ASCIIEncoding在Windows Phone 7的

问题描述

有没有在Windows中使用ASCIIEncoding办法Phone 7的？

Is there a way to use ASCIIEncoding in Windows Phone 7?

除非我做错事 Encoding.ASCII 不存在，我需要它的C＃ - > PHP加密（如PHP只能在SHA1使用ASCII加密）。

Unless I'm doing something wrong Encoding.ASCII doesn't exist and I'm needing it for C# -> PHP encryption (as PHP only uses ASCII in SHA1 encryption).

有什么建议？

推荐答案

这是很容易实现自己，统一code从不与ASCII codeS搞砸：

It is easy to implement yourself, Unicode never messed with the ASCII codes:

    public static byte[] StringToAscii(string s) {
        byte[] retval = new byte[s.Length];
        for (int ix = 0; ix < s.Length; ++ix) {
            char ch = s[ix];
            if (ch <= 0x7f) retval[ix] = (byte)ch;
            else retval[ix] = (byte)'?';
        }
        return retval;
    }
