解决方案
解决方案二：
就是把上面代码用vb或是c#解释一下？主要是指针这一块。
解决方案三：
比如像这个FunctionEncodeInit(Parameter:Pointer):SmallInt;stdcall;external'HotelLock.dll';在.net里定义时该用什么类型.
解决方案四：
[DllImport("HotelLock.dll",CallingConvention=CallingConvention.StdCall)]publicstaticexternshortEncodeInit(IntPtrpointer)
解决方案五：
delphi的这种定方法怎样转为C#Parameter:array[0..255]ofchar;
解决方案六：
procedureTAPI_Demo.EncodeInit_BtClick(Sender:TObject);varParameter:array[0..255]ofchar;FunRet:smallint;beginLStrcpy(Parameter,Pchar(LockPath_Ed.Text));FunRet:=EncodeInit(@Parameter);ifFunRet<>1thenbeginMakeCardMsgBox(FunRet);exit;end;这个怎么转为C#LStrcpy(Parameter,Pchar(LockPath_Ed.Text));
解决方案七：
大家帮帮忙啊。
