I a razor view .I have line like bleow
<option value='@{(Int16)PhoneType.Work}'>@PhoneType.Work</option>
This is an option in a select list/dropdownlist In this I have an enum PhoneType. For text filed @PhoneType.Work works fine but for value field @{(Int16)PhoneType.Work is not working
这是选择列表/下拉列表中的一个选项 在此我有一个枚举 PhoneType。对于文本归档 @PhoneType.Work 工作正常，但对于值字段 @{(Int16)PhoneType.Work 不起作用
What can i do to get integer value of the enum at value field
我该怎么做才能在 value 字段中获取枚举的整数值
回答by Stéphane Bebrone
This syntax should do the trick (note the () instead of {}):
这种语法应该可以解决问题（注意 () 而不是 {}）：
<option value='@( (Int16) PhoneType.Work )'>@PhoneType.Work</option>
回答by dove
Why not have another field on your viewModel that is an integer
为什么不在您的 viewModel 上有另一个整数字段
public WorkId {get {return (int)Work; }
and use this in your view
并在您看来使用它
<option value='@PhoneType.WorkId'>@PhoneType.Work</option>

We can use ChangeType function as below. Hope this helps for someone in future.
我们可以使用 ChangeType 函数，如下所示。希望这对将来的某人有所帮助。
<option [email protected](PhoneType.Work, PhoneType.Work.GetTypeCode())>@PhoneType.Work</option>
or
或者
<option [email protected](PhoneType.Work, typeof(int))>@PhoneType.Work</option>
