使用 C# 将文件简单上传到 Rapidshare 账户的方法

• 下载源代码和演示程序 [.NET 2.0 - VS2008] - 26.26 KB

引言

通过使用这个类，您可以轻松地将文件上传到 Rapidshare.com。

使用 RapidShare，您可以轻松且安全地发送大文件。

这个类支持以下类型的 Rapidshare 帐户：

• 高级帐户 (type = 1)
• 收藏家帐户 (type = 2)
• 免费用户 (type = 0)

选择文件并上传后，您应该在结果面板中看到两个链接，一个用于下载，另一个用于从 Rapidshare.com 删除文件。

Using the Code

您可以在演示应用程序的源代码中查看该类的完整用法。

对于这个应用程序，我使用的是 Rapidshare 版本 1 API（原始 API 是用 Perl 编写的）。

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();

            }//Get Response from Rapidshare and Return the Links.
