Try using the Microsoft Script Control. First add a reference to your project to the Microsoft Script Control 1.0 which can be found under the COM tab. The code to use it will then be on the following lines: protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { var sc = new MSScriptControl.ScriptControl(); sc.Language = "JScript"; Session["ScriptControl"] = sc; } } protected void Button1_Click(object sender, EventArgs e) { var sc = Session["ScriptControl"] as MSScriptControl.ScriptControl; try { TextBox2.Text = sc.Eval(TextBox1.Text).ToString(); } catch { TextBox2.Text = "INVALID FORMULA"; } }
