SolrNet 异常：文档缺少必需的 uniqueKey 字段：id
SolrNet Exception: Document is missing mandatory uniqueKey field: id
我正在开发一个 MVC 应用程序，使用 SolrNet（版本 0.4.0.2002）实现 Solr（最新版本 solr-4.10.3）。我是 Solr/SolrNet 的新手，使用 http://crazorsharp.blogspot.in/2010/01/full-text-search-using-solr-lucene-and.html 教程进行练习。使用 SolrNet.dll.
索引数据库 table 数据时出现以下错误
An exception of type 'SolrNet.Exceptions.SolrConnectionException' occurred in SolrNet.dll but was not handled in user code

这是我的错误。我指定了错误的 URL 来映射核心。所以，我改变了
Startup.Init<EmpSolr>("http://localhost:8888/solr/#/mytestcore");
到
Startup.Init<EmpSolr>("http://localhost:8888/solr/mytestcore");
删除了 URL 内的额外 #。
