Asp.net 如何在Kentico自定义BizForm中上载多个文件？ 我有一个表单创建为ascx控件。数据已成功保存在biz表单中。我的问题是如何上传文件？我不知道上传文件时使用的控件是否正确？以及如何在此处添加文件upload submit rec.SetValueUploadCV、duUploadCV.InnerAttachmentGUID；你们可以看到下面的点击按钮代码。我在下面有代码ascx和.cs。我使用的ascx上传控件是否正确？设计代码如下。代码.cs是

我认为您需要触发直接上传程序以某种方式保存文件，然后它才会给您一个GUID-我不完全熟悉它的工作原理，因为我从未在Kentico表单引擎的上下文之外使用过它

话虽如此，我认为Kentico中的表单模块可以完成我所看到的您在这里尝试完成的所有操作，而无需编写自定义代码

每当我在Kentico中创建表单时，我都会尽量利用表单模块

我建议您通读Kentico的任何版本的表单模块文档，尝试通过用户界面创建表单，然后在过程中遇到问题时询问问题，除非有我误解的自定义内容
