如何使用C＃将生物制作设备连接到ASP.NET中的Web应用程序 [英] How to connect biomatric device to web application in ASP.NET with C#

问题描述

我想将生物制作设备同步到网络应用程序......并通过webservice从生物制作设备读取数据，以及.dll文件用于读取生物制作设备数据..



我尝试了什么：



我没试试..但我需要建议plz帮助我..我需要知道整个过程..how biomatric设备连接和如何验证..如何使用webservice读取数据并在Web应用程序中使用

解决方案

当我们怎样才有人可能回答这个问题不知道你正在使用什么设备，它有什么API，它支持什么等等？无论你多少次问这个问题，你都不会得到有意义的答复。我唯一要说的是，使用asp.net很可能无法做到这一点（正如您之前所说），服务器无法访问连接到客户端计算机的设备。 / blockquote>

原则上，webapps无法访问客户端文件系统或客户端硬件。

这是防范恶意软件的基本安全性。

我需要知道整个过程

简答：整个过程是' Niet'。

您无法使用Web应用程序直接连接/与客户端计算机硬件通信。但是您可以尝试以下方法：使用ActiveX组件或创建Windows服务（WCF，WebAPI等）。



它的通信类似于：Web应用程序< - - > Windows服务< ---->硬件

解决方案

How can anyone possibly answer this question when we have no idea what "device" you are using, what API it has, what it supports and so on? It doesn't matter how many times you ask this question you are not going to get a meaningful reply. The only thing I'll say is that it is highly likely it won't be possible to do this using asp.net as (as you've been told before) the server can't access devices attached to the client machine.

By principle, webapps don't have access to client file system or client hardware.
That is basic security to protect from malware.

i need to know whole process

Short answer: The whole process is 'Niet'.

You cannot directly connect/communication with the client machine hardware using web application. But here's some approach you can try: Use ActiveX component or Create a Windows Service(WCF, WebAPI etc..).

It communication like: Web Application <---> Windows Service <---->Hardware
