当尝试在 C# 中创建 Enterprise Architect 插件时，在我完成代码并在 VS 2010 中运行它之后，我可以将记录添加到数据库或删除，但是当我使用同一个项目的插件项目时但是使用允许我访问 Enterprise Architect 事件的类库，我收到以下错误：
应用程序的组件中发生了未经处理的异常。如果您单击继续，应用程序将忽略此错误并尝试继续。
尝试为 C:\Program Files\Sparx Systems\EA\DataBase\DBMetric.mdf 附加自动命名数据库失败。存在同名数据库，或无法打开指定文件或其位于 UNC 共享上。
当我去的C\...EA时候没有数据库文件夹！
这是我的app.config文件
<configuration>
<connectionStrings>
<add name="WindowsFormsApplication19.Properties.Settings.DBMetricConnectionString"
connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\DataBase\DBMetric.mdf;Integrated Security=True;User Instance=True"
providerName="System.Data.SqlClient"/>
</connectionStrings>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
</startup>
</configuration>
这是我的连接字符串代码：
public static string myConnectionString = ConfigurationManager.ConnectionStrings["WindowsFormsApplication19.Properties.Settings.DBMetricConnectionString"].ConnectionString;
有任何想法吗？
提前致谢
