adding to List (of Byte()) - vb.net

Question

The function requires a generic list (of Byte()) to be passed as agrs and I just cannot seem to get anything to add to this list.I require printdata(0) & (1) adding to it.
Dim printdata(1) As String
labelname = "WasNow"
printdata(0) = "9,99"
printdata(1) = "6.99"
Dim args = New List(Of Byte())
args.Add(Convert.ToByte(printdata))
ApplicationContext.CurrentDevice.Printer.Print(labelname, 1, args)
Frmscanprint.Show()
This is the working C# version of the code with only one item to add.
private void printButton_Click(object sender, EventArgs e)
{
try
{
this.printNumber++;
var args = new List<byte[]>() { Encoding.ASCII.GetBytes(string.Format(CultureInfo.InvariantCulture, "Test #{0}", this.printNumber)) };
if (!ApplicationContext.AllDevicesSelected)
{
ApplicationContext.CurrentDevice.Printer.Print("SamplePrint", 1, args);
}
else
{
PrintSampleForEachDevice("SamplePrint", 1, args);
}
}
}

The C# example you provided gets a single string and converts it to a byte array, assigning this array to the newly created list.
Your code is not doing the same thing. You are trying to convert a string array to a byte array. This conversion type is not allowed by the method you are trying to use. Even if it is possible, the result would be a single byte array with the entire content and not an array of byte array.
If you want to do the same thing as the C# code does, you shoud do it for each itm from your string array a time.
If you want to do the same thing as the C# code, you shoud do it for each single item from your string array. For example:
For Each item As String In printdata
args.Add(Encoding.ASCII.GetBytes(item))
