Delphi对字符串算式进行计算

首先看这里Using Delphis Expressions Engine我自己的测试代码uses System.Bindings.Expression, System.Bindings.Helper; procedure TForm1.Button3Click(Sender: TObject); var Expr: TBindingExpression; begin Expr : TBindings.CreateExpression([], 23); //测试通过。 Expr : TBindings.CreateExpression([], 23); //测试通过返回 false try Log(Expr.Evaluate.GetValue.ToString); finally Expr.Free; end; end;
