Question

我有一个名为DocumentExplorerControl的自定义用户控件，它有几个属性，其中一个叫做HistoryList。如果我对包含此控件的任何表单进行任何更改，则构建将失败并显示以下错误：

Invalid Resx file. Could not load type System.Collections.Generic.List`1[[xxxxxx.DocumentManager.IHistoryObject, xxxxxx, Version=4.0.5207.25065, Culture=neutral, PublicKeyToken=null]], mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 which is used in the .RESX file.

我可以双击错误，它会转到.resx文件中的问题：

  <data name="documentsList.HistoryList" mimetype="application/x-microsoft.net.object.binary.base64">
    <value>
        AAEAAAD/////AQAAAAAAAAAMAgAAAJkBQURNU19EZXNrdG9wLCBWZXJzaW9uPTQuMC41MjA3LjI1MDY1

  </data>

这是从此控件添加到.resx文件的唯一属性，如果我删除此添加的数据部分，则应用程序构建并运行正常。

Visual Studio 2012和2013在两台不同的计算机和两个不同的用户上都出现此问题。损坏的.resx文件不会阻止设计器中的任何内容正常工作。有没有人知道可能导致这种情况的原因？我在下面添加了HistoryList的所有属性的签名。

HistoryList：

Public Property HistoryList As List(Of IHistoryObject)

IHistoryObject：

Public Interface IHistoryObject
    Property FolderList As List(Of IFolder)
    Property DocumentList As List(Of IDocument)
    Property DefaultHandler As IDocumentHandler
    Property FolderName As String
End Interface

的iFolder：

Public Interface IFolder
    Property FolderName() As String
    Property SubFolders() As List(Of IFolder)
    Property Documents() As List(Of IDocument)
    Property DefaultDocumentHandler() As IDocumentHandler
End Interface

的IDocument：

Public Interface IDocument
    Property DocumentName() As String
    Property DocumentType() As DocumentType
    Property DocumentLocation() As DocumentLocation
    Property ScreenLocation() As ScreenLocation
    Property DocumentIdentifier() As String
    Property Compressed() As Boolean
    Property DocumentHandler() As IDocumentHandler
    Property UsedDocumentId() As Integer
    Property PrivateDocument() As Boolean
    Property SavedDate() As DateTime
    Property KnowledgeLakeDocumentTypeId() As Integer?
    Property KnowledgeLakeDocumentClassId() As Integer?
    Property RequiresFollowUp() As Boolean
    Property Comments() As String
    Property DevelopmentKey() As Integer
    Property Version() As Integer
    Property MonitoringId() As Integer?
    Property FollowUpDate() As Date?
    Property FollowUpUsers As List(Of Integer)
End Interface

IDocumentHandler：

Public Interface IDocumentHandler
    Sub Open(document As IDocument)
    Sub OpenVersion(sourceTableId As Integer, fileName As String)
    Function Delete(document As IDocument, Optional saveHistory As Boolean = True) As DocumentAddReturnData
    Sub SaveToDisk(document As IDocument, filePath As String, openWhenDone As Boolean)
    Function Add(documentBinary As Byte(), ByRef document As IDocument) As DocumentAddReturnData
    Function Replace(existingDocument As IDocument, newDocument As Byte(), fileName As String) As DocumentAddReturnData
    Function Replace(documentId As Integer, newDocument As Byte()) As DocumentAddReturnData
    Function FileNameExists(fileName As String, Optional developmentKey As Integer = 0, Optional monitoringKey As Integer = 0) As DocumentConstants.FileNameExists
    Function FilePathExists(filePath As String, Optional developmentKey As Integer = 0, Optional monitoringKey As Integer = 0) As DocumentConstants.FileNameExists
    Function AppendFileNumber(fileName As String, Optional developmentKey As Integer = 0, Optional monitoringKey As Integer = 0) As String
End Interface

Answer 1

版本= 4.0.5207.25065

这是导致错误的原因。您将允许包含DocumentManager.IHistoryObject实现类型的程序集的[AssemblyVersion]属性自动递增。它看起来类似于AssemblyInfo.vb源文件中的<Assembly: AssemblyVersion("4.0.*")>。因此，每次重建时，程序集都会获得不同的版本号。这会对序列化数据造成严重破坏，它仍然包含使用原始版本号序列化的数据。因此不再兼容。设计人员在尝试反序列化.resx文件中的数据时会失败。

因此，如果您打算保留.resx文件，那么您需要禁用此自动递增。然而，听起来这是偶然的，你实际上并不希望这种情况发生。使用DesignMode属性测试是一种解决方法，但它不是正确的。您只需告诉设计人员从不持久保存数据。您可以使用以下属性执行此操作：

    <DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)> _
    <Browsable(False)> _
    Public Property History As List(Of IHistoryObject)

[Browsable]属性还可以在“属性”窗口中编辑属性时防止发生意外。

Answer 2

虽然HistoryList的签名没有初始化新集合，并且控件的构造函数没有初始化新的集合，但是从控件的load事件调用的函数确实初始化了一个新集合，所以我不得不使用{{1避免初始化。

Visual Studio错误地将数据添加到Resx文件
