how to Cast string to a given Enum

Question

how to cast string enum ?

i have the code below , it gives me error when i try to assign string to levelEnum, where levelEnum is an Enumeration..

foreach (CustomProperty prop in requirementTemplate.AttributesCustomList)
{
    if (prop.Name == property)
    {
        return (CRF_DB.CRF_Requirement.LevelEnum) (prop.Value.ToString());
    }
}

Is there a way to put select Enum item by assigning value to it ?

hope it is clear enough

Answer 1

Try the following

return (CRF_DB.CRF_Requirement.LevelEnum)Enum.Parse(
  typeof(CRF_DB.CRF_Requirement.LevelEnum), 
  prop.Value.ToString());

Look at Enum.TryParse

In order to avoid an exception you can check if the value exists within that enumeration by calling IsDefined. The TryParse method would be the optimal solution if you're using .NET 4.0.

foreach (CustomProperty prop in requirementTemplate.AttributesCustomList)
{
    if (prop.Name == property && Enum.IsDefined(typeof(LevelEnum), prop.Value))
    {
        return (LevelEnum)Enum.Parse(typeof(LevelEnum), prop.Value.ToString());
    }
}
