ASP.net搜索功能编辑

我被要求在别人的代码中编辑搜索功能

我对这门特殊的语言没有太多的知识，虽然我确信这是一个简单的解决办法，但我不想在没有建议的情况下打破它

搜索功能返回的结果太多，其搜索部分为单词。所以搜索“e”会带回所有带有“e”的东西

我需要编辑以搜索整个单词

这是完整的代码

如果你想搜索一个单词，那么你可以使用以下方法

在构造SQL之前调用以下行

searchfor = "[^a-zA-Z]" + searchfor + "[^a-zA-Z]"

这里的想法是搜索输入的内容，其中前后都没有字母。例如，如果您输入'at'，则它与'car at usa'匹配，但与'cat'不匹配

这不是一个完美的解决方案，但只是一个想法，它可以扩展以排除更多的字符
