卡住了“找不到类型”使用CreateInstance（）的错误 [英] Stuck with "Cannot find type" error using CreateInstance()

问题描述

我在C＃项目的连接实用程序中尝试使用 .CreateInstance（），同时序列化XML。 .Unwrap（）用于展开可序列化的返回类型，并获取我正在尝试创建的类型的实例。

I am trying to use .CreateInstance() in a connection utility in a C# project, while serializing XML. .Unwrap() is used to unwrap the serializable return type and get an instance of the type I'm trying to create.

String fileToLoad = @"D:\RPMOpen\svnCobra\conversion\aui\Model\bin\Debug\RPM_Model";
String file = Path.GetFileName(fileToLoad);
AbstractResponseMessageData response = 
    (AbstractResponseMessageData)Activator.CreateInstance(file, responseName).Unwrap();

我的程序集 RPM_Model @D：\RPMOpen\svnCobra\conversion\aui\Model\bin\Debug\RPM_Model加载正常，但由于类型 ARC_LOGONRS in responseName 我收到以下错误：

My assembly RPM_Model at @"D:\RPMOpen\svnCobra\conversion\aui\Model\bin\Debug\RPM_Model" loads fine, but as a result of the type ARC_LOGONRS in responseName I get the following error:

方法中的错误ConnectUtil.Execute：
无法从程序集 RPM_Model，Version = 1.0.0.0加载类型 ARC_LOGONRS 文化=中立，PublicKeyToken = null 。

Error in method ConnectUtil.Execute: Could not load type ARC_LOGONRS from assembly RPM_Model, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null.

现在，这就是为什么我被困在错误上：



1。我 引用错误中指定的程序集。

2。 我的GAC中的任何内容都不会覆盖我的 / Debug中的.dll / / c $ c >文件夹。

3。我确保我有正确的.dll版本。

4。 .dll没有其他的依赖关系。

5。我的项目和.dll都有相同的目标平台。

6。我知道我正好引用了程序集，就好像我把 ARCLOGON_RS 在我的代码中，并将鼠标悬停在上面我看到

Now, this is why I am stuck on the error:

1. I did reference the assembly specified in the error.
2. There is not anything in my GAC overriding the .dll in my /Debug folder.
3. I have ensured that I have the correct version of the .dll.
4. The .dll has no other dependencies.
5. Both my project and the .dll have the same target platform.
6. I know that I am referencing the assembly properly, as if I place ARCLOGON_RS in my code and hover over it I see

class RPM.Model.Data.ARCLOGON_RS

class RPM.Model.Data.ARCLOGON_RS

，我可以 f12 专注于查看它的属性。

7。我已经清理并重建了两种解决方案。

8。类型 具有公共默认构造函数，该类是public。

9。。参考节点中的.dll 是。

10。我 将正确的程序集名称作为参数传递。

and I can f12 focus on it to see it's properties.
7. I have cleaned and rebuilt both solutions.
8. The type does have a public default constructor, and the class is public.
9. The .dll is in the reference node.
10. I do have the right Assembly Name passed as a parameter.

我的问题是，如果任何人有任何其他想法，为什么我的项目可能会抛出这个错误，以及我可以如何解决它，因为我已经完全用完了诊断。

My question is if anyone has any other idea as to why my project may be throwing this error, and how I may go about fixing it, as I have completely run out of diagnoses.

非常感谢任何帮助。

推荐答案

将typeName提供给 CreateInstance（）完整的类型。尽管我的错误看起来好像在 RPM.Model.Data 中看起来像我想要的，但显然不是。编辑 responseName 为 RPM.Model.Data.ARC_LOGONRS 而不是简单的 ARC_LOGONRS 是克服错误所必需的。

When supplying the typeName to CreateInstance() I had to hardcode the full type. Despite my error looking as though it is looking within RPM.Model.Data as I would like it to, it apparently wasn't. Editing responseName to be RPM.Model.Data.ARC_LOGONRS instead of simply ARC_LOGONRS was all that was necessary to overcome the error.
