无法将'x'类型的对象转换为'x'类型

本文介绍了无法将'x'类型的对象转换为'x'类型的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

大家好， 我已经生成（使用xsd）报告的c＃代码版本 定义用于报告服务中的2005版报告。我 在本地使用它，我能够反序列化已创建的 报告。然后我将代码（仅）移动到我的主项目中。我访问 rdlc文件就好了，我可以读它们没问题，但是一分钟我就试试以下内容我得到了上面的错误， _reportDef =（Rdl.Report）ser.Deserialize（fileStream）; 我不知道为什么会出现这种情况....任何人都可以放弃任何关于这个问题，这是什么意思？ 万分感谢!!

Hi everyone, I have generated (using xsd) the c# code version of the report definition used for 2005 version of reports in reporting services. I was using it locally and I was able to deserialize already created reports. I then move the code (only) into my main project. I access the rdlc files just fine, i can read them no problem, but the minute I try the following I get the above error, _reportDef = (Rdl.Report)ser.Deserialize(fileStream); I have no idea why this might be the case....can anyone shed any light on the matter? Thanks a million!!

序列化数据可能说明了类型所属的汇编， 和反序列化将尊重这一点。然后你试着把它投到 a不同的类型 - 一个在你的主项目中。 Jon

The serialized data probably says which assembly the type belongs to, and deserialization will honour that. You''re then trying to cast it to a different type - one which is within your main project. Jon

您好 ro*****@gmail ， 检查反序列化对象是否等于铸造（完整类型信息，使用 调试器）。 亲切的问候，Alex Meleta [TechBlog] devkids.blogspot Hi ro*****@gmail, Checks that a deserialized object is equal to casted (full type info, using debugger).

你可能想要在另一种类型中反序列化。 这样做： Console.WriteLine（_reportDef.GetType（）。FullName）; object o = ser.Deserialize（fileStream）; Console.WriteLine（_o.GetType （）.FullName）; 看看是否有任何区别。

Must probably you are trying to deserialize in another type. Do this: Console.WriteLine( _reportDef.GetType().FullName); object o = ser.Deserialize(fileStream); Console.WriteLine( _o.GetType().FullName); And see if there is any difference.
