请各位发个邮件中quoted printable的编码函数，c#的，不要解码，只要编码的~

如题，谢谢了~

附件里可以指定编码方式，参考：

Attachment vAttachment = new Attachment("yourfile");
vAttachment.TransferEncoding = System.Net.Mime.TransferEncoding.QuotedPrintable;

先谢过，可是我要字符串转化为qp编码呢~

[王集鹄]

//硬写一个也不难...
using System.Collections;
using System.Globalization;

public string QuotedPrintableEncode(string AText) // QP编码
{
string Result = "";
byte[] vBuffer = Encoding.Default.GetBytes(AText);
foreach(byte vByte in vBuffer)
// 可见字符并非"="(#61)
if ((vByte >= 33 && vByte <= 60) || (vByte >= 62 && vByte <= 126))
Result += (char)vByte;
else Result += "=" + vByte.ToString("X2");
return Result;
}

public static string QuotedPrintableDecode(string ACode) // 解码
{
ArrayList vBuffer = new ArrayList();

for(int i = 0; i < ACode.Length; i++)
{
if (ACode[i] == '=')
{
i++;
if (ACode[i] != '\r')
{
byte vByte;
if (byte.TryParse(ACode.Substring(i, 2),
NumberStyles.HexNumber, null, out vByte))
vBuffer.Add(vByte);
}
i++;
}
else if (ACode[i] != '\n') vBuffer.Add((byte)ACode[i]);
}
return Encoding.Default.GetString((byte[])vBuffer.ToArray(typeof(byte)));
}

private void button1_Click(object sender, EventArgs e)
{
Text = QuotedPrintableDecode(QuotedPrintableEncode("zswang 路过"));
}
