Question

How can i convert this VBNet code into C#? (ByteToImage is a User Defined Function use to convert Byte Array into Bitmap.

Dim Bytes() As Byte = CType(SQLreader("ImageList"), Byte())
picStudent.Image = jwImage.ByteToImage(Bytes)

I tried

byte[] Bytes = Convert.ToByte(SQLreader("ImageList")); // Error Here
picStudent.Image = jwImage.ByteToImage(Bytes);

but it generates an error saying: Cannot implicitly convert type 'byte' to 'byte[]'

What i am doing is basically converting an Image from database to byte array and displaying it on the picturebox.

Answer 1

The problem is you have an array of bytes (byte[] in C# and Byte() in VB.Net) but the Convert.ToByte call just returns a simple byte. To make this work you need to cast the return of SQLreader to byte[].

There is no perfect analogous construct for CType in C# but a simple cast here should do the trick

byte[] Bytes = (byte[])SQLreader("ImageList");
