Anybody else have any ideas on this?
Thanks,

Hey Scott:
Wouldn't that make my code look too simple? ;-)
Just kidding...
The ConvertToBytes method uses a StreamWriter and a MemoryStream to
convert the array. I pulled this out and used your simpler method and
it doesn't change the outcome of the code.
I have been putting in some long hours on this project and working
when I am probably too tired to do so. Sometimes things just don't
come to you and when you find a method that works, you don't question
it much...
Thanks for your help.

DB,
Why the 'round-about way of creating a byte array? Won't this work?
byte[] buffer = newbyte[bufferSize];
What's going on inside your HdfHelper.ConvertToBytes function?

Hey all:
Trying to take a dataset of float values and build an array that can
be used to generate a raster. If i have code something like this:
*// Open up the dataset.
H5DataSetId curDepthDataset = H5D.open(curHDF, curName1 + "/" +
curName2 + "/" + curName3 + "/depth");
H5ObjectWithAttributes curDepthAttObj =
(H5ObjectWithAttributes)curDepthDataset;
// Create a Byte[] to hold the depth data.
H5DataTypeId datasetType = H5D.getType(curDepthDataset);
H5T.H5TClass datasetClass = H5T.getClass(datasetType);
H5DataTypeId datasetNativeType = H5T.getNativeType(datasetType,
H5T.Direction.ASCEND);
int bufferSize = H5T.getSize(datasetNativeType);
System.Array buffer =
System.Array.CreateInstance(Type.GetType("System.Byte"), bufferSize);
Byte[] bArray = HdfHelper.ConvertToBytes(buffer);
H5D.read(curDepthDataset, datasetNativeType, new H5Array<byte>(bArray));*
Why would this give me an error like this:
*FatalExecutionEngineError was detected*
*The runtime has encountered a fatal error. The address of the error
was at 0x6b344243, on thread 0x334. The error code is 0xc0000005.
This error may be a bug in the CLR or in the unsafe or non-verifiable
portions of user code. Common sources of this bug include user
marshaling errors for COM-interop or PInvoke, which may corrupt the
stack.**
*I am having no trouble using this method to read the attributes out
of the individual groups.
Thanks,
DB
