Gets or sets the type of encoding to use when generating the barcode.
Note that BarCodeType.None is not a valid value for this property.
The following sample shows how to use the BarCodeType property to encode the value "123456" as a Code39-encoded barcode:
RenderBarCode rbc = new RenderBarCode();
rbc.BarCodeType = BarCodeType.Code39;
rbc.Text = "123456";
doc.Body.Children.Add(rbc);
