Adds a CRLF to EDI files replacing the ~, ... or any other line terminator.
I have searched online for a solution to convert any given line terminator to CRLF; while I have found a way to do this in perl script it only worked for
the ~ and not the ... terminators. So I was on a mission to find a way to do this in .NET and now have come up with an easy solution to get it done.
Using the code
The code is simple to use. Replace path with the path of the edi files to be parsed and the code will loop through each record and replace the line terminator with a CRLF.
Dim di As New DirectoryInfo(path)
Dim fiArr As FileInfo() = di.GetFiles()
Dim fri As FileInfo
For Each fri In fiArrDim vBinFile As String = path & fri.Name.Trim
Dim fs As New FileStream(vBinFile, FileMode.Open)
Dim b(fs.Length - 1) As Byte
fs.Read(b, 0, b.Length - 1)
fs = Nothing
Dim myData As String = System.Text.ASCIIEncoding.ASCII.GetString(b)
Dim str As String = myData.Trim
Dim terminator As Char
terminator = str.Chars(105)
myData = myData.Replace(terminator, vbCrLf)
Dim fw As New IO.StreamWriter(path & fri.Name.Trim.Replace(".txt", "_.txt"), False)
Points of Interest
I have found that if you open the file in binary mode then try replacing the terminator with 0d0a then writing back to the file in binary mode,
it will truncate the beginning of each character.
