Formating String for a serial number type
Question:
Tag: vb.net,format,string-formatting
I wish to format a string for display as a serial number e.g.
abc12345d67890
to
00ab-c123-45d6-7890
if it was numbers i could
DataGridView.Columns(2).DefaultCellStyle.Format = "0000-0000-0000-0000"
MaskedTextBox1.Mask = ("0000-0000-0000-0000")
but if it is a String this doesn't work. Can anyone help me in a direction?
The information is displayed in 16 char for easy reading and understanding some values are 2AFHY89 and must be recorded as such
It is displayed several different ways/times e.g. label, Textbox, DataGridView,
I don't understand IFormatProvider, ICustomFormatter so if the value did not have [a-z] i could just use the above example("0000-0000-0000-0000")
I wish to use a format NOT alter the data stored both examples are not a format just editing the stored data.
Answer:
You can pad the serial number with zeros to get the full 16 characters, then split it into 4 character parts and then join the parts with "-" between them.
Dim serial As String = "abc12345d67890"
serial = serial.PadLeft(16, "0"c)
Dim parts(3) As String
parts(3) = serial.Substring(serial.Length - 3)
parts(2) = serial.Substring(serial.Length - 7, 4)
parts(1) = serial.Substring(serial.Length - 11, 4)
parts(0) = serial.Substring(0, serial.Length - 12)
Dim formattedSerial As String = String.Join("-", parts)
