That's correct. You can use the following logic to copy values from oldJob to newJob

foreach(....)

{

var valueToCopy = dataProperty.GetValue(oldJob);

dataProperty.SetValue(newJob, valueToCopy);

}

so this is what i have so far then

           var query = _manager.JobHistories                .Where(j => j.RefNo == refNo);           var oldJob = query.Execute().FirstOrDefault();            var newJob = _manager.CreateEntity<JobHistory>();            var entityMetadata = _manager.MetadataStore.GetEntityMetadata(typeof(JobHistory));             foreach (var dataProperty in entityMetadata.DataProperties)            {                            }

so now i need to copy the property values from oldJob to newJob

Hi Bill,

One way to do this is through the use of the entity metadata.

Below is a code snippet:

//Grab an entity metadata using its type

var entityMetadata = entityManager.MetadataStore.GetEntityMetadata(typeof(YourEntity));

//Loop through the data properties of the entity

foreach (var dataProperty in entityMetadata.DataProperties) {

//Cloning logic here

dataProperty.SetValue(...);

}

Hope this helps.

I have a situation where i have an called job which is an instance of the class JobHistory. I need to pass a job object to a method called BuildNewJobFromExistingJob(). In the method, I need to create a new job object. Then i need to copy all the data from the old object to the new object. Finally i need to change a few of the fields in the object.

I am thinking of the following as a solution.

var job = Repository.CreateJobHistory()

then i want to loop through all the fields of the old object to the new object. I don't want to hard code the copying of the data as fields may be added in the future.

How do i loop through all the fields in and object copying the data from one to a new object of the same type?
