Convert EBCDIC to ASCII and vice versa
-
Hi, In my C# application, I need to convert EBCDIC data to ASCII. This EBCDIC data is stored as BLOB type in Teradata. This data also has packed decimals in it. I tried the code i found on internet, which simply converts EBCDIC to ASCII. In that there a interger array of 256 characters only. But the characters which i need to convert, char chrItem = Convert.ToChar(strEbcidic.Substring(i, 1)); returns number much higher then 256. So i get 'index out of bound of array exception'. The EBCDIC characters include ' ÁõÁõöôùô@@@@ðóùòùùðñ@ððððð' also. Could any one please help me out here? Thanks, Deepa

I think the problem may be that your input is not EBCDIC - ebcdic is an 8-bit code so only has characters 000 to 255. Wiki on EBCDIC[^]

Hi, Yes, none of these characters in the file are in the 255 codes of EBCDIC. As i had mentioned earlier, the file from the BLOB, contains packed decimal also. Are you sure its not EBCDIC, when i do .ToCharArray() i get like: [0]: 22909 '好' [1]: 8224 '†' [2]: 8256 '⁀' [3]: 8592 '←' [4]: 879 'ͯ' [5]: 12629 'ㅕ' [6]: 16527 '䂏' [7]: 16448 '䁀' [8]: 16448 '䁀' [9]: 16448 '䁀' [10]: 16448 '䁀' [11]: 16448 '䁀' [12]: 16448 '䁀' [13]: 65533 '�' [14]: 49605 '쇅' [15]: 16601 '䃙' [16]: 16448 '䁀' [17]: 16448 '䁀' [18]: 16448 '䁀' [19]: 16448 '䁀' [20]: 16448 '䁀' [21]: 16448 '䁀' [22]: 16448 '䁀' [23]: 62448 '' [24]: 63216 '' [25]: 63220 '' [26]: 63473 '' [27]: 63216 '' [28]: 62451 '' [29]: 61689 '' [30]: 54769 '헱' [31]: 16448 '䁀' [32]: 16448 '䁀' [33]: 16448 '䁀' [34]: 16448 '䁀' So their character codes are greater then 255. How to resolve this?

The problem is that chars in .NET are Unicode, which is generally two bytes. Using a byte array instead of a char array might solve your problem.

I highly recommend using Jon Skeet's EBCDIC encoding library[^] We have been using this for years. You basically just set up Encoding objects and pass them into Stream objects. Granted, this is VB.NET code, but it should still make sense:
Dim inputEncoding As Encoding = EbcdicEncoding.GetEncoding("EBCDIC-US")
Dim outputEncoding = Encoding.ASCII
Dim inputReader As StreamReader
Dim outputWriter As StreamWriter
inputReader = New StreamReader(inputFile, inputEncoding)
outputWriter = New StreamWriter(outputFile, False, outputEncoding)I don't claim to be a know it all, for I know that I am not...
I usually have an answer though.

Try This #region public static byte[] ConvertAsciiToEbcdic(byte[] asciiData) public static byte[] ConvertAsciiToEbcdic(byte[] asciiData) { // Create two different encodings. Encoding ascii = Encoding.ASCII; Encoding ebcdic = Encoding.GetEncoding("IBM037"); //Retutn Ebcdic Data return Encoding.Convert(ascii, ebcdic, asciiData); } #endregion #region public static byte[] ConvertEbcdicToAscii(byte[] ebcdicData) public static byte[] ConvertEbcdicToAscii(byte[] ebcdicData) { // Create two different encodings. Encoding ascii = Encoding.ASCII; Encoding ebcdic = Encoding.GetEncoding("IBM037"); //Retutn Ascii Data return Encoding.Convert(ebcdic, ascii, ebcdicData); } #endregion
