有一段代码是用Delphi写的，实现调用一个C++的dll的函数。
我现在需要按着Delphi的写法改秤C#来调用。
现在改完了以后有些问题。（程序执行，dll调用都正常，对int的赋值也正确，只是对结构体的赋值就不正确，不报错，但值不正确。）
请看代码：
/**************************************Delphi代码**************************************/
varRecords:LabelPLU;
begin
Records.PLUNo:=1;
Records.EAN_Data.ItemCode:='1234500000';
Records.EAN_Data.BarCodeType:=0;
Records.EAN_Data.BarRightData:=0;
Records.Commodity[0].TwsFontSize:=21;
Records.Commodity[0].TxtValue:='商品名称test';
CommResult:=SendLPlu(s,@Records);
end;
/*****************

*****************/
functionSendLPlu(s:TSocket;PLUData:PLabelPLU):Integer;stdcall;external'×××.dll';
/**************

LabelPLU=record
PLUNo:Integer;
EAN_Data:SM_EANData;
Commodity:array[0..3]ofSM_ASCII_TXT;
end;
PLabelPLU=^LabelPLU;
/*************

*************/
SM_EANData=record
ItemCode:array[0..9]ofchar;
BarCodeType:Integer;
BarRightData:Integer;
end;
/*************

SM_ASCII_TXT=record
TwsFontSize:Integer;//字体
TxtValue:array[0..99]ofchar;//文本内容
end;
/****************************************C#翻译的代码部分****************************/

（ps:经测试，发现红色部分代码没生效。）
请大侠帮忙分析分析原因呢？谢谢各位先！
