发邮件窗体【支持编辑邮件模板，使用wse多线程上传附件及发邮件（带附件）】以及在服务器端自动发邮件

        这是前段时间做的一个邮件客户端，支持自定义模板（模板是内置的，固定好了)   
       其中配置模板的xml
<?xml version="1.0" encoding="utf-8" ?>
<TemplateConfigure>
  <BaseDirectory>EmailTemplate</BaseDirectory>

  <TemplateDirectory>模板</TemplateDirectory>

  <AttachDirectory>附件</AttachDirectory>
       <Template>
    <EmailType>DrawFail</EmailType>
    <TemplateName>支取缺材料.htm</TemplateName>
 <FileName>DrawFail.htm</FileName>
  </Template>

  <Attach>
    <AttachType>SheBaoBJBack</AttachType>
    <FileName>社保报减退回原因释义表.doc</FileName>
  </Attach>

  </TemplateConfigure>
读取配置文件的代码为

  private   void  ParseConfiguration()
         {
            try
            {
                XmlSerializer serializer = new XmlSerializer(typeof(TemplateConfigure));
                using (Stream stream = this.GetType().Assembly.
                    GetManifestResourceStream(this.GetType(), "EmailTemplate.EmailType.xml"))
                {
                    templateConfigure = serializer.Deserialize(stream) as TemplateConfigure;
                    templateConfigure.TemplateDirectory = GetDirectory(templateConfigure.TemplateDirectory);
                    templateConfigure.AttachDirectory = GetDirectory(templateConfigure.AttachDirectory);
                }
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }

上传文件使用了wse3.0（web service Enhancements ）,使用backgroudworker多线程上传   
启动服务器段wse需在web.config里添加
<webServices>
      <soapServerProtocolFactory type="Microsoft.Web.Services3.WseProtocolFactory, Microsoft.Web.Services3, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
      <soapExtensionImporterTypes>
        <add type="Microsoft.Web.Services3.Description.WseExtensionImporter, Microsoft.Web.Services3, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
      </soapExtensionImporterTypes>
    </webServices>

<microsoft.web.services3>
    <messaging>
      <mtom serverMode="Always"/>
    </messaging>
  </microsoft.web.services3>  

服务器端主要代码为

[WebMethod]
         public   void  AppendChunk( string  FileName,  byte [] buffer,  long  Offset)
         {
            string FilePath = Path.Combine(_uploadPath, FileName);
            if (Offset == 0)
            {
                File.Create(FilePath).Close();
            }
            using (FileStream fs = new FileStream(FilePath, FileMode.Open, FileAccess.ReadWrite, FileShare.Read))
            {
                fs.Seek(Offset, SeekOrigin.Begin);
                fs.Write(buffer, 0, buffer.Length);
            }
        }

客户段使用backgroudworker上传文件

protected   override   void  OnDoWork(DoWorkEventArgs e)
         {
            try
            {
                long webConfigSetting = this.WebService.GetMaxRequestLength();
                this.MaxRequestLength = Math.Max(1, (webConfigSetting * 1024) - (2 * 1024));
            }
            catch
            {
                this.MaxRequestLength = 4000;
            }
            base.OnDoWork(e);

            this.Offset = Int64.Parse(e.Argument.ToString());
            int numIterations = 0;
            this.LocalFileName = Path.GetFileName(this.LocalFilePath);
            if (this.AutoSetChunkSize)
                this.ChunkSize = 16 * 1024;

            if (!File.Exists(LocalFilePath))
                throw new Exception(String.Format("找不到文件{0}", LocalFilePath));

            long FileSize = new FileInfo(LocalFilePath).Length;
            string FileSizeDescription = CalcFileSize(FileSize);
            byte[] Buffer = new byte[ChunkSize];

            using (FileStream fs = new FileStream(this.LocalFilePath, FileMode.Open, FileAccess.Read))
            {
                fs.Position = this.Offset;
                int BytesRead;
                do
                {
                    BytesRead = fs.Read(Buffer, 0, ChunkSize);

                    if (BytesRead != Buffer.Length)
                    {
                        this.ChunkSize = BytesRead;
                        byte[] TrimmedBuffer = new byte[BytesRead];
                        Array.Copy(Buffer, TrimmedBuffer, BytesRead);
                        Buffer = TrimmedBuffer;
                    }
                    if (Buffer.Length == 0)
                        break;
                    try
                    {
                        this.WebService.AppendChunk(this.LocalFileName, Buffer, this.Offset);

                        if (this.AutoSetChunkSize)
                        {
                            int currentIntervalMod = numIterations % this.ChunkSizeSampleInterval;
                            if (currentIntervalMod == 0)
                                this.StartTime = DateTime.Now;
                            else if (currentIntervalMod == 1)
                            {
                                this.CalcAndSetChunkSize();
                                Buffer = new byte[this.ChunkSize];
                            }
                        }
                        this.Offset += BytesRead;
                        string SummaryText = String.Format("传输 {0} / {1}", CalcFileSize(this.Offset), FileSizeDescription);
                        this.ReportProgress((int)(((decimal)Offset / (decimal)FileSize) * 100), SummaryText);
                    }
                    catch (Exception ex)
                    {
                        Debug.WriteLine("Exception: " + ex.ToString());

                        fs.Position -= BytesRead;

                        if (NumRetries++ >= MaxRetries)
                        {
                            fs.Close();
                            throw new Exception(String.Format("上传文件失败！ \n{0}", ex.ToString()));
                        }
                    }
                    numIterations++;
                } while (BytesRead > 0 && !this.CancellationPending);
            }
        }

发送邮件的代码为：

System.Net.Mail.MailMessage mailMessage  =   new  System.Net.Mail.MailMessage();

                 if  ( string .IsNullOrEmpty(from))
                 {
                    from = ConfigurationManager.AppSettings["FailEmail"];
                }

                mailMessage.From  =   new  System.Net.Mail.MailAddress(from);

                mailMessage.To.Add(to);

                 if  ( ! string .IsNullOrEmpty(bcc))
                 {
                    mailMessage.Bcc.Add(bcc);
                }

                mailMessage.Subject  =  subject;

                mailMessage.IsBodyHtml  =  isBodyHtml;

                 // 附件
                 if  (attach  !=   null )
                 {
                    string directory = GetDirectory();
                    string filePath = string.Empty;
                    string cid = string.Empty;
                    System.Net.Mail.Attachment attachment = null;
                    int i = 0;
                    foreach (string path in attach)
                    {
                        if (!string.IsNullOrEmpty(path))
                        {
                            filePath = Path.Combine(directory, Path.GetFileName(path));
                            MemoryStream ms = new MemoryStream(File.ReadAllBytes(filePath));
                            attachment = new System.Net.Mail.Attachment(ms, Path.GetFileName(filePath));
                            if (content.Contains(path))
                            {
                                cid = String.Format("image_{0}", i);
                                attachment.ContentId = cid;
                                attachment.Name = Path.GetFileNameWithoutExtension(path);
                                content = content.Replace(path, String.Format("cid:{0}", cid));
                                i++;
                            }
                            mailMessage.Attachments.Add(attachment);
                        }
                    }
                }

                mailMessage.Body  =  content;

                SmtpClient.Send(mailMessage);

其中参考了CodeProject上的很多代码，不过不知道具体的地址了，而且懒得去找了。
关于自动发邮件参考了community server 的Job模块（具体实现参考代码，做的很简陋）
先附上代码 /Files/believe3301/Code.rar
第三方程序集 /Files/believe3301/Libs.rar，其中用到了DevExpress的Dll文件太大了所以就不上传了，出现编译错误请下载wse3.0和安装dev
