C# 如何使用HtmlTextWriter生成表单的OnSubmit属性

我需要的Html将类似于：

<form onsubmit="return manipulateForm()">
...
</form>

---

问题是HtmlTextWriterAttribute枚举没有OnSubmit的定义，我能通过它吗？

刚刚看到HtmlTextWriter类具有AddAttribute的覆盖函数

公共虚拟void AddAttributestring名称、字符串值

因此，解决方案如下所示：

using (HtmlTextWriter writer = new HtmlTextWriter(new System.IO.StringWriter(innerBuffer)))
{
    writer.AddAttribute("onsubmit", "return manipulateForm()");
}

using (HtmlTextWriter writer = new HtmlTextWriter(new System.IO.StringWriter(innerBuffer)))
{
    writer.AddAttribute("onsubmit", "return manipulateForm()");
}
