正如@Tim Schmelter所提到的那样，由于您无法通过网络方法访问页面的控件，因此无法回答此问题.

As mentioned by @Tim Schmelter This doesn't answer this question because you can't access page's controls from a webmethod.

请通过 asp.net从静态函数访问控件

[WebMethod]的要点是它们不运行ASP.Net页面生命周期.这样，它们是快速且可并行化的. 您的控件不存在.

The whole point of [WebMethod]s is that they don't run the ASP.Net page lifecycle. This way, they're fast and parallelizable. Your controls don't exist.
