我一直在研究一个C＃控制台应用程序，它使用了项目中引用的许多第三方dll。
一切都运行正常，但有一天我的Windows 7操作系统因为自动更新Windows而更新，之后这个应用程序代码开始崩溃，代码调用实际访问数据库的第三方dll。
我将系统恢复到以前的状态，应用程序再次正常运行，但Windows更新再次运行，应用程序再次在同一位置开始崩溃。
我不能停止Windows更新，因为它的公司提供笔记本电脑，我无法更改设置，以便不再发生Windows更新。我没有这个第三方dll的代码。
我可以在这里为你提供app.config ...

我的应用程序崩溃或发出异常的代码如下：
public DataSet GetData(string statementId, string parameter)
{
object[] param = null;
DataSet ds = null;
try
{
if (parameter != null)
{
param = new object[1];
param[0] = parameter;
ds = DataAccessFaçadeAdapter.ExecuteStatementForDataSet(statementId, param);
}
else
{
ds = ExecuteStoredProcedure(statementId);
}
}
catch (Exception ex)
{
Tracer.Trace(TraceLevel.Error, "GetData() Exception is" + ex.Message);
}
return ds;
}
这里以下行是我得到异常的地方，因为这个方法写在第三方dll中，我没有任何代码
ds = DataAccessFaçadeAdapter.ExecuteStatementForDataSet(statementId, param);
例外情况详情如下：
- InnerException {"Object reference not set to an instance of an object."} System.Exception {System.NullReferenceException}
Message "Object reference not set to an instance of an object." string
Stack Trace如下：

at IQOR.AA.BackgroundTask.Exporter.GetData(String statementId, String parameter) in C:\\AutomationAnywhere_OLD_CODE\\AutomationAnywhere_OLD\\IQOR.AA.BackgroundTask - Copy\\IQOR.AA.BackgroundTask\\Exporter.cs:line 433
第三方dll的堆栈跟踪如下：
at Cognizant.CAFE.FoundationServices.Data.AdoHelperFactory.GetConnectionString(String providerName)
at Cognizant.CAFE.FoundationServices.Data.AdoHelperFactory.CreateHelper(String providerName)
at Cognizant.CAFE.FoundationServices.Data.AdoHelperFactory.CreateHelper()
at Cognizant.CAFE.Frameworks.FoundationAbstraction.Adapters.CAFE.DataAccessAdapter..ctor()
请告知如何解决。
答案 0 :(得分：0)
确定第三方DLL是否有更新。通常系统更新针对发现的安全漏洞，而这个目标dll 可能存在一些与相关的问题。
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可能具有最新方法的.Net 4。
