C# 访问第三方dll时调用目标引发的异常

c#

C# 访问第三方dll时调用目标引发的异常,c#,.net-3.5,console-application,nullreferenceexception,dll-reference,C#,.net 3.5,Console Application,Nullreferenceexception,Dll Reference,我一直在开发一个C#console应用程序，它使用项目中引用的许多第三方DLL 一切正常，但有一天我的windows 7操作系统因为自动windows更新而更新，此后，该应用程序代码开始在调用实际访问数据库的第三方dll的代码处崩溃 我将系统恢复到以前的状态，应用程序再次正常工作，但windows update再次运行，应用程序再次在同一位置崩溃 我不能停止windows update，因为它是公司提供的笔记本电脑，我不能更改设置，以使windows update不再发生。我没有这个第三方dll

我一直在开发一个C#console应用程序，它使用项目中引用的许多第三方DLL

一切正常，但有一天我的windows 7操作系统因为自动windows更新而更新，此后，该应用程序代码开始在调用实际访问数据库的第三方dll的代码处崩溃

我将系统恢复到以前的状态，应用程序再次正常工作，但windows update再次运行，应用程序再次在同一位置崩溃

我不能停止windows update，因为它是公司提供的笔记本电脑，我不能更改设置，以使windows update不再发生。我没有这个第三方dll的代码

我可以在这里为您提供app.config

下面这一行是我得到异常的地方，因为这个方法是在我没有任何代码的第三方dll中编写的

ds = DataAccessFaçadeAdapter.ExecuteStatementForDataSet(statementId, param);
例外情况详情如下：

请建议如何解决。

确定第三方DLL是否有更新。通常系统会更新目标发现的安全漏洞，此目标dll可能存在一些相关问题

否则，您可能希望实现不同的数据访问方法，甚至将应用程序移动到.Net 4，该应用程序可能具有最新的方法。

您的目标是.Net的哪个版本？我的目标是.Net 3.5版。我还添加了一个显示异常详细信息的图像。也许这对理解我所面临的问题有些帮助。嗨，亲爱的，我想你是对的，这可能是因为一些安全漏洞，在windows update期间安装了很多安全补丁。但我们无法获得此第三方dll的更新版本。我已将目标框架更改为.NET 4、4.5和4.6，但问题仍然存在。我也无法更改数据访问代码，因为此项目中有多个第三方DLL。我在datasets和datareader中使用SimpleADO.NET创建了一个简单的应用程序，并从同一个数据库访问数据，一切都很好。如果第三方dll无法更新，请在这里帮助我了解更多…@ParasChaudhary；您唯一的做法是替换使用它的代码，并构建一个没有它的新应用程序。
