我有一门课叫问题（复数）。在这个类中有一个名为Question（单数）的枚举，看起来像这样。
public enum Question
{
Role = 2,
ProjectFunding = 3,
TotalEmployee = 4,
NumberOfServers = 5,
TopBusinessConcern = 6
}
在Questions类中，我有一个get（intfoo）函数，它为该foo返回Questions对象。有没有一种简单的方法可以从枚举中获取整数值，这样我就可以执行类似于Questions.get（Questions.Role）的操作？
当前回答
这比你想象的要简单-枚举已经是int。只需要提醒一下：
int y = (int)Question.Role;
Console.WriteLine(y); // Prints 2
其他回答
我想建议“从枚举中获取‘int’值”的示例是
public enum Sample
{
Book = 1,
Pen = 2,
Pencil = 3
}
int answer = (int)Sample.Book;
现在答案是1。
为了确保枚举值存在，然后解析它，还可以执行以下操作。
// Fake Day of Week
string strDOWFake = "SuperDay";
// Real Day of Week
string strDOWReal = "Friday";
// Will hold which ever is the real DOW.
DayOfWeek enmDOW;
// See if fake DOW is defined in the DayOfWeek enumeration.
if (Enum.IsDefined(typeof(DayOfWeek), strDOWFake))
{
// This will never be reached since "SuperDay"
// doesn't exist in the DayOfWeek enumeration.
enmDOW = (DayOfWeek)Enum.Parse(typeof(DayOfWeek), strDOWFake);
}
// See if real DOW is defined in the DayOfWeek enumeration.
else if (Enum.IsDefined(typeof(DayOfWeek), strDOWReal))
{
// This will parse the string into it's corresponding DOW enum object.
enmDOW = (DayOfWeek)Enum.Parse(typeof(DayOfWeek), strDOWReal);
}
// Can now use the DOW enum object.
Console.Write("Today is " + enmDOW.ToString() + ".");
在Visual Basic中，它应该是：
Public Enum Question
Role = 2
ProjectFunding = 3
TotalEmployee = 4
NumberOfServers = 5
TopBusinessConcern = 6
End Enum
Private value As Integer = CInt(Question.Role)
尝试使用此方法，而不是将enum转换为int：
public static class ReturnType
{
public static readonly int Success = 1;
public static readonly int Duplicate = 2;
public static readonly int Error = -1;
}
public enum ViewType
{
List = 1,
Table = 2,
};
// You can use the Enum type as a parameter, so any enumeration from any enumerator
// cshtml
// using proyects.Helpers
// @if (Model.ViewType== (int)<variable>.List )
