Vb.net 将值声明为对象？

在C#中，我们是这样做的

这使得imageData变量成为对象

但是如何在Visual Basic中实现这一点

Dim imageData As byte() = new Byte()
SqlCom.Parameters.Add(new SqlParameter("@ImageData", ?? ) <-----What Should i do here?

Dim imageData As byte（）=新字节（）
添加（新的SqlParameter（“@ImageData”），你想要这样的东西。

Dim imageData As Byte() =  New Byte() 
SqlCom.Parameters.Add(New SqlParameter("@ImageData",CType(imageData, Object)))

conn.Open() 
Dim cmd As SqlCommand = New SqlCommand("SELECT PhotoID From Photo " & str8 & " And Photo = @Photo", conn) 
cmd.Parameters.AddWithValue("@Photo", CType(Photo, Object)) 
Dim adapter As SqlDataAdapter = New SqlDataAdapter() 
adapter.SelectCommand = cmd 
adapter.Fill(table) <------when approach this line 
PhotoID = table.Rows(0)("PhotoID") 

Dim imageData As Byte() =  New Byte() 
SqlCom.Parameters.Add(New SqlParameter("@ImageData",CType(imageData, Object)))
