post提交数据流，欢迎大家一起学习

代码如下，功能：从本地读取一张图片转成byte然后post，现在的情况是我定义一个string转换成byte就可以post，但是读取文件的post就不可以。注释我已经在程序里写的很详细了，程序也不长，希望大家指点。编码问题我换过默认和ascii都不能解决，读取图片的程序没有问题。多谢大家，解决问题给分，马上结贴。

代码如下：
Encoding encode = System.Text.Encoding.GetEncoding("utf-8");

string url = "http://localhost:21240/ChangeHair/Receive.aspx";
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);

//定义一个string，测试
string s = "要提交的数据";

//读取一个图片，测试
FileStream fs = new FileStream(Server.MapPath("~/1.jpg"), System.IO.FileMode.Open, System.IO.FileAccess.Read);
byte[] filecontent = new byte[fs.Length];
fs.Read(filecontent, 0, filecontent.Length);
fs.Close();
fs.Dispose();

//将图片流post，不成功
byte[] requestBytes = System.Text.Encoding.Convert(Encoding.ASCII, Encoding.ASCII, filecontent, 0, filecontent.Length);

//将文本流post 成功
// byte[] requestBytes = System.Text.Encoding.Default.GetBytes(s);

req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
req.ContentLength = requestBytes.Length;
Stream requestStream = req.GetRequestStream();
requestStream.Write(requestBytes, 0, requestBytes.Length);
requestStream.Close();

// 写入数据库
string strConn = ConfigurationSettings.AppSettings["ConnectionString"];
SqlConnection myConnection = new SqlConnection(strConn);
SqlCommand myCommand = new SqlCommand("sp_person_isp", myConnection);
myCommand.CommandType = CommandType.StoredProcedure;

myCommand.Parameters.Add("@PersonEmail", SqlDbType.VarChar, 255).Value = PersonEmail;
myCommand.Parameters.Add("@PersonName", SqlDbType.VarChar, 255).Value = PersonName;
myCommand.Parameters.Add("@PersonSex", SqlDbType.Char, 1);
if(sexMale.Checked)
myCommand.Parameters["@PersonSex"].Value = "M";
else
myCommand.Parameters["@PersonSex"].Value = "F";
myCommand.Parameters.Add("@PersonDOB", SqlDbType.DateTime).Value = PersonDOB;
myCommand.Parameters.Add("@PersonImage", SqlDbType.Image).Value = myImage;
myCommand.Parameters.Add("@PersonImageType", SqlDbType.VarChar, 255).Value = ImageType;

try
{
myConnection.Open();
myCommand.ExecuteNonQuery();
myConnection.Close();
Response.Write("添加成功！");
