如何使用vb.net从数据库获取二进制图像

Question

Convert binary to image using VB.NET from database. I have stored images as binary format in SQL database. How to retrieve those value to image using vb.net

bytes = CType(dt.Rows(0)("Data"), Byte())
ImgPrv.ImageUrl = bytes

Answer 1

I would suggest converting the bytes to a Base64 string and applying that to the image url:

bytes = CType(dt.Rows(0)("Data"), Byte())
Dim base64String As String = Convert.ToBase64String(bytes, 0, bytes.Length)
ImgPrv.ImageUrl = "data:image/png;base64," & base64String
