求助!我是菜鸟!
各位高手,帮帮忙,我刚开始学C#,现在实习,老总叫我用C#编个实现串口通信的程序,后来在网上搜了下,下了源代码,(我装的是VS 2005) 把那程序复制进去,可是,报错说:缺少partial关键字,后来我添加了它,又出现更多问题了,报错说:某些变量重复定义了,后来我把把form.cs中的这些定义删了。最后出现了三个问题:都是在progam.cs中的:1、找不到类型或命名空间名称“Form1”(是否缺少using指令或程序集引用?) ;
2、与“System.Windows.Forms.Application.Run(System.Windows.Forms.Form)”最匹配的重载方法有一些无效参数;
3、参数 '1',无法从'Form1'转换为“System.Windows.Forms.Form"
等下我把我下的源代码传上来,希望高手指导我下,并发到我邮箱里:hongcaifudyx@
另外教些学C#的方法和注意事项,谢谢啊!

刚实习,就用C#编个实现串口通信的程序...
强......
我也刚学不久,很想知道这个是怎么写出来的
楼主搞定之后,发我一份看看吧 dingpin1986521@
谢谢了......

我的地盘我做主!

别用vs打开,用第三方工具修改。vs2005向下兼容不是很好。不过我看你还是找人做交差吧。

这个根本就不是向下兼容的问题,LS的,你注意看楼主,他是直接把别人代码粘过来……明显的就是重复定义,然后在改的时候又把人家的一些定义给删掉了。其实拿到别人的代码最好还是先看,理解,最后自己动手写。直接COPY………………

楼上说的对...
看来楼主不是一般的菜鸟啊...
这个跟VS还是DOS无关的...
明显的是代码没COPY完全(或正确)....

这问题已经解决了,谢谢你们啊!
上面问题已经解决了,可是又出现了新的问题:串口初始化失败!这个要怎么解决啊?另外,有谁知道,编写mycom类时怎么把串口通信协议联系起来啊?可不可以给我详细讲解下编写这个类的过程和方法?谢谢拉!
