或者，用sql语句读取

Dim cmd As SQLCommand = new SQLCommand()
cmd.ConnectionName = "SqlServerDB"
cmd.CommandText = "se lect 照片列 from 员工表 where 姓名 = '张三'"

Dim imageByte() As Byte = cmd.ExecuteScalar()    '查询数据，并存入字节数组

Dim ms As New IO.MemoryStream(imageByte)       '将字节数组转换为二进制流
Dim image As Image = Image.FromStream(ms)      '将二进制流转换为图片
e.Form.Controls("PictureBox1").Image = image      '显示图片
