I would hope your view does not contain controller code! you would have a Model which would be bound to the selected value so when posted back to the controller action, the value you want is already bound.

you need to create a property in the model as a SelectedValue and bind to that with the list of items coming from another property (Model.AllRoles)

example:

Model:

public IEnumerable<SelectListItem> AllRoles {get; set;}

public string SelectedRole {get; set;}

View:

@Html.DropDownListFor(m => m.SelectedRole, Model.AllRoles)

When submitted to your controller, the model will have the selected value
