WCF传输文件的时候可以设置每次文件的传输大小，如果是小文件的时候，可以很方便的将文件传递到服务端，但是如果文件比较大的话，就不可取了
遇到大文件的话可以采取分段传输的方式进行文件传输
思路：
1、客户端循环传递
2、将文件分割成指定大小的字节块
3、每次传输一小块后，客户端将当前文件的读取指针移动到指定位置
4、服务端每次依照传递过来的字节文件追加
问题：假设文件有好几个G大小，按照上述方式进行文件传输，当文件传递到99%的时候突然由于客观原因而造成文件传输失败，直接会造成服务器已经上传的文件不可用，必须重新上传
解决方案：
可以采取断点续传的模式
1、当服务器第一次传输文件的时候，可以先通过服务检查服务器上是否已经存在当前文件，如果存在则返回服务器上文件的最大指针位置，如果不存在则默认为0
2、判断服务器指针最大位置是否大于等于当前文件指针位置；如果大于等于，则文件已经存在
a）大于等于：由于每次上传的文件字节数是固定的，假设传递到最后一块，本地文件小于要求的传递数量，服务端还是按照规定大小的字节数进行写文件
2、客户端拿到服务器上返回的文件指针位置后，循环发送文件开始，将读取文件指针直接移动到服务器返回的文件指针位置
文件传输案例：
1、可以断点续传
2、同时传输多台服务器
3、显示计算当前文件的上传速度
4、传递完成后文件自动解压

三：解压公共方法：
using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace FileServicesBLLContract.Common { public class UnZip { ////// 解压文件 /// /// 压缩包路径 /// 要解压的路径 public static void UnZipFile(string SrcFile, string DstFile) { string[] FileProperties = new string[2]; FileProperties[0] = SrcFile;//待解压的文件 FileProperties[1] = DstFile;//解压后放置的目标目录 UnZipClass UnZc = new UnZipClass(); UnZc.UnZip(FileProperties); } } }
using System; using System.Collections.Generic; using System.Linq; using System.Text; using ICSharpCode.SharpZipLib.Zip; using System.IO; namespace FileServicesBLLContract.Common { public class UnZipClass { public void UnZip(string[] args) { ZipInputStream s = new ZipInputStream(File.OpenRead(args[0])); ZipEntry theEntry; while ((theEntry = s.GetNextEntry()) != null) { string directoryName = Path.GetDirectoryName(args[1]); string fileName = Path.GetFileName(theEntry.Name); //生成解压目录 //Directory.CreateDirectory(directoryName); if (!Directory.Exists(directoryName)) { Directory.CreateDirectory(directoryName); } if (fileName != String.Empty) { string filePath = (args[1] + theEntry.Name).Replace(fileName, ""); if (!Directory.Exists(filePath)) { Directory.CreateDirectory(filePath); } //解压文件到指定的目录 FileStream streamWriter = File.Create((args[1] + theEntry.Name).Replace("'", "")); int size = 2048; byte[] data = new byte[2048]; while (true) { size = s.Read(data, 0, data.Length); if (size > 0) { streamWriter.Write(data, 0, size); } else { break; } } streamWriter.Close(); } } s.Close(); } } }

服务接口
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.ServiceModel; using System.IO; using SynFilesContract.Course; using ELearning.Model.Course; namespace SynFilesContract { // 注意: 如果更改此处的接口名称 "IContract"，也必须更新 App.config 中对 "IContract" 的引用。 [ServiceContract] public interface SynIFileServicesInterface { ////// 上传文件 /// /// 文件对象 /// 上传文件类型 0、照片；1、SCROM文件；2、三分屏文件\ /// 课件编号 /// /// 课程编号 /// [OperationContract] UploadFileInfo UplodaFile(UploadFileInfo file, string Type, string UrlName, string Path); /// /// 上传文件 /// /// 文件名 /// 当前指针 /// 每次上传字节大小 /// 上传文件类型1、SCROM课程 2、ThreadSreen课程 /// 用户Id /// 当前文件上传路径 /// 客户端文件上传路径 /// 客户端文件原始字节长度 /// [OperationContract] bool UploadFile(string FileName, long offSet, byte[] intoBuffer,string FullName, string Path,long FileLength); [OperationContract(AsyncPattern = true)] IAsyncResult BeginUploadFile(string strPath, long offSet, byte[] intoBuffer, string FullName, string Path,long FileLength, AsyncCallback ra, object state); bool EndUploadFile(IAsyncResult ra); /// /// 获取文件当前上传的长度 /// /// 文件名 /// 上传文件类型1、SCROM课程 2、ThreadSreen课程 /// 用户Id /// 当前文件上传路径 /// 长度 [OperationContract] long GetFilesLength(string FileName,string paths); } }
