哪位大侠知道怎样在pop3中解码quoted-printable？

Question

string DeCode(string input)
{
System.Text.Encoding encoding = System.Text.Encoding.GetEncoding("gb2312");
string temp;
int cnt=0;
for(int i=0;i!=-1;i=input.IndexOf("=",i+1))
cnt++;
byte[] b=new byte[cnt];
cnt=0;
for(int i=0;i!=-1;i=input.IndexOf("=",i+1))
{
temp=input.Substring(i+1,2);
b[cnt++]=byte.Parse(temp,System.Globalization.NumberStyles.HexNumber);
}
return encoding.GetString(b);
}

Answer 1

说明
只能对诸如=A3=AC=C4=E3=BA=C3=A3=A1=A1=A1=A1=A1=A1=A1=A1=A1=A1=A1=A1=A1=A1=A1=A1=A1=A1=A1=A1=A1=D6=C2=C0=F1=A3=A1=A1=A1=A1=A1=A1=A1=A1=A1=A1=A1=A1=A1=A1=A1=A1=A1=CC=EF=C4=BE=C1=D6=A1=A1=A1=A1=A1=A1=A1=A1=A1=A1=A1=A1=A1=A1=A1=A1这样的进行解码
若有其他内容如英文字符，可能出错

Answer 2

chasn(chasn)大侠：不行啊，解不出来！b[cnt++]=byte.Parse(temp,System.Globalization.NumberStyles.HexNumber);总是上面这句出错：输入字符串的格式不正确。我检查过无数次，字符串绝对没错，我甚至先把原码转成string[]：
bt[i]=byte.Parse(str[i],System.Globalization.NumberStyles.HexNumber);也不行，你用这段代码解出过吗？

Answer 3

已解决，chasn(chasn) 的代码是正确的！
