C# 调用调用Delphi dll 实例代码实例代码
介绍了C# 调用Delphi dll 实例代码，有需要的朋友可以参考一下
delphi dll 源码:
复制代码 代码如下:
library dllres;
type
char10 = array[0..9] of char;
TMydata = packed record
id: Integer;
name: char10;
married: Boolean;
salary: Double;
end;
PMydata = ^TMydata;
const
RESSTR: array[0..4] of string = ('HELLO', 'COLOR', 'DELPHI', 'shared', 'library');
NO_RESULT= 'no result';
var
mydata: TMydata;
{$R *.res}
// 返回字符串指针
function getResStr(aindex: Integer): PChar; stdcall;
begin
if aindex < Length(RESSTR) then
begin
Result := pchar(RESSTR[aindex]);
end
else
begin
Result := pchar(NO_RESULT);
end;
end;
// 返回结构体指针
function getMydata: PMydata; stdcall;
begin
with mydata do
begin
id := 123;
name := 'obama';
married := false;
salary := 1200;
end;
Result := @mydata;
end;
exports getResStr, getMydata;
begin
end.
C# 调用示例:
复制代码 代码如下:
class Invoke_Delphi_Dll_Exam
{
[DllImport("dllres.dll", CallingConvention = CallingConvention.StdCall)]
public static extern IntPtr getResStr(int index);
[DllImport("dllres.dll", CallingConvention = CallingConvention.StdCall)]
