错误 1 “System.Runtime.InteropServices.CallingConvention”并不包含“StdCall”的定义 D:\软件\C#\项目\SMT上料核对PDA\SmtFeedCheck\SmtFeedCheck\FrmMain.cs 62 100 SmtFeedCheck错误 2 “System.Diagnostics.Process”不包含“MainModule”的定义，并且找不到可接受类型为“System.Diagnostics.Process”的第一个参数的扩展方法“MainModule”(是否缺少 using 指令或程序集引用?) D:\软件\C#\项目\SMT上料核对PDA\SmtFeedCheck\SmtFeedCheck\FrmMain.cs 79 73 SmtFeedCheck
我这里的运行环境是 Win CE5.0 + .NET 3.5 的环境

一直解决不了 ，最后用了厂家提供的DLL处理。
