I dont know why getting error 'CLRObject'

System.IO.FileStream fs,inputStream,outputStream;
System.IO.Directory ff;
System.IO.Compression.GZipStream GZipStream, compStream ;
str s;
System.Byte[] buffer;
int bytesRead;
System.IO.StreamWriter sw;
;

inputStream = new System.IO.FileStream("c:\\temp\\test", System.IO.FileMode::Open, System.IO.FileAccess::Read);
outputStream = new System.IO.FileStream("c:\\temp\\test.zip", System.IO.FileMode::OpenOrCreate, System.IO.FileAccess::Write);

GZipStream = new System.IO.Compression.GZipStream(outputStream, System.IO.Compression.CompressionMode::Compress);

buffer = inputStream.get_Length();
bytesRead = inputStream.Read(buffer, 0, buffer.get_Length());
compStream.Write(buffer, 0, buffer.get_Length());

inputStream.Close();
compStream.Close();
outputStream.Close();

You are initialising the variable GZipStream:

GZipStream = new System.IO.Compression.GZipStream(outputStream, System.IO.Compression.CompressionMode::Compress);

But then writing using the variable compStream:

compStream.Write(buffer, 0, buffer.get_Length());

What exactly does the error message say?

It's a runtime error, right?

Are you running the code on client or server?

yes but I getting the actual error on the previous line

So,

inputStream = new System.IO.FileStream("c:\\temp\\test", System.IO.FileMode::Open, System.IO.FileAccess::Read);

error is object clrobject could not be created

Are you sure the file exists? Consider if the code is running on the client or aos - 'C:\\temp\\' will likely be a different location depending on the tier.

Please also have a look at this: msdn.microsoft.com/.../fileiopermission.aspx

You may need to use the .net equivalent of the class described in the link.

Checking if the file exists on the AOS is the right first step.

The next one is checking if the AOS service has permissions to open it.

file exists and permissions is open for AOS services. I guess I'll have to find a different solution, thank you.

Make sure you test these claims properly; it's easy to overlook something. For example, you may want to utilize WinAPIServer::fileExists() to test the first one.

If both things correct, the only other reason I can think of is that the file is exclusively locked by some other application. Maybe you still have it open in an editor, for instance.
