Blob Field In Query String

I had been using this way for while, and it seems it work fine with char and numbers.
Dim MyVar1 as String = "Hello"
Dim MyVar2 as Integer = 1
Dim MySQL = "Select * from table where field1 = '<field1>' and Field2 = <field2>"
MySQL = MySQL.Replace("<field1>",MyVar1).Replace("<field2>",MyVar2)
msgbox(MySQL)

But, when I have to deal with blob field, where I store "wav file" for example, I had to read it as array of bytes, and the only way I find to insert the array of bytes in my query string is by using the command.AddParameter
Dim myfile As System.IO.FileStream = System.IO.File.OpenRead("full_wav_file_path")
Dim myArray(myfile.Length) As Byte
myfile.Read(myArray, 0, (myfile.Length))
[Code] .....
Is there another way to insert it without addParameter?
