Question

I want to get all fields that have null values but i aint even getting any fields:

  [Serializable()]
public class BaseClass
{
    [OnDeserialized()]
    internal void OnDeserializedMethod(StreamingContext context)
    {
        FixNullString(this);
    }

    public void FixNullString(object type)
    {
        try
        {
            var properties = type.GetType().GetFields();


            foreach (var property in from property in properties
                                     let oldValue = property.GetValue(type)
                                     where oldValue == null
                                     select property)
            {
                property.SetValue(type, GetDefaultValue(property));
            }
        }
        catch (Exception)
        {

        }
    }

    public object GetDefaultValue(System.Reflection.FieldInfo value)
    {
        try
        {
            if (value.FieldType == typeof(string))
                return "";

            if (value.FieldType == typeof(bool))
                return false;

            if (value.FieldType == typeof(int))
                return 0;

            if (value.FieldType == typeof(decimal))
                return 0;

            if (value.FieldType == typeof(DateTime))
                return new DateTime();
        }
        catch (Exception)
        {

        }

        return null;
    }
}

And then i have a class :

    [Serializable()]
public class Settings : BaseClass
{
    public bool Value1 { get; set; }
    public bool Value2 { get; set; }
}

But when i comes to

 var properties = type.GetType().GetFields();

then i get 0 fields, it should find 2 fields.

Is type.getType().GetFields() wrong to use ? or am i sending in the wrong class to the base class?

Type.GetFields methods returns all public fields. Fields that the compiler autogenerates for you are private, so you need to specify correct BindingFlags.

type.GetType().GetFields(BindingFlags.Instance | BindingFlags.NonPublic)
