How to convert Extended ASCII to decimal in Windows Forms C#?

Question

I am writing a windows application. am facing problem in converting Extended ASCII[128-256] to its decimal equivalent.

when i receive the extended ASCII say for example "Œ" from a jar file, it comes into C# application like this : �.

Can i know how to convert this to its decimal equivalent [i.e] 140.

string textToConvert = "Œ";
Encoding iso8859 = Encoding.GetEncoding("iso-8859-1");
Encoding unicode = Encoding.Unicode;
byte[] srcTextBytes = iso8859.GetBytes(textToConvert);
byte[] destTextBytes = Encoding.Convert(iso8859,unicode, srcTextBytes);
char[] destChars = new char[unicode.GetCharCount(destTextBytes, 0, destTextBytes.Length)];
unicode.GetChars(destTextBytes, 0, destTextBytes.Length, destChars, 0);
System.String szchar = new System.String(destChars);

MessageBox.Show(szchar);

Please help me. How should i proceed??

I think you are looking for something like this

    String str="œ";
    var bytes = Encoding.GetEncoding("Windows-1252").GetBytes(s);
    string binStr = string.Join("", bytes.Select(b => Convert.ToString(b, 2)));
    int decimalEquivalent=Convert.ToInt32(binStr,2);
    Console.WriteLine(decimalEquivalent);

this is working for ASCII [128-255]
