c#: how to read parts of a file? (DICOM)

Question

I would like to read a DICOM file in C#. I don\'t want to do anything fancy, I just for now would like to know how to read in the elements, but first I would actually like

Answer 1

Just some pseudologic

How to I read the header file and verify if it is a DICOM file by checking for the 'D','I','C','M' characters after the 128 byte preamble?

• Open as binary file, using File.OpenRead
• Seek to position 128 and read 4 bytes into the array and compare it againts byte[] value for DICM. You can use ASCIIEncoding.GetBytes() for that

How do I continue to parse the file reading the other parts of the data?

• Continue reading the file using Read or ReadByte using the FileStream object handle that you have earlier
• Use the same method like above to do your comparison.

Dont forget to close and dispose the file.
