XmlTextReader reader = new XmlTextReader (URLString); 讀取XML。 注意 此步驟顯示基本、外部 while 迴圈,以及接下來兩個步驟說明如何使用該迴圈和讀取 XML。 載入之後, XmlTextReader 執行循序讀取,以跨 XML 數據移動,並使用 Read 方法來取得下一筆記錄。 如果沒有其他記錄,此方法 Read 會傳回 false。
如果你希望确定是否可以从标准输入和某个socket描述符读取数据,你只需要将标准输入的文件描述符0和相应的sockdtfd加入到readfds集合中;numfds的值 是需要检查的号码最高的文件描述符加1,这个例子中numfds的值应为sockfd+1;当select返回时,readfds将被修改,指示某个文件 描述符已经准备被读取,你可以通过FD_ISSSET...
