在C＃中以新程序版本读取旧剪贴板数据 [英] Reading old clipboard data in new program version in C#

问题描述

我们有一个旧程序版本，在该版本中我们将可序列化的类放入剪贴板。对于这个示例，我们可以这样说：

We have an old program version where we put a serializable class into the clipboard. For this example lets say something like this:

namespace ClipboardLibrary
{
    [Serializable]
    public class ClipboardData
    {
        public string Content { get; set; }
    }
}

现在在新版本中为此保留它示例简单的类看起来类似，只是名称空间已更改，如下所示：

Now in the new version to keep it for this example simple the class looks the same except the namespace was changed like so:

namespace ClipboardLibrary.OtherNamespace
{
    [Serializable]
    public class ClipboardData
    {
        public string Content { get; set; }
    }
}

当我从旧版本复制时-其中只需调用 SetData（someKey，剪贴板数据）并尝试通过 Clipboard.GetData（someKey）我得到一个序列化异常：

When I copy now from the old version - where it is done by simply call SetData(someKey, clipboardData) and try to get the deserialize the data via Clipboard.GetData(someKey) I get a serialization exception:

System.Runtime.Serialization.SerializationException was unhandled
  HResult=-2146233076
  Message=Der für die Deserialisierung benötigte Typ "ClipboardLibrary.ClipboardData" kann nicht geladen werden.

抱歉，这里的德语文本。它说的是找不到类型 ClipboardLibrary.ClipboardData ，这很明显。

I am sorry of the German text here. What it says is that the type ClipboardLibrary.ClipboardData could not be found, which makes obvious sense.

有可能以某种方式检索数据吗？

Is there a possibility to retrieve the data anyway somehow?

推荐答案

您可以在新的程序集中引用旧程序集并获得 ClipboardLibrary.ClipboardData Type 通过反序列化，没有例外。并在新的程序集转换器中实现，从 ClipboardLibrary.ClipboardData 到 ClipboardLibrary.OtherNamespace.ClipboardData 。

You can reference old assembly in the new one and obtain ClipboardLibrary.ClipboardData Type via deserialization without exceptions. And implement in the new assembly convertor from ClipboardLibrary.ClipboardData to ClipboardLibrary.OtherNamespace.ClipboardData.
