How to convert array of string to enum?

Question

How can I convert an array of string to enum? The following code gives a basic idea about what is expected,

permission.Permissions.Add(Enum.Parse(typeof(PagePermission) ,a );

however, it throws an error like

can not convert object to enum.

Here, PagePermission is enum.

string pagePermission = "View,Edit"; string[] permissions = pagePermission.Split(','); permission.Permissions = new List<PagePermission>(); for (int i = 0; i < permissions.Length; i++) { string a = permissions[i]; permission.Permissions.Add(Enum.Parse(typeof(PagePermission) ,a ); }

When asking a question on StackOverflow, please always copy/paste the exact message of the exception. There's a lot that can be deduced from the precise wording of the error message — Kevin Gosse

Use this

IEnumerable<myEnum> items = myArray.Select(a => (myEnum)Enum.Parse(typeof(myEnum), a));

Enum.Parse returns an object, you need to cast it to the actual enum type. In your case:

permission.Permissions.Add((PagePermission)Enum.Parse(typeof(PagePermission), a);

Otherwise you'd be adding an object to a list of PagePermission, which causes the error you had.

@GoralPatel That's the (PagePermission) bit I added before Enum.Parse(typeof(PagePermission), a). It's used to tell "I know this object is a PagePermission, so consider it as such"
