Run Base Batch call c#

hi,

i  have a class that  calls  c# class.  i have  dll reference in ax .   it  shows error  and  is not completing successfully;

Microsoft.Dynamics.Ax.Xpp.ErrorException: Exception of type 'Microsoft.Dynamics.Ax.Xpp.ErrorException' was thrown.
   at Dynamics.Ax.Application.BatchRun.runJobStaticCode(Int64 batchId) in BatchRun.runJobStaticCode.xpp:line 42
   at Dynamics.Ax.Application.BatchRun.runJobStatic(Int64 batchId) in BatchRun.runJobStatic.xpp:line 13
   at BatchRun::runJobStatic(Object[] )
   at Microsoft.Dynamics.Ax.Xpp.ReflectionCallHelper.MakeStaticCall(Type type, String MethodName, Object[] parameters)
   at BatchIL.taskThreadEntry(Object threadArg)

do you know  if it is possible to call  c#  code from  run base batch class ?  it works  if i don't call that method.

c#  method is ok too. it works without run base batch.
