TCP / IP收到数据问题...... [英] TCP/IP received data questions...

问题描述

hi ...

在我的应用程序中，我使用TCP / IP进行通信。我将从以太网上的许多PC获取数据。我正在使用以下代码来获取数据。

  In my application i am communication using TCP/IP. I will get data from many PCs on ethernet. I am using following code to get the data.

我对此有几个问题...

 I have few questions on this...

如果数据我如何识别数据收到的是哪个IP地址。我可以在Socket对象中获取该信息吗？？我在发送数据后调用'BeginReceive'...如果我必须在不发送任何数据的情况下获取接收数据，该怎么办...？
如果我要接收大数据，我不知道我将在以太网端口上收到的数据的大小...在这种情况下应该是'size'的值...？

how i can identify the data if the data received is from which IP address. Can i get that information in Socket object...?
I am calling 'BeginReceive' after sending data... What i should do if i have to get receive data without sending any data...?
In case i am going to receiv large data, I dont know the size of the data which i will receive on ethernet port... in that case what should be value of 'size'...?

谢谢，我IamHuM
