来自asp.net的串口访问 [英] serial port access from asp.net

问题描述

我需要从asp.net页面访问我的网络服务器上的串口。我没有问题从windows窗体应用程序访问串口，没问题，

但代码在asp.net中不起作用。我被告知无法从$ asp访问来自asp.net的串口。


该应用程序用于控制自定义硬件。硬件是通过串口连接到PC的
。我们的客户希望从远程位置控制

硬件，因此我们的想法是在PC上运行IIS

并通过网页控制记录器。

解决方案

我会考虑用Windows服务控制设备的解决方案

和ASP.NET应用程序通过windows服务通过一个常见的

持久性数据存储，例如文件。

没有托管API连接到v1.x中的串行端口。但是在v2.0中有

。如果你现在需要一个解决方案，你必须编写非托管的

代码，然后互操作才能访问它。

I need to access the serial ports on my webserver from an asp.net page. I
have no problem accessing the serial ports from a windows form application,
but the code doesn''t work in asp.net. I have been told it is not possible to
access the serial ports from asp.net.

The application is used to control custom hardware. The hardware is
connected to a PC through serial ports. Our customer wants to control the
hardware from a remote location so our idea was to have IIS running on the PC
and the recorder controlled through a web page.

解决方案

I would consider a solution with a windows service controlling the device
and an ASP.NET application talking to the windows service via a common
persistent data storage, such as a file.

There are no managed APIs to connect to the serial port in v1.x. There are
in v2.0 though. If you need a solution now, you''ll have to write unmanaged
code and then interop to access it.

Here is a .net assembly for accessing the serial port:
