Stream分段写入提示“请求被中止: 请求已被取消”
为了实现一个文件上传的功能，我将上传的文件分段写入Stream类的对象，如果文件过大（貌似大于3M）就会提示“请求被中止: 请求已被取消”，如果不分段的话就能成功上传不提示任何问题。看代码
int UploadNum=0;
Stream dataStream = request.GetRequestStream();
UploadNum = postData.Length / 5000;
System.Threading.Timer FileTm = new System.Threading.Timer(CalculateSpeedTime, null, 0, 1500);
for (int i = 0; i <= UploadNum; i++)
{
if (i == UploadNum)
{
dataStream.Write(postData, i * 5000, postData.Length - i * 5000);
TempDataSize += postData.Length - i * 5000;
}
else
{
dataStream.Write(postData, i * 5000, 5000);//这里会报错
TempDataSize += 5000;
}
setprogressbar(true, (i * 5000.0 / postData.Length) * 100.0, UploadSpeed);
}
dataStream.Close();
