未处理CryptographicException：系统找不到指定的文件 [英] CryptographicException was unhandled: System cannot find the specified file

问题描述

我正在尝试拥抱SSL通信的奥秘，并在此网站。我正在尝试测试自己的证书。使用Visual Studio 2012，我仅添加了一个现有文件（我的证书为.pfx格式），然后在app.config中更改了证书和密码设置。但是，在尝试运行它时，出现错误：

I am trying to embrace the mysteries of SSL communication and have found a great tutorial on this site. I was trying to test my own certificate. Using Visual Studio 2012, I simply added an existing file (my certificate in .pfx format) and then changed the "certificate" and "password" settings in app.config. However, when trying to run it, I got an error:

CryptographicException未处理：系统找不到指定的文件

CryptographicException was unhandled: System cannot find the specified file

然后，我在Web Service中尝试了相同的操作。那里有关于该错误的更多详细信息：

Then, I tried the same in my Web Service. There I got some more details about the error:

System.Security.Cryptography.CryptographicException: System cannot find specified file.

我已经向文章作者写了这个问题，但是由于他的上次答复是在2012年3月，所以我不确定他是否会答复。如果有人可以帮助我解决这个问题，我将不胜感激。

I have written this question to the author of the article, but since his last reply was in March 2012, I am not sure, whether he will reply. If somebody could help me with this problem, I would be very grateful.

PS：将证书从.cer导出到.pfx时，我更改了文件已导出。尽管我怀疑它对问题的影响，但我还是会提及它。

P.S.: When exporting the certificate from .cer to .pfx, I have changed the title of the file exported. Although I doubt its effect on the problem, I'd rather mention it.
