小编dc.*_*dc.的帖子

我正在使用Visual Studio 2008 Pro创建VB Winform应用程序.我的app.config文件中有一些自定义配置设置以及MS SQL连接字符串.

1. 确保没有人可以在app.config中读取这些设置的最佳方法是什么？
2. 是否有任何其他区域的纯文本连接字符串,我可能也想考虑保护？

谢谢!

我在将字符串转换为我需要的日期格式时遇到问题.我试图转换的字符串的一个例子是215056081909.我想将该字符串转换为08/19/09 21:50:56.

下面列出的代码是我尝试用于转换过程的代码.当我运行代码时,我收到下面的错误,我很确定这是因为我的字符串在军事(24小时)时间内有时间部分.任何人都可以帮我把字符串转换成我需要的格式吗？

谢谢!
