How to convert ASCII data to EBCDIC in C#?

I read about conversion of ASCII to EBCDIC using this link;

Convert String from ASCII to EBCDIC i开发者_JAVA技巧n Java?

But this is in java. My requirement is in C#.Net.

So can you please help me with this?

Thanks & Regards,

Here's an implementation (by @Jon Skeet) you might find useful.

I tried the above code, and found it did not work for me.

For example, '04' (0x3034) ascii translated to 0x00f000f4 ebcdic. Problem seemed to be the encoding.

Played with several approches to change this, but finally found the best solution was the most basic. Instead of using Convert.ToChar, I plugged the hex value into the array.

Please see following:

static byte[] ASCIItoEBCDIC(string asciiString)
{
    byte[] asciiToEbcdicTable = new byte[256] {
        0x00,0x01,0x02,0x03,0x37,0x2D,0x2E,0x2F,0x16,0x05,0x25,0x0B,0x0C,0x0D,0x0E,0x0F,
        0x10,0x11,0x12,0x13,0x3C,0x3D,0x32,0x26,0x18,0x19,0x3F,0x27,0x1C,0x1D,0x1E,0x1F,
        0x40,0x5A,0x7F,0x7B,0x5B,0x6C,0x50,0x7D,0x4D,0x5D,0x5C,0x4E,0x6B,0x60,0x4B,0x61,
        0xF0,0xF1,0xF2,0xF3,0xF4,0xF5,0xF6,0xF7,0xF8,0xF9,0x7A,0x5E,0x4C,0x7E,0x6E,0x6F,
        0x7C,0xC1,0xC2,0xC3,0xC4,0xC5,0xC6,0xC7,0xC8,0xC9,0xD1,0xD2,0xD3,0xD4,0xD5,0xD6,
        0xD7,0xD8,0xD9,0xE2,0xE3,0xE4,0xE5,0xE6,0xE7,0xE8,0xE9,0xBA,0xE0,0xBB,0xB0,0x6D,
        0x79,0x81,0x82,0x83,0x84,0x85,0x86,0x87,0x88,0x89,0x91,0x92,0x93,0x94,0x95,0x96,
        0x97,0x98,0x99,0xA2,0xA3,0xA4,0xA5,0xA6,0xA7,0xA8,0xA9,0xC0,0x4F,0xD0,0xA1,0x07,
        0x20,0x21,0x22,0x23,0x24,0x15,0x06,0x17,0x28,0x29,0x2A,0x2B,0x2C,0x09,0x0A,0x1B,
        0x30,0x31,0x1A,0x33,0x34,0x35,0x36,0x08,0x38,0x39,0x3A,0x3B,0x04,0x14,0x3E,0xFF,
        0x41,0xAA,0x4A,0xB1,0x9F,0xB2,0x6A,0xB5,0xBD,0xB4,0x9A,0x8A,0x5F,0xCA,0xAF,0xBC,
        0x90,0x8F,0xEA,0xFA,0xBE,0xA0,0xB6,0xB3,0x9D,0xDA,0x9B,0x8B,0xB7,0xB8,0xB9,0xAB,
        0x64,0x65,0x62,0x66,0x63,0x67,0x9E,0x68,0x74,0x71,0x72,0x73,0x78,0x75,0x76,0x77,
        0xAC,0x69,0xED,0xEE,0xEB,0xEF,0xEC,0xBF,0x80,0xFD,0xFE,0xFB,0xFC,0xAD,0xAE,0x59,
        0x44,0x45,0x42,0x46,0x43,0x47,0x9C,0x48,0x54,0x51,0x52,0x53,0x58,0x55,0x56,0x57,
        0x8C,0x49,0xCD,0xCE,0xCB,0xCF,0xCC,0xE1,0x70,0xDD,0xDE,0xDB,0xDC,0x8D,0x8E,0xDF};

    byte[] ebcdicBinary = new byte[asciiString.Length];
    for (int pos = 0; pos < asciiString.Length; ++pos)
    {
        int ebcdicIndex = asciiString[pos];
        ebcdicBinary[pos] = asciiToEbcdicTable[ebcdicIndex];
    }
    return ebcdicBinary;
}

Try like below code

public string ConvertASCIItoEBCDIC(string strASCIIString)
{
int[] a2e = new int[256]{
0, 1, 2, 3, 55, 45, 46, 47, 22, 5, 37, 11, 12, 13, 14, 15,

};

char chrItem = Convert.ToChar("0");
StringBuilder sb = new StringBuilder();
for (int i = 0; i < strASCIIString.Length; i++)
{
    try
    {
       chrItem = Convert.ToChar(strASCIIString.Substring(i, 1));
       sb.Append(Convert.ToChar(a2e[(int)chrItem]));
     }
    catch (Exception ex)
    {
       Console.WriteLine(ex.Message);
       return string.Empty;
     }
}
string result = sb.ToString();
sb = null;
return result;
}
