我在使用C#调用Delphi 7 DLL文件时遇到问题.我是C#的新手,对Delphi知之甚少,我不需要真正了解那么多.我只需要尽快解决这个问题.

我试图从C#调用DLL但我得到这个错误:"尝试读取或写入受保护的内存.这通常表明其他内存已损坏."

我不知道为什么会这样.正如您将在我的Delphi代码中看到的那样,我不会尝试返回任何值.我只需要在COM端口上发送一些命令.如果有人可以帮助我离开这里:(

Delphi DLL代码:

library Project2;


uses
  SysUtils,
  ComPort,
  Classes;

var com1:TComport ;

{$R *.res}
procedure moveforward; export;
begin
  com1.WriteAnsiString('#20 P1528 CR'+sLineBreak);
  com1.WriteAnsiString('#7 P1465 CR'+sLineBreak);
end;

procedure movebackward; export;
begin
  comport1.WriteAnsiString('#7 P1528 CR'+sLineBreak);
  comport1.WriteAnsiString('#20 P1465 CR'+sLineBreak);
end;

procedure stopmove;export;
begin
  comport1.WriteAnsiString('#20 P1500 CR'+sLineBreak);
  comport1.WriteAnsiString('#7 P1500 CR'+sLineBreak);
end;

procedure catch; export;
begin
  comport1.WriteAnsiString('#2 P2120 T2000 CR'+sLineBreak); //arm
  comport1.WriteAnsiString('#30 P2260 T500 CR'+sLineBreak); //gripper
end;

procedure initialize; export;
begin
  comport1.WriteAnsiString('#2 P2184 T1000 CR'+sLineBreak); //arm
  comport1.WriteAnsiString('#30 P1980 T2000 CR'+sLineBreak); //gripper
end; …
