无法打开端口COM2：System.Security.Permissions.SecurityPermission [英] Unable to open port COM2: System.Security.Permissions.SecurityPermission

问题描述

我使用GSM通信和PDU转换器DLL文件在我的asp.net网站上发送短信。我的localhost一切都很好。我可以轻松地在本地主机上将短信PC发送到手机。



但是有问题。我无法从我的网站（托管）发送短信。当我想发送短信时，它显示错误：



GsmComm.GsmCommunication.CommException：无法打开端口COM2：

系统。 Security.Permissions.SecurityPermission ---> System.Security.SecurityException：GsmComm.GsmCommunication.SerialPortFixer..ctor（String portName）中的System.Security.Permissions.SecurityPermission，位于GsmComm的GsmComm.GsmCommunication.SerialPortFixer.Execute（String portName） GsmComm.GsmPhone.OpenPort（String portName，Int32 baudRate，Int32 timeout）在GsmComm.GsmCommunication.GsmPhone.Open（）---内部异常堆栈跟踪结束---在GsmComm的GsmComm.GsmCommunication.GsmPhone.Open（）处.GsmCommunication.GsmCommMain.Open（）at BRUR.examiner.smsExaminer.testSendingSms（）



可能需要访问端口的权限。但是我怎么能这样做呢？请立即帮助我。我今天需要在我的univarsity上提交我的网站。

Hi, I used GSM Communication and PDU Converter dll file to send sms in my asp.net website. Everything is fine in my localhost. I can easily send sms PC to Mobile in my localhost.

But there is a problem. I couldn't send sms form my website(hosted). When I want to send sms, it shows error:

" GsmComm.GsmCommunication.CommException: Unable to open port COM2:
System.Security.Permissions.SecurityPermission ---> System.Security.SecurityException: System.Security.Permissions.SecurityPermission at GsmComm.GsmCommunication.SerialPortFixer..ctor(String portName) at GsmComm.GsmCommunication.SerialPortFixer.Execute(String portName) at GsmComm.GsmCommunication.GsmPhone.OpenPort(String portName, Int32 baudRate, Int32 timeout) at GsmComm.GsmCommunication.GsmPhone.Open() --- End of inner exception stack trace --- at GsmComm.GsmCommunication.GsmPhone.Open() at GsmComm.GsmCommunication.GsmCommMain.Open() at BRUR.examiner.smsExaminer.testSendingSms()"

May be there is need permission to access port. But how can I do this? Please help me immediate. I need to submit my website today at my univarsity.

推荐答案

托管？主持人是什么？哪里??



我严重怀疑你是否可以访问主机服务器上的COM端口，尤其是第三方主机上的COM端口。

Hosted?? Hosted by what?? Where??

I seriously doubt you're going get access to COM ports on a host server, especially so on 3rd-party hosts.
