How do I change the July value? I need this to be 100% automated and change it to January. I made a lot of accounts on various websites and need to change them all back to the same birthdate. Yes, I'm aware I'll have to find the ID of it, etc.

推荐答案

查看网站的 HTML 并识别下拉列表的 id 和 values，例如:

View the HTML of the website and identify the id and values of the dropdownlist, for example:

<select id="bdayMonthId" size="1" name="bdayMonth">
    <option value="">Month</>
    <option value="Jan">January</>
    <option value="Feb">February</>
    <option value="Mar">March</>
</select>

要在 WebBrowser 控件中预先选择下拉列表值，请使用此 Winform 代码:​​

To pre-select the dropdownlist value in the WebBrowser control use this Winform code:

webBrowser1.Document.GetElementById("bdayMonthId").SetAttribute("value", "Feb");
