【问题】
一个C#编译出来的exe程序，该exe是单独的exe，无额外的配置文件等东西。
exe放到一个Win7下的共享盘里面，然后在另外一台电脑上，访问该exe，直接运行，出错：
Error creating the Web Proxy specified in the ‘system.new/defaultProxy’ configuration section
错误截图：
错误log：
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
现在想要找到出错的根本原因。
【解决过程】
1.后来经过验证，当把此exe，从（网上邻居中的）共享盘，拷贝到当前硬盘中，再运行就正常了，就没了错误了。
2.后来又经过测试，直接通过我本机的win7下，访问该网盘上的该exe，直接运行该exe，则是正常的，也不会出现这个错误。
3.但是还是想要去多了解此错误，想要搞懂为何会出现此错误。
4. 网上这人：
error creating the web proxy specified in the ‘system.net/defaultproxy’ configuration section
遇到和我类似的情况，也是网络上运行程序出错，本地运行是正常的。
5.这里：
Error creating the web proxy specified in the ‘system.net/defaultproxy’ configuration section
是通过“netsh winsock reset”然后重启解决问题的。
【总结】
懒得继续找根据原因了。总之是：
将exe从网络共享中，拷贝到本地，就是可以正常运行的了。
