我正在使用HTTP Web请求，响应从jenkins服务器获取url响应。读取响应并使用Filestream将其存储在本地驱动器中。当响应是连续的，我可以成功下载并安装exe文件。文件大小下载大于400MB如何避免/跳过HTTP响应中的异常，在c＃中的文件下载期间添加为字节
问题场景：虽然读取有时会发生超时，但会引发异常。响应阅读器也读取该异常并存储在文件中。
例外：

如何避免读取例外字节，这样我可以对剩余的字节再继续下载。
这里是我的逻辑：
try
{
long iFileSize = 0;
int iBufferSize = 1024;
iBufferSize *= 1000;
long iExistLen = 0;
if (System.IO.File.Exists(path))
{
System.IO.FileInfo fINfo =
new System.IO.FileInfo(path);
iExistLen = fINfo.Length;
}
if (iExistLen > 0)
saveFileStream = new System.IO.FileStream(path,
System.IO.FileMode.Append, System.IO.FileAccess.Write,
System.IO.FileShare.None);
else
saveFileStream = new System.IO.FileStream(path,
System.IO.FileMode.Create, System.IO.FileAccess.Write,
System.IO.FileShare.None);
HttpWebRequest hwRq1 =(HttpWebRequest)System.Net.HttpWebRequest.Create(urlAddress);
hwRq1.AddRange((int)iExistLen);
using (HttpWebResponse hwRes=(System.Net.HttpWebResponse)hwRq1.GetResponse())
{
using (System.IO.Stream smRespStream = hwRes.GetResponseStream())
{
smRespStream.ReadTimeout = 60000;
iFileSize = hwRes.ContentLength;
int iByteSize;
byte[] downBuffer = new byte[iBufferSize];
while ((iByteSize = smRespStream.Read(downBuffer, 0, downBuffer.Length)) > 0)
{
saveFileStream.Write(downBuffer, 0, iByteSize);
Console.WriteLine(iExistLen.ToString());
}
saveFileStream.Close();
smRespStream.Close();
if (iByteSize == 0 && !FileSizeCheck(path, softwareWithSize.Value))
return new Tuple<string, bool>("Zero byte received", false);
}
}
感谢您的回复，我使用原始文件和错误文件之间的二进制比较器来获取异常 – guru
我没有编程方式来检测发生错误，您需要检查每个文件的末尾下载以查找ascii错误文本并将其删除 –
