Simple Upload File to Rapidshare Account Method using C#

• Download source and demo [.NET 2.0 - VS2008] - 26.26 KB

Introduction

By using this class, you can easily upload your files to Rapidshare.com.

With RapidShare, you can send big files easily and in a secure manner.

This class supports the following type of Rapidshare accounts:

• Premium accounts (type = 1)
• Collector's accounts (type = 2)
• Free users (type = 0)

After Selecting the file and uploading, you should see two links in the result Panel, one for downloading and one for deleting the file from Rapidshare.com.

Using the Code

You can see the full usage of this class in the source of the demo application.

For this application, I'm using Rapidshare version 1 API (the original API is made by Perl).

class QRapidshare
    {
        public string QUploadToRapidshare(string FilePath, string username,
            string password, int AccountType)
        {
            FileSystemInfo _file = new FileInfo(FilePath);
            DateTime dateTime2 = DateTime.Now;
            long l2 = dateTime2.Ticks;
            string s1 = "----------" + l2.ToString("x");
            System.Net.HttpWebRequest httpWebRequest = GetWebrequest(s1);
            using (System.IO.FileStream fileStream = new FileStream(_file.FullName,
                FileMode.Open, FileAccess.Read, FileShare.Read))
            {//Set Headers for Uploading
                byte[] bArr1 = Encoding.ASCII.GetBytes("\r\n--" + s1 + "\r\n");
                string s2 = GetRequestMessage(s1, _file.Name, username, password,
                    AccountType);
                byte[] bArr2 = Encoding.UTF8.GetBytes(s2);
                Stream memStream = new MemoryStream();
                memStream.Write(bArr1, 0, bArr1.Length);
                memStream.Write(bArr2, 0, bArr2.Length);
                byte[] buffer = new byte[1024];
                int bytesRead = 0;//Read File into memStream.
                while ((bytesRead = fileStream.Read(buffer, 0, buffer.Length)) != 0)
                {
                    memStream.Write(buffer, 0, bytesRead);

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

                Stream requestStream = httpWebRequest.GetRequestStream();
//Send File from memStream to Rapidshare.com
                memStream.Position = 0;
                byte[] tempBuffer = new byte[memStream.Length];
                memStream.Read(tempBuffer, 0, tempBuffer.Length);
                memStream.Close();
                requestStream.Write(tempBuffer, 0, tempBuffer.Length);
                requestStream.Close();
            }

                tm = streamReader.ReadToEnd();

//You can use this class in .NET Web, Window, WebService,...

In the next version, I want to add an Upload Speed Control and Progress Bar.

You can upload up to 2000 MB file to your Premium account, and up to 200 MB for Collectors account and Free users.

Points of Interest

You can also use this method for your web applications and dynamically upload your files to your Rapidshare.com account.
