[具有十六进制值的c＃WebConfig应用程序设置

Question

我有以下c＃代码行：

Rfc2898DeriveBytes pdb = new Rfc2898DeriveBytes(EncryptionKey, new byte[] { 0x49, 0x76, 0x61, 0x6e, 0x20, 0x4d, 0x65, 0x64, 0x76, 0x65, 0x64, 0x65, 0x76 });

我需要在web.config中存储十六进制值列表：

<add key="BytesVector" value="0x49, 0x76, 0x61, 0x6e, 0x20, 0x4d, 0x65, 0x64, 0x76, 0x65, 0x64, 0x65, 0x76" />

然后使用这样的值：

 var vector = ConfigurationManager.AppSettings["BytesVector"].ToString();

 Rfc2898DeriveBytes pdb = new Rfc2898DeriveBytes(EncryptionKey, new byte[] { someParsingHere(vector) });

任何线索？

Answer 1

这里是一个例子：

string s = "0x49, 0x76, 0x61, 0x6e, 0x20, 0x4d, 0x65, 0x64, 0x76, 0x65, 0x64, 0x65, 0x76";
var list = s.Split(',');

byte[] bytes = new byte[list.Length];
for(int i=0; i<list.Count(); i++)
{
    bytes[i] = Convert.ToByte(number.Trim(), 16);
}
