@sreeni379,

Your code is not right, so you should correct it. Apparently you are trying to save Excel XLSX and PDF files directly to the same (existing) streams which is not possible (you may get “Memory stream is not expandable” error). Moreover, if your workbook has single sheet in it, then the line of code will throw an error as you must have one visible worksheet in the workbook:

workbook.Worksheets[0].IsVisible = false;

I tried the following sample code with a sample Excel file and it works fine:
e.g.
Sample code:

byte[] bytes = File.ReadAllBytes("e:\\test2\\Bk_test1.xlsx");
Stream msFile = new MemoryStream(bytes);

Workbook workbook = new Workbook(msFile);

Aspose.Cells.PdfSaveOptions opts = new Aspose.Cells.PdfSaveOptions();
opts.AllColumnsInOnePagePerSheet = true;
opts.OptimizationType = Aspose.Cells.Rendering.PdfOptimizationType.MinimumSize;

MemoryStream msPdf = new MemoryStream();
workbook.Save(msPdf, opts);
msPdf.Seek(0, SeekOrigin.Begin);

byte[] buffer = new byte[msPdf.Length];
buffer = msPdf.ToArray();

File.WriteAllBytes("e:\\test2\\outputPdfFile1.pdf", buffer);

Hope, this helps a bit.
