Question

我是DELPHI的初学者，我有一个问题.. 如何调用此函数并使用它，我想在标签中显示结果，以及如何以正确的方式声明函数，非常感谢提前。

function FindFileSize(Filename:string):integer;
var
sr : TSearchRec;
begin
if FindFirst(filename,faAnyFile-faDirectory,sr) = 0 then
Result := sr.Size
else
raise EFileNotFoundException.Create(filename+' not found.');
FindClose(sr);
end;
