Convert.ChangeType How to convert from String to Enum

public static T Convert<T>(String value)
  {
    return
(T)Convert.ChangeType(value, typeof(T));
  }
   public enum
Category 
   {
       Empty,
       Name,
       City,
       Country
   }
  Category
cat=Convert<Category>("1");//Name=1

When I call Convert.ChangeType, the system throws an exception on the impossibility of conversion from String to Category. How to do the conversion? Maybe I need to implement any converter for my type?

Hi Ben,

Use Enum.Parse method for this.

public static T Convert<T>(String value)
{
    if(typeof(T).IsEnum)
       return(T)Enum.Parse(typeof(T), value);
    return(T)Convert.ChangeType(value, typeof(T));
}
