亲爱的，



我有一个来自数字角色的指纹识别器，我想在使用C＃的Web应用程序中使用它。如何建立连接以从我的计算机上查看设备？



这里是一个示例项目，但它是一个桌面应用程序，所以我怎么能把它作为web申请？

< blockquote>你不会在ASP.NET应用程序中使用它。反正不容易。



ASP.NET代码完全在服务器端运行，所以除非你打算只将指纹识别器连接到服务器，否则...



默认情况下，客户端文件系统和硬件不受浏览器中运行的代码的限制。至少可以说，使用指纹识别器将是一项重大挑战。这将要求客户端安装组件以便使用阅读器，然后您需要在网页中运行代码来处理与阅读器的交互，然后您必须将指纹识别器获得的任何数据发送到单独的在服务器上运行的组件，例如服务，用来做你需要的任何数据。

我有完全相同的问题。

我的解决方案是创建一个本地工作的Http服务器，从浏览器我向服务器发出请求，然后打开一个winforms窗口，其中

解决方案

The reference manual is a good place to start:
DigitalPersona Developer Reference Material[^]

The developer support web pages may have information that could help you:
Developer Technical Support [^] and DigitalPersona Developer WebPortal[^]

You're not going to use it in an ASP.NET app. Not easily anyway.

ASP.NET code runs entirely server-side, so unless you intend to connect the fingerprint reader to the server only, ...

By default, the client filesystem and hardware is off-limits to code running in a browser. Getting at the fingerprint reader will be a major challenge to say the least. This will require the client install a component in order to use the reader, then you'll need code running in the web page to handle the interaction with the reader, then you'll have to send whatever data the fingerprint reader gets to a seperate component running on the server, such as a service, to do whatever you need to with the data.

I had exactly the same problem.
My solution was to create an Http server that works locally, from the browser I make a request to the server which in turn opens a winforms window, in which
The event model of the fingerprint reader Persona Digital is implemented.
