If you are using our .NET classes version 16, you can access the internal data buffer of the RasterImage pixels using the RasterImage.Data property. You can then copy that data using System.Runtime.InteropServices.Marshal.Copy

You can read in our .NET help file about RasterImage.Data Property, and also it has a sample code about how to do it. If you try that code and face problems, please explain the type of problem you faced in detail.

Hello
RasterImage.Data is only Pixcel data of this Image?
But Now I want to take all data of RasterImage except header of it(The header consists of a 128 byte File Preamble, followed by a 4 byte DICOM prefix.)
It means that I want to get all data of Image after from the byte after prefix "DICM"
Can you help me!
Thanks in advance!

Once an image is loaded in a RasterImage object, it is no longer a DICOM data set in memory. It is only an image.

If you want to get the Data Elements stored in the DICOM data set, you should use DicomDataSet.Load method not the RasterCodecs.Load method or the RasterImage object.
