我有以下代码下载视频内容：
WebRequest wreq = (HttpWebRequest)WebRequest.Create(url);
using (HttpWebResponse wresp = (HttpWebResponse)wreq.GetResponse())
using (Stream mystream = wresp.GetResponseStream())
{
using (BinaryReader reader = new BinaryReader(mystream))
{
int length = Convert.ToInt32(wresp.ContentLength);
byte[] buffer = new byte[length];
buffer = reader.ReadBytes(length);
Response.Clear();
Response.Buffer = false;
Response.ContentType = "video/mp4";
//Response.BinaryWrite(buffer);
Response.OutputStream.Write(buffer,buffer.Length);
Response.End();
}
}
但问题是整个文件在播放之前下载.如何让它流式传输和播放,因为它仍在下载？还是由客户/接收者应用来管理？
解决方法
您正在将整个文件读入单个缓冲区,然后一次发送整个字节数组.
您应该在while循环中读入较小的缓冲区.
例如：
byte[] buffer = new byte[4096];
while(true) {
int bytesRead = myStream.Read(buffer,buffer.Length);
if (bytesRead == 0) break;
Response.OutputStream.Write(buffer,bytesRead);
}
