如何从C#生成的html输入中获取多个值

string html = "<form action='process-form' method='post'>";
html += "<input type='text' name='input1' />";
html += "<input type='text' name='input2' />";
html += "<input type='text' name='input3' />";
html += "<input type='submit' value='Submit' />";
html += "</form>";

// 处理表单提交的页面或方法
public ActionResult ProcessForm(FormCollection form)
{
    string input1Value = form["input1"];
    string input2Value = form["input2"];
    string input3Value = form["input3"];

    // 进一步处理获取到的值
    // ...

    return View();
}
