我在SQL Server 2012 SP1 Reporting Services实例中设置了一个订阅,该实例将34MB文件导出到Excel 2007-2013 XLSX OpenXML呈现扩展名。订阅引发以下错误:
System.IO.IsolatedStorage.IsolatedStorageException:无法确定域的身份。
我验证了可以将报告从报告管理器导出到Excel 2007-2013 XLSX OpenXML呈现扩展名,而不会出现问题。仅当通过订阅执行报告时,才会发生此错误。我对此进行了研究,并在网上找到了以下建议:

最佳答案
您可以在此处找到解决方案:http://rekiwi.blogspot.com/2008/12/unable-to-determine-identity-of-domain.html
在COM组件中,使用适当的证据创建一个新的AppDomain并执行其中的代码。
这是一个为我解决问题的代码示例:
AppDomainSetup setup = new AppDomainSetup();
setup.ApplicationBase = AppDomain.CurrentDomain.BaseDirectory.ToString();
//Then we need our evidence
System.Security.Policy.Evidence evidence = new System.Security.Policy.Evidence();
evidence.AddHost(new System.Security.Policy.Zone(System.Security.SecurityZone.MyComputer));
//Now we can fire up an AppDomain running with that evidence.
AppDomain domain = AppDomain.CreateDomain("YourDll.YourClass", evidence, setup);
YourDll.YourClass yourclass = (YourDll.YourClass)domain.CreateInstanceAndUnwrap(typeof(YourDll.YourClass).Assembly.FullName, typeof(YourDll.YourClass).FullName);
yourclass.CallYourMethod();
您想要跨AppDomain编码(marshal)的任何类型都必须标记为[Serializable()],并且必须继承自MarshalByRefObject。
例如:
namespace YourDll
{
[Serializable()]
public class YourClass: MarshalByRefObject
{
...
