Load document from Stream

There might be the case when your document is not physically located on the disk. Instead, you have the document in the form of a stream. In this case, to avoid the overhead of saving stream as a file on disk, GroupDocs.Viewer enables you to render the file streams directly.

The following are the steps to be followed:

• Specify the method to obtain document stream; 
• Pass method’s name to Viewer class constructor.

Following code snippet serves this purpose.

public static void LoadDocumentFromStream()
{
   using (Viewer viewer = new Viewer(GetFileStream))
    {
        HtmlViewOptions viewOptions = HtmlViewOptions.ForEmbeddedResources();
        viewer.View(viewOptions);
    }
}

private static Stream GetFileStream() => return File.OpenRead("sample.docx");
