WCF+上传+大文件处理

大文件处理的方式拆分读取，此文只为记录文件处理方式，供日后查阅。

源码来自http://blog.csdn.net/lywust/article/details/7009248

经过改编将源码改编为文件上传的功能如下(处理几个GB的文件应该是没有问题的)

客户端

 public partial class WebForm1 : System.Web.UI.Page

     {

         protected void Page_Load(object sender, EventArgs e)

         {

         }

         protected void Button1_Click(object sender, EventArgs e)

         {

             BigFileRead(@"E:\工具\开发工具\数据库\SqlServer\2008 r2\cn_sql_server_2008_r2_enterprise_x86_x64_ia64_dvd_522233.iso");

             Response.Write("文件传输成功！");

         }

         private void BigFileRead(string strFilePath)

         {

             UploadService c = new UploadService();

             //每次读取的字节数

             int iBufferSize = ;

             byte[] buffer = new byte[iBufferSize];

             FileStream fs = null;

             try

             {

                 fs = new FileStream(strFilePath, FileMode.Open);

                 //文件流的长度

                 long lFileSize = fs.Length;

                 //文件需要读取次数

                 int iTotalCount = (int)Math.Ceiling((double)(lFileSize / iBufferSize));

                 //当前读取次数

                 int iTempCount = ;

                 while (iTempCount < iTotalCount)

                 {

                     //每次从最后读到的位置读取下一个[iBufferSize]的字节数

                     fs.Read(buffer, , iBufferSize);

                     ////将字节转换成字符

                     //string strRead = Encoding.Default.GetString(buffer);

                     ////此处加入你的处理逻辑

                     //Console.Write(strRead);

                     c.UploadFile("aaa.iso",buffer);

                     iTempCount++;

                 }

             }

             catch (Exception ex)

             {

                 //异常处理

             }

             finally

             {

                 if (fs != null)

                 {

                     fs.Dispose();

                 }

             }

         }

     }
