Question

我读到了使用此链接将ASCII转换为EBCDIC;
Convert String from ASCII to EBCDIC in Java?

但这是在java中。我的要求是在C＃.Net。

那么请你帮帮我吗？

谢谢＆amp;问候，

Answer 1

Here's an implementation（@Jon Skeet）你可能会觉得很有用。

Answer 2

我尝试了上面的代码，发现它对我不起作用。

例如，＆＃39; 04＆＃39; （0x3034）ascii转换为0x00f000f4 ebcdic。问题似乎是编码。

玩了几个approches来改变这个，但最后发现最好的解决方案是最基本的。我没有使用Convert.ToChar，而是将十六进制值插入数组中。

请参阅以下内容：

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,

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

尝试以下代码

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,

64, 79,127,123, 91,108, 80,125, 77, 93, 92, 78,107, 96, 75, 97,

32, 33, 34, 35, 36, 21, 6, 23, 40, 41, 42, 43, 44, 9, 10, 27,
48, 49, 26, 51, 52, 53, 54, 8, 56, 57, 58, 59, 4, 20, 62,225,
65, 66, 67, 68, 69, 70, 71, 72, 73, 81, 82, 83, 84, 85, 86, 87,

118,119,120,128,138,139,140,141,142,143,144,154,155,156,157,158,
159,160,170,171,172,173,174,175,176,177,178,179,180,181,182,183,
184,185,186,187,188,189,190,191,202,203,204,205,206,207,218,219,

};

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;
}
