使用GetPrivateProfileString出现错误

[sfw2fly]

var
Jilu1:array[1..100] of char;
//Jilu1:string;
begin
//setlength(Jilu1,100);
If OpenDialog1.Execute then
Logfilename:=Opendialog1.filename;
GetPrivateProfileString('123','abc','',@Jilu1,100,LogfileName);//问题出现行
labeledEdit1.Text:=Jilu1;
end;

==========================================
我使用这段代码时，报告错误“Incompatible types: 'String' and 'PAnsiChar'.哪位知道怎样解决，请告知小弟。
