易采站长站为您分析C#文件断点续传实现方法,涉及C#文件传输的技巧,具有一定参考借鉴价值,需要的朋友可以参考下
本文实例讲述了C#文件断点续传实现方法。。具体实现方法如下：
- /// <summary> /// 下载局域网文件
- /// </summary> /// <param name="path">文件路径，如：192.168.10.1appapp123.zip</param>
- /// <param name="username">计算机名称</param> /// <param name="password">计算机密码</param>
- static void RequestWindowsShared(string path, string username, string password) {
- //文件总大小 int allBytesCount = 0;
- //每次传输大小 int byteTemp = 1024;
- //当前位置 int bytePosition = 0;
- //剩下大小 int remain = 0;
- System.Net.FileWebRequest request = null; System.Net.FileWebResponse response = null;
- System.IO.Stream stream = null; System.IO.FileStream fileStream = null;
- try {
- Uri uri = new Uri(path); request = (System.Net.FileWebRequest)System.Net.FileWebRequest.Create(uri);
- System.Net.ICredentials ic = new System.Net.NetworkCredential(username, password); request.Credentials = ic;
- response = (System.Net.FileWebResponse)request.GetResponse(); stream = response.GetResponseStream();
- byte[] bytes = new byte[stream.Length]; stream.Read(bytes, 0, bytes.Length);
- string filename = System.Environment.GetFolderPath(Environment.SpecialFolder.Desktop) + "" + System.IO.Path.GetFileName(path); fileStream = new FileStream(filename, System.IO.FileMode.Create, System.IO.FileAccess.Write, System.IO.FileShare.ReadWrite);
- allBytesCount = bytes.Length; remain = allBytesCount;
- while (remain > 0) {
- fileStream.Write(bytes, bytePosition, byteTemp); remain = remain - byteTemp;
- bytePosition = bytePosition + byteTemp; fileStream.Flush();
