初始化RavenDb-Embedded时出现EsentFileNotFoundException.FileNotFound异常

Question

在EmbeddableDocumentStore类上调用Initialize时,我遇到了一个非常令人沮丧的错误.这是一个尝试在c:\ temp\ravenDb启动或初始化RavenDB数据库的WPF应用程序.

我的代码是:

EmbeddableDocumentStore _documentStore = new EmbeddableDocumentStore()
{
    DataDirectory = @"C:\temp\RavenDb"
};

using (_documentStore.Initialize())
{

}

相当简单.在调用Initialize()时发生错误.这是完整的错误:

Microsoft.Isam.Esent.Interop.EsentFileNotFoundException occurred
Message=File not found
Source=Esent.Interop
StackTrace:
    at Microsoft.Isam.Esent.Interop.Api.Check(Int32 err) in C:\Work\ravendb\SharedLibs\Sources\managedesent-61618\EsentInterop\Api.cs:line 2736
InnerException: 

令人沮丧的是,当我创建一个新的WPF应用程序并使用相同的代码进行复制时,它可以正常工作,并且能够初始化和创建基本文件.然后,当我回到我的主WPF应用程序时 - 数据库现在能够初始化(因为文件已经创建),但任何Session.Query调用都会导致以下错误:

System.IO.FileNotFoundException occurred
Message=segments.gen
Source=Lucene.Net
StackTrace:
   at Lucene.Net.Store.RAMDirectory.OpenInput(String name) in z:\Libs\lucene.net\src\core\Store\RAMDirectory.cs:line 301
InnerException: 

编辑:完整代码:从后台工作者委托中调用:

private void RefreshGrid()
{
    BackgroundWorker bw = new BackgroundWorker();
    bw.DoWork += new DoWorkEventHandler(bw_DoWork);            
    bw.RunWorkerCompleted += new RunWorkerCompletedEventHandler(bw_RunWorkerCompleted);
    if (bw.IsBusy != true)
    {
        bw.RunWorkerAsync(_domainType);
    }
}

void bw_DoWork(object sender, DoWorkEventArgs e)
{
    e.Result = EventStoreInstance.Instance.GetAggregateRoots((Type)e.Argument);
}

然后调用GetAggregateRoots:

//Called in class ctor:
_publisher = publisher;
_documentStore = new EmbeddableDocumentStore()
{
    DataDirectory = _dataDir // is "C:\temp\RavenDb"
};

public List<AggregateRootModel> GetAggregateRoots(Type AggregrateRootType)
{
    using (_documentStore.Initialize())
    {
        using (var session = _documentStore.OpenSession())
        {
            var aggregateRoots = session.Query<AggregateRootModel>()
                    .Where(p => p.Type == AggregrateRootType.AssemblyQualifiedName).ToList();
            return aggregateRoots;
        }
    }
}

这些是预期的,它们在RavenDB内部处理.您正在看到它们,因为您正在调试器中运行并停止任何异常.
