//把流转化为文件
public static void StreamToFile(Stream stream, string filepath)
{
byte[] bytes = StreamToBytes(stream);
FileStream fileStream = new FileStream(filepath, FileMode.Create);
fileStream.Write(bytes, 0, bytes.Length);

fileStream.Close();
}
//把流转化为字节数组
public static byte[] StreamToBytes(Stream stream)

return memoryStream.ToArray();
}
//把流转化为Base64字符串
public static string StreamToString(Stream stream)
{
byte[] buffer = new byte[stream.Length];

string base64string = Convert.ToBase64String(buffer);

}
//把Base64字符串转化为流
pubblic static Stream StringToStream(string str)
{
byte[] bt = Convert.FromBase64String(str);
System.IO.MemoryStream stream = new System.IO.MemoryStream(bt);
}
求补充。。。。。。。。。。。。。。
