如何向DLL传递动态数组?(100分)

type<br>&nbsp; TFieldInfo=packed record<br>&nbsp; &nbsp; FieldName:Array[0..50] of char;<br>&nbsp; &nbsp; FieldCaption:Array[0..50] of Char;<br>&nbsp; &nbsp; FieldDataType:TFieldType;<br>end;<br><br>Var<br>&nbsp; FI:Array of TFieldInfo<br>在主程序向FI赋值后,如何从主程序向DLL传递动态数组FI?

指针就可以

能具体点吗?如何传递,DLL中如何转换?

看看老帖子 http://www.delphibbs.com/delphibbs/dispq.asp?lid=602645 吧——很详细。

看贴子就也行了....<br>就是定义个R_TFieldInfo=Array of TFieldInfo<br>然后把这个传进去<br>当然如果你在里面如果没有用到Setlength这些的话.<br>用var Fi:array of TFieldInfo也是可以的..

不要这样传递.传FI的第一个元素地址,和参数Count.<br>type<br>&nbsp; PFieldInfo = ^FieldInfo;<br>&nbsp; TFieldInfo=packed record<br>&nbsp; &nbsp; FieldName:Array[0..50] of char;<br>&nbsp; &nbsp; FieldCaption:Array[0..50] of Char;<br>&nbsp; &nbsp; FieldDataType:TFieldType;<br>end;<br><br>Var<br>&nbsp; FI:Array of TFieldInfo<br>DLL函数接口.<br>procedure XXX(pfi: PFieldInfo ; Count : Integer);<br>调用方式<br>XXX(@FI[0], Length(FI));
