Question

我有一个像这样的属性的控件：

public BindingList<I> X { get; private set; } = new SortableBindingList<I>();

我是一个界面。它构建良好，运行正常，但是当我将此控件添加到表单时（如果表单在同一个程序集中无关紧要），然后尝试在visual studio（2017）中打开该表单，表单是未显示，出现以下错误消息：

'I []'类型的对象无法转换为'I []'类型。

使用以下调用堆栈：

at System.RuntimeType.TryChangeType（Object value，Binder binder， CultureInfo culture，Boolean needsSpecialCast）at System.RuntimeType.CheckValue（对象值，Binder活页夹，CultureInfo culture，BindingFlags invokeAttr）at System.Reflection.RtFieldInfo.UnsafeSetValue（Object obj，Object value， BindingFlags invokeAttr，Binder binder，CultureInfo culture）at System.Runtime.Serialization.FormatterServices.SerializationSetValue（的MemberInfo fi，对象目标，对象值）at System.Runtime.Serialization.ObjectManager.CompleteObject（的ObjectHolder holder，Boolean bObjectFullyComplete）at System.Runtime.Serialization.ObjectManager.DoNewlyRegisteredObjectFixups（的ObjectHolder 持有人） System.Runtime.Serialization.ObjectManager.RegisterObject（Object obj， Int64 objectID，SerializationInfo info，Int64 idOfContainingObj， MemberInfo成员，Int32 [] arrayIndex）at System.Runtime.Serialization.Formatters.Binary.ObjectReader.RegisterObject（对象 obj，ParseRecord pr，ParseRecord objectPr，Boolean bIsString）at System.Runtime.Serialization.Formatters.Binary.ObjectReader.ParseObjectEnd（ParseRecord pr）at System.Runtime.Serialization.Formatters.Binary.ObjectReader.Parse（ParseRecord pr）at System.Runtime.Serialization.Formatters.Binary .__ BinaryParser.Run（）at System.Runtime.Serialization.Formatters.Binary.ObjectReader.Deserialize（HeaderHandler handler，__BinaryParser serParser，Boolean fCheck，Boolean isCrossAppDomain，IMethodCallMessage methodCallMessage）at System.Runtime.Serialization.Formatters.Binary.BinaryFormatter.Deserialize（流 serializationStream，HeaderHandler handler，Boolean fCheck，Boolean isCrossAppDomain，IMethodCallMessage methodCallMessage）at System.Runtime.Serialization.Formatters.Binary.BinaryFormatter.Deserialize（流 serializationStream）at System.Resources.ResXDataNode.GenerateObjectFromDataNodeInfo（DataNodeInfo dataNodeInfo，ITypeResolutionService typeResolver）at System.Resources.ResXDataNode.GetValue（ITypeResolutionService typeResolver）at System.Resources.ResXResourceReader.ParseDataNode（XmlTextReader的 reader，Boolean isMetaData）at System.Resources.ResXResourceReader.ParseXml（XmlTextReader reader）

我尝试添加

[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]

或

[Browsable(false), DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]

分别按https://stackoverflow.com/a/29720/68936和https://stackoverflow.com/a/29717/68936;

我也尝试用

替换getter-setter

private BindingList<I> myX = new SortableBindingList<I>();
public BindingList<I> myX { get { return myX; } }

根据https://stackoverflow.com/a/16657926/68936

无济于事。我已经尝试关闭所有打开的文档，关闭解决方案，重新启动visual studio，重建两个程序集，似乎没有解决这个问题。

我能够使用

[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
public BindingList<I> myX { get; private set; } = new SortableBindingList<I>();

通过编辑包含表单的 .resx文件（而不是控件）并删除看起来像这样的xml元素：

  <data name="controlName.X" mimetype="application/x-microsoft.net.object.binary.base64">
    <value>
        AAEAAAD/////AQAAAAAAAAAMAgAAAJsBSW50ZXJmYWNlc0ludmVzdG1lbnRzLCBWZXJzaW9uPTEuMC4w
        LjAsIEN1bHR1cmU9bmV1dHJhbCwgUHVibGljS2V5VG9rZW49bnVsbF1dLCBtc2NvcmxpYiwgVmVyc2lv

        AwAAAAgIAgAAAAkEAAAAAAAAAAAAAAAHBAAAAAABAAAAAAAAAAQrS2FtYVRyZW5kYS5JbnRlcmZhY2Vz
        LkludmVzdG1lbnRzLklQb3NpdGlvbgMAAAAL
</value>
  </data>

似乎只是添加DesignerSerializationVisibility.Hidden不足以从现有的.resx文件中删除现有数据节点。

'X []'类型的对象无法转换为'X []'
