问题 ScriptManager.RegisterStartupScript(this, this.GetType(), "redirectScript", "window.location.href='Thankyou.aspx?'Service=" + hidService.Value + ";",true); 获取错误:预期; 请帮我 回答1 我觉得你的报价有点乱,试试: ScriptManager.RegisterStartupScript(this, this.GetType(), "redirectScript", "window.location.href='Thankyou.aspx?Service=" + hidService.Value + "';", true); 您在Service=之后有一个单引号,它应该在您的;之前; .
