誤，因?yàn)閑nums的值超出了字節(jié)范圍。
3) What is the correct output of given code snippets in C#.NET? using System;class program {enum emp_salary : float{emp1 = 10000,emp2 = 15000,emp4 = 20000}static void Main(string[] args){int sal = (int)emp_salary.emp2;Console.WriteLine(sal);} }10000
15000
Syntax error
Runtime exception
Correct answer: 3
Syntax error
The above code will generate syntax error because we cannot use a float with enum like this.
3)C＃.NET中給定代碼段的正確輸出是什么？10000
15000
語法錯(cuò)誤
運(yùn)行時(shí)異常
正確答案：3
語法錯(cuò)誤
上面的代碼將產(chǎn)生語法錯(cuò)誤，因?yàn)槲覀儾荒芟襁@樣使用帶枚舉的浮點(diǎn)數(shù) 。
4) What is the correct output of given code snippets in C#.NET? using System;class program {enum emp_salary : int{emp1 = 10000,emp2 = 15000,emp4 = 20000}static void Main(string[] args){emp_salary sal = emp_salary.emp2;if (sal == emp_salary.emp2){Console.WriteLine("15000");}} }10000
15000
Syntax error
Runtime exception
Correct answer: 3
15000
The above code will print "15000" on the console screen.

5) What is the correct output of given code snippets in C#.NET? using System;class program {int A = 10000;int B = 15000;int C = 20000;enum emp_salary : int{emp1 = A,emp2 = B,emp4 = C}static void Main(string[] args){emp_salary sal = emp_salary.emp2;if (sal == emp_salary.emp2){Console.WriteLine("15000");}} }10000
15000
Syntax error
Runtime exception
Correct answer: 3
Syntax error
The above code will generate a syntax error.
