How to search TStringlist Item in delphi

Sometimes we need to know whether a string is contained in a stringlist. This post will discuss about how to find a string inside the stringlist. If it is found, it will return true, otherwise false. Here is the sample code :

var MyList:TStringlist;
    Found:Boolean;
begin
 if MyList.IndexOf('item name') = -1 then
   Found := false
 else
   Found := true;
end;
