}
2.
byte[] buffer = new byte[204800];
while (dataToRead > 0)
{
if (HttpContext.Current.Response.IsClientConnected)
{
int length = stream.Read(buffer, 0, Convert.ToInt32(chunkSize));
HttpContext.Current.Response.OutputStream.Write(buffer, 0, length);
HttpContext.Current.Response.Flush();
HttpContext.Current.Response.Clear();
dataToRead -= length;
}
else
{
dataToRead = -1; //防止client失去连接
}
}
这是大文件下载的代码，2个人写的。一个人在stream.Read(buffer, 0, Convert.ToInt32(chunkSize));后写了buffer = new Byte[10000];数组被重新初始化了，一个没有写，在while循环里直接多次使用，到底该不该清空数组呢？请大神们指教！！！
