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() + ".");

您可以通过对定义的枚举类型实现一个扩展方法来做到这一点：

public static class MyExtensions
{
    public static int getNumberValue(this Question questionThis)
    {
        return (int)questionThis;
    }
}

这简化了获取当前枚举值的int值：

Question question = Question.Role;
int value = question.getNumberValue();

or

int value = Question.Role.getNumberValue();

将为您提供一个列表，其中包含枚举的所有整数值：

List enumValues=Enum.GetValues（typeof（EnumClass））.Cast（）.ToList（）；

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 )

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 QuestionType
{
    Role = 2,
    ProjectFunding = 3,
    TotalEmployee = 4,
    NumberOfServers = 5,
    TopBusinessConcern = 6
}

…是一个很好的声明。

您必须将结果强制转换为int，如下所示：

int Question = (int)QuestionType.Role

否则，类型仍然是QuestionType。

这种严格程度是C#的方式。

一种替代方法是改用类声明：

public class QuestionType
{
    public static int Role = 2,
    public static int ProjectFunding = 3,
    public static int TotalEmployee = 4,
    public static int NumberOfServers = 5,
    public static int TopBusinessConcern = 6
}

声明不那么优雅，但不需要将其转换为代码：

int Question = QuestionType.Role

或者，您可能会对Visual Basic感到更舒服，它在许多方面都满足了这种期望。
