how to set a file name and extension when insert ole object using MemoryStream?
example1:
var document = new Document();
var builder = new DocumentBuilder(document);
var shape = builder.InsertOleObject(“D:\1.zip”, false, true, null);
document.Save(“D:\testInsertZip.docx”);

example2:
var document = new Document();
var builder = new DocumentBuilder(document);

        var bs = File.ReadAllBytes("D:\\1.zip");
        using (var stream=new MemoryStream(bs))
        {
            var shape = builder.InsertOleObject(stream, "Package", true, null);
        }
        
        document.Save("D:\\testInsertZip2.docx");

in the example2, when clicking on icon, it asks for the application to open that embedded file.
I dont wan’t to save data to file, because there are many data need to handle, is there any other method to set the file name and extension of inserted stream, so the microsoft word can recognize the file format?
i saw the return shape.OleFormat has two properties: SuggestedExtension and SuggestedFileName may can do this, but they are readonly.

Thanks for your inquiry. We are looking into your requirement and will update you soon.

Furthermore, please note SuggestedExtension and SuggestedFileName is read only properties used to get embedded Ole Objects information.

Document doc = new Document("Sample.docx");
int i = 0;
// Get collection of shapes
NodeCollection shapes = doc.GetChildNodes(NodeType.Shape, true);
Console.Out.WriteLine("No. of Shapes:"+shapes.Count);
// Loop through all shapes
foreach (Aspose.Words.Drawing.Shape shape in shapes)
{
    if (shape.OleFormat != null)
    {
        Console.Out.WriteLine(shape.OleFormat.SuggestedExtension);
        shape.OleFormat.Save(String.Format("E:\\Data\\out_{0}.{1}", i++, shape.OleFormat.SuggestedExtension));
    }
   
}

We would like to share with you that support of setting file name and extension was added in Aspose.Words 17.11. The public property OlePackage was added to the OleFormat class to set file name, extension and display name for OLE Package. Following code example shows how to use these properties.

Document document = new Document();
DocumentBuilder builder = new DocumentBuilder(document);
byte[] bs = File.ReadAllBytes(@"c:\temp\input.zip");
using (Stream stream = new MemoryStream(bs))
{
    Shape shape = builder.InsertOleObject(stream, "Package", true, null);
    OlePackage olePackage = shape.OleFormat.OlePackage;
    olePackage.FileName = "FileName.zip";
    olePackage.DisplayName = "DisplayName.zip";
    document.Save(@"c:\temp\Zip.docx");
}
