怎样将INI文件中的以下数据取出,我用的是SPCOM通讯, 写入的是端口参数:想取出来, <br>[Config]<br>ComPort=COM1<br>BaudRate=1200<br>Byte=_7<br>Parity=ODD<br>StopBit=_1<br><br>后面三个在取的时候报错,因为类型不对 ,,请教了

按ReadString读出来再自己处理<br>这样应该可以，就是麻烦点

用TIniFile类，读取ini文件<br>var <br> &nbsp;f:TIniFile;<br>begin<br> &nbsp;f := TIniFile.create('文件名');<br> &nbsp;f.ReadString('Config','ComPort','com1');<br>....

用TIniFile(要uses Inifiles啊),后面三个参数就用楼上的哥们告诉你的字符串,然后你自己判断处理转换就可以了,别告诉我你也不知道如何处理啊.

用readstring和readinteger都不行的,所以才问, &nbsp; 类型不匹配.

Byte=_7<br>有个下划线,你读出后把_去掉再转换成INT不就成了?<br>FByte := Round(copy(ReadString('Config', 'Byte', ''),2,2));

你为什么不去看一下，CNPACK的源码包中有一个根据SPCOMM来写的CRC232,其中就包括了将串口的设置全存入INI文件中的属性了。

还马上给分呢？多不诚实啊！类型不对就用字符串啊，不行再转换吗！

不需要 TIniFile 的，直接使用 GetPrivateProfileString API 就可以了！
