很像Server-Client的東西 Host-Client<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

利用剛才說的HOST建立方法建立HOST

稍微修改一下,畢竟不能每次都new一個Guid的.所以以后不出意外都用這個

Guid("358E<?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />1C8D-DB4A-4867-B2C3-DEF3F5046B17")

端口 2603

或許可以做成一個HOST類,呵呵,那樣的話就是結構問題了,有點超出我的計劃.我強調的是實現,至于如何做一個好的結構以后再說.

一開始走了不少彎路,而且有N次沒有響應….

代碼經過再三壓縮,終于控制再100行左右了(自動生成的除外).代碼多了容易讓人誤會的,比如微軟的那個.

HOST一個需要7行.

說一下FindHOST的大體步驟

1 首先自己也是一個Peer啦,所以new一個就可,別的不要

2 appdescription 主要就是那個guid,必須一樣(不一樣我也不知道會怎樣)

3 LocalAddress 本地地址,主要就是設置一下本地端口 比如2555

4 HOSTAddress 服務器地址,主要是協議,當然,多一些信息也可,具體看代碼

5 添加一個事件,MS用的是addhandler 我個人習慣用 withevents(個人VB6的遺留問題..)用于響應HOST的回復

6 Peer.FindHOST(@#$%^$%^&*(&…..) 然后就等著信息吧.本來很簡單的事情被弄得復雜了.整理完了之后發現真的很簡單.具體的就不多說了,100行不到,自己看吧

注意1,find的時候最好用none,否則有可能導致假死或者錯誤.或者要求輸入IP..

注意2,HOST的時候,如果你不發送本機,那么本機將會搜索不到,但是別的機器可以
