Comment convertir des données ASCII en EBCDIC en C#?

Question

J'ai lu à propos de la conversion de ASCII en EBCDIC en utilisant ce lien;
Convert String from ASCII to EBCDIC in Java?

Mais ceci est en java. Ma condition est en C# .Net.

Alors pouvez-vous s'il vous plaît m'aider avec cela?

Merci & Cordialement,
Krishna Kumar

Answer 1

Here's an implementation (par Skeet) @ Jon pourraient vous être utiles.

Answer 2

Essayez comme ci-dessous le 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, 
16, 17, 18, 19, 60, 61, 50, 38, 24, 25, 63, 39, 28, 29, 30, 31, 
64, 79,127,123, 91,108, 80,125, 77, 93, 92, 78,107, 96, 75, 97,

}; 

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; 
}

Answer 3

J'ai essayé le code ci-dessus, et j'ai trouvé que cela ne fonctionnait pas pour moi.

Par exemple, '04' (0x3034) ascii traduit en 0x00f000f4 ebcdic. Le problème semblait être l'encodage. Joué avec plusieurs approches pour changer cela, mais finalement trouvé la meilleure solution était la plus élémentaire. Au lieu d'utiliser Convert.ToChar, j'ai branché la valeur hexadécimale dans le tableau.

S'il vous plaît voir ci-dessous:

static byte[] ASCIItoEBCDIC(string asciiString) 
{ 
    byte[] asciiToEbcdicTable = new byte[256] {
