Copying DicomItems from one file to another without checking the type of each

[James Allsopp]

Hi,

 I'm looping through the attributes in one file and trying to write them to another file. I could solve the problem for some attribute types with a line like;

            foreach (DicomItem attribute in file1.Dataset)

            {

                try

                {

                    file.Dataset.Add(attribute.Tag,attribute.ToString());

                }

                catch (Exception e)

                {

                    Debug.WriteLine(e);

                }

            }

However a lot of lines throw exceptions. Is there a reliable technique for handling this so I can just copy the attribute from one file into another without having to test each value, find its type and cast appropriately. I'm not sure how to handle the generic T that the Add method has,

Thanks,

James

Hi James,

are you copying a few items or (practically) the entire file? If you are copying (most) of the file, you could use the Clone extension method:

var newFile = oldFile.Clone();

You might also want to look into the code of the Clone extension method here: https://github.com/fo-dicom/fo-dicom/blob/development/DICOM/DicomFileExtensions.cs

to get some inspiration of how you can proceed if the Clone method is not sufficient for you.
