Add Blob data type objects in Oracle

I am wondering how to assign values to Blob objects.

Image bb = Bitmap. FromFile (@ "f: \ abc. Gif"); // define the Image position
System. IO. MemoryStream MS = new System. IO. MemoryStream ();
Bb. Save (MS, System. Drawing. Imaging. ImageFormat. Gif); // select the corresponding format based on the Image Type

This is the case when calling

Emp. PICTURE = ms. GetBuffer (); // gets the unsigned array that creates the stream.

In this way, we can test whether the Blob data storage process is correct.
