Question

When creating a new item; is there any way to access all the field values that are set.

Since I’m using Entity.GetModifiedMembers() method to access the values of the fields that are changed when updating for logging purposes, the purpose is to have the equivalent result through an entity when creating, like a method Entity.GetSetMembers().

So in general, all I need is a key-value pair with “member name” and “value” items.

Example:

public class SomethingEntity
{
    public int Id {get;set;}
    public string Name {get;set;}
    public DateTime Created {get;set;}
    public DateTime Modified {get;set;}
}

public Dictionary<string, string> GetFieldsAndValuesOfCreatedItem(object entity)
{
    //This is what I need, that can take all the objects from an entity and give
    //the property-value pairs for the object instance
    return RequieredMethod(entity);
}

public ExampleMethod()
{
    var newObject = new SomethingEntity() { Name = "SomeName", Created = DateTime.Now };
    Entity.insetOnSubmit(newObject);
    Entity.SubmitChanges();

    var resultList = GetFieldsAndValuesOfCreatedItem(newObject);

    foreach (var propertyKeyValue in resultList)
    {
        var propertyString = "Property Name: " + propertyKeyValue.Key;
        var valueString = "Value : " + propertyKeyValue.Value; 
    }
}

I’ve found out that, Reflection is the answer for that as far as I could find: so here is the method I’ve come up with:

public static Dictionary<string, string> GetFieldsAndValuesOfCreatedItem(object item)
{
    var propertyInfoList = item.GetType().GetProperties(BindingFlags.DeclaredOnly |
                                                            BindingFlags.Public |
                                                            BindingFlags.Instance);

    var list = new Dictionary<string, string>();

    foreach (var propertyInfo in propertyInfoList)
    {
        var valueObject = propertyInfo.GetValue(item, null);
        var value = valueObject != null ? valueObject.ToString() : string.Empty;

        if (!string.IsNullOrEmpty(value))
        {
            list.Add(propertyInfo.Name, value);
        }
    }

    return list;
}
