Programmatic equivalent of default(Type)

Question

I\'m using reflection to loop through a Type\'s properties and set certain types to their default. Now, I could do a switch on the type and set the defau

Answer 1

I do the same task like this.

//in MessageHeader 
   private void SetValuesDefault()
   {
        MessageHeader header = this;             
        Framework.ObjectPropertyHelper.SetPropertiesToDefault(this);
   }

//in ObjectPropertyHelper
   public static void SetPropertiesToDefault(T obj) 
   {
            Type objectType = typeof(T);

            System.Reflection.PropertyInfo [] props = objectType.GetProperties();

            foreach (System.Reflection.PropertyInfo property in props)
            {
                if (property.CanWrite)
                {
                    string propertyName = property.Name;
                    Type propertyType = property.PropertyType;

                    object value = TypeHelper.DefaultForType(propertyType);
                    property.SetValue(obj, value, null);
                }
            }
    }

//in TypeHelper
    public static object DefaultForType(Type targetType)
    {
        return targetType.IsValueType ? Activator.CreateInstance(targetType) : null;
    }
