I am pleased to announced that GDCM is now supporting yet another
target language: C#.
You can now write code in C# and use the GDCM library (C++), thanks to
the use of SWIG for providing the wrapping layer.

Grassroots DiCoM is a C++ library for DICOM medical files. It is
automatically wrapped to python/C#/Java (using swig). It supports
RAW,JPEG (lossy/lossless),J2K,JPEG-LS,RLE and deflated. It also comes
with DICOM Part 3,6 & 7 of the standard as XML files.
