[请教]blob类型能用variant表示吗？谢谢

Answer 1

stream不能给variant啊！
请教了
var
v:variant;
TmpMemStream:TMemoryStream;
s:string;
i:integer;
begin
s:='aaa';
i:=1;
v:=s;
v:=i;
  TmpMemStream:=TmemoryStream.Create;
  TmpMemStream.LoadFromFile('c:\22.txt');
  TmpMemStream.Position:=0;
v:=variant(TmpMemStream);

Answer 2

var
v:variant;
TmpMemStream:TMemoryStream;
s:string;
i:integer;
begin
s:='aaa';
i:=1;
v:=s;
v:=i;
  TmpMemStream:=TmemoryStream.Create;
  TmpMemStream.LoadFromFile('c:\22.txt');
  TmpMemStream.Position:=0;
v:=variant(TmpMemStream);
这样是要报错的..
