Examples

DicomDataset data = file.Dataset;
DateOnly? studyDate = data["StudyDate"]?.GetDate();
DicomPersonName? patient = data["PatientName"]?.GetPersonName();
double[] window = data["WindowCenter"]?.GetNumbers() ?? [];

// A sequence is a list of datasets; text decodes by the dataset's Specific Character Set.
foreach (DicomDataset item in data["ContentSequence"]?.Items ?? [])
{
    Console.WriteLine(item.GetString("ReferencedSOPClassUID"));
}

// Every element prints as a dump line, such as "(0028,0010) US Rows: 4".
foreach (DicomElement element in data)
{
    Console.WriteLine(element);
