Question

我已经将.Net 4.0的大型应用程序更新为.Net 4.52，它已经破坏了我使用Lucene的一些索引和搜索功能。我更新到最新的Lucene NuGet包，我不断收到以下错误。未定义类型“Lucene.Net.Index.IndexWriter”。未定义类型“Lucene.Net.Documents.Document”。未定义类型“IndexWriter”。仅举几例。搜索功能最初是由另一个开发人员编写的，所以我并不完全熟悉它，但看起来他们在将Lucene更新到3.0.3时可能已经移动了一些命名空间，但我找不到他们更新的内容。任何帮助将不胜感激！谢谢代码示例如下参考文献：

Imports Microsoft.WindowsAzure.Storage.Blob
Imports Microsoft.WindowsAzure.Storage
Imports Lucene.Net
Imports Lucene.Net.Documents
Imports Lucene.Net.Store

Imports Lucene.Net.Index
Imports Lucene.Net.Analysis

Lucene.Net.Store表示它不包含任何公共成员。

未定义Lucene.Net.Index.IndexWriter的示例函数

 Private Function IndexNewDocument(id As String, savePath As String, targetContainer As String, indexer As Lucene.Net.Index.IndexWriter, b As CloudBlockBlob) As Boolean
    Dim sw As Stopwatch = Stopwatch.StartNew

    Dim filename As String = ""
    Dim dt As DateTime = Now

    Try
        ' Retrieve the document and pull the metadata for reindexing
        Dim docReturn As DocumentReturn = DocumentDownloadAdapter.GetDocument(_StorageEndpoint, _NewDocumentContainerName, id)
        filename = docReturn.Filename
        dt = docReturn.DateAdded

        ' Get the blob reader for indexing
        Dim docReader As IBlobDocumentReader = FileProcessor.GetBlobDocumentReader(docReturn.FileBytes, docReturn.Filename, savePath)

        ' push the index to the blob storage database
        pushIndexDocument(id, filename, dt, docReader, indexer)

        sw.Stop()
        OnDocumentIndexSuccessful(id, filename, sw.Elapsed)

        Return True
    Catch ex As EmptyPDFException
        CommonCodeLib.ErrorReport("AzureStorageAccountAdapter.indexDocument", ex, "")

        ' DELETE FILE FROM NEW BLOB INDEX
        Try
            b.Delete()
        Catch exDelete As Exception
            CommonCodeLib.ErrorReport("AzureStorageAccountAdapter.indexDocument: Problem Deleting blob", exDelete, "")
        End Try

        Try
            Dim username As String = getDocumentUsername(targetContainer, id)
            EmailAdapter.SendExceptionEmail(ex, GetEmailList(ConfigurationHelper.IndexEmailToList), GetEmailList(ConfigurationHelper.IndexEmailCCList), username)
        Catch exEmail As Exception
            CommonCodeLib.ErrorReport("AzureStorageAccountAdapter.indexDocument: Problem Emailing Exception", exEmail, "")
        End Try

        Return False
    Catch ex As InvalidDocumentTypeException
        CommonCodeLib.ErrorReport("AzureStorageAccountAdapter.indexDocument", ex, "")

        ' DELETE FILE FROM NEW BLOB INDEX
        Try
            b.Delete()
        Catch exDelete As Exception
            CommonCodeLib.ErrorReport("AzureStorageAccountAdapter.indexDocument: Problem Deleting blob", exDelete, "")
        End Try

        Try
            Dim username As String = getDocumentUsername(targetContainer, id)
            EmailAdapter.SendExceptionEmail(ex, GetEmailList(ConfigurationHelper.IndexEmailToList), GetEmailList(ConfigurationHelper.IndexEmailCCList), username)
        Catch exEmail As Exception
            CommonCodeLib.ErrorReport("AzureStorageAccountAdapter.indexDocument: Problem Emailing Exception", exEmail, "")
        End Try

        Return False
    Catch ex As Exception
        CommonCodeLib.ErrorReport("AzureStorageAccountAdapter.indexDocument", ex.ToString, "")
        sw.Stop()
        OnDocumentIndexFailed(id, filename, sw.Elapsed, ex)

        Return False
    End Try
End Function
