PipeTcpNetReceiveAsync 方法

从管道里，接收指定长度的报文数据信息，如果长度指定为-1，表示接收不超过2048字节的动态长度。另外可以指定超时时间，进度报告等
Receives the packet data of a specified length from the pipe. If the length is set to -1, it indicates that the dynamic length of the packet is not more than 2048 bytes. You can also specify timeouts, progress reports, etc

接收固定长度的字节数组，允许指定超时时间，默认为60秒，当length大于0时，接收固定长度的数据内容，当length小于0时，buffer长度的缓存数据
Receiving a fixed-length byte array, allowing a specified timeout time. The default is 60 seconds. When length is greater than 0, fixed-length data content is received. When length is less than 0, random data information of a length not greater than 2048 is received.
