我的程序代码:

公共字符串QUploadToUlozto(字符串FilePath，字符串用户名，
字符串密码，整数AccountType)
{
FileSystemInfo _file = new FileInfo(FilePath);
DateTime dateTime2 = DateTime.Now;
long l2 = dateTime2.Ticks;
字符串s1 ="----------" + l2.ToString("x");
System.Net.HttpWebRequest httpWebRequest = GetWebrequest(s1);
使用(System.IO.FileStream fileStream = new FileStream(_file.FullName，
FileMode.Open，FileAccess.Read，FileShare.Read))
{//设置上传标题
byte [] bArr1 = Encoding.ASCII.GetBytes("\ r \ n--" + s1 +"\ r \ n");
字符串s2 = GetRequestMessage(s1，_file.Name，用户名，密码，AccountType);
byte [] bArr2 = Encoding.UTF8.GetBytes(s2);
流memStream = new MemoryStream();
memStream.Write(bArr1，0，bArr1.Length);
memStream.Write(bArr2，0，bArr2.Length);
字节[]缓冲区=新字节[1024];
int bytesRead = 0;//将文件读入memStream.
while((bytesRead = fileStream.Read(buffer，0，buffer.Length))！= 0)
{
memStream.Write(buffer，0，bytesRead);

}
httpWebRequest.ContentLength = memStream.Length;
fileStream.Close();

流requestStream = httpWebRequest.GetRequestStream();
//将文件从memStream发送到Rapidshare.com
memStream.Position = 0;

memStream.Read(tempBuffer，0，tempBuffer.Length);
memStream.Close();
requestStream.Write(tempBuffer，0，tempBuffer.Length);
requestStream.Close();
}
字符串tm =";
使用(Stream stream = httpWebRequest.GetResponse().GetResponseStream())
使用(StreamReader streamReader = new StreamReader(stream))
{
tm = streamReader.ReadToEnd();

}//从Rapidshare获取响应并返回链接.
返回tm;
}

私有字符串GetRequestMessage(字符串边界，字符串FName，
字符串用户名，字符串密码，整数AccountType)
{

对不起...我错误的原始代码在这里:使用C#简单地将文件上传到Rapidshare帐户方法 [ ^ ]而我很绝望，因为我不知道如何制作，或者不知道有人可以将更好的代码上传到不同的服务器吗?谢谢;)

emm sorry...my bad, original code is here : Simple Upload File to Rapidshare Account Method using C#[^] and I am desperate, because I dont know how make it, or know someone a better code for upload to different servers? thanks ;)
