Back

Demonstrates how to load a file into a byte array.

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

        Dim fInfo As New FileInfo("byteArray.dat")

        Dim numBytes As Long = fInfo.Length

        Dim fStream As New FileStream("byteArray.dat", FileMode.Open, FileAccess.Read)

        Dim br As New BinaryReader(fStream)

        Dim data As Byte() = br.ReadBytes(CInt(numBytes))

        ' Show the number of bytes in the array.
        Label1.Text = Convert.ToString(data.Length)

        br.Close()

        fStream.Close()

    End Sub
