_ = WriteItems（channel.Writer，count，delay）;中的下划线是什么意思？

Question

我正在阅读有关SignalR的信息，并且找到了代码：

  public ChannelReader<int> Counter(int count, int delay)
{
    var channel = Channel.CreateUnbounded<int>();

    // We don't want to await WriteItems, otherwise we'd end up waiting 
    // for all the items to be written before returning the channel back to
    // the client.
    _ = WriteItems(channel.Writer, count, delay);

    return channel.Reader;
}

下划线是什么意思？它是可变的吗？

Answer 1

我可能是错的，但对我来说好像是discard。
