COM Interop, the RPC server is not available in C #

try
 {
 m_COMObject. SomeMethod();
 }

 Exception(exception exception)
 {
 DisposeCOMObject();
 InitializeCOMOBject();
 COMObject.Somethod ();
 }


 public void DisposeCOMObject()
{
 m_COMObject = null;
 var process = Process.GetProcessesByNames(" COM .exe").FirstDefault();

 if(process != null)
 {
 process.kill();
 }
} 


 public void InitializeCOMObject()
{
 m_COMObject = null;
 m_COMObject = new COMObject();
}

I am using COM Interop, I am instantiating COM class objects from interop dll
So, Few objects are successfully instantiated and make remote procedure calls without any problems, but sometimes exceptions are thrown, such as RPC Server cannot be used.
The COM component I am using is written in VB, and I use it in c# This component.

So, anyone can tell me the possible cause of the problem (RPC server is unavailable) and the way to solve this problem.

I am now about this problem Very helpless.

So, if you can help me, please thank you

After reviewing my COM implementation method, I found This bug. I use a static class to initialize the COM instance, the initialization thing happens in the static constructor. Therefore, each application session must be initialized once. In this case, when the COM instance is destroyed or discarded , Calling the COM method will cause an exception (RPC Server is not available).
So, I use the following methods to overcome this problem

try
 { 
 m_COMObject.SomeMethod();
 }

 Exception(exception exception)
 {
 DisposeCOMObject();
 InitializeCOMOBject();< br /> COMObject.Somethod();
 }


 public void DisposeCOMObject()
{
 m_COMObject = null;
 var process = Process.GetProcessesByNames("COM .exe").FirstDefault();

 if(proce ss != null)
 {
 process.kill();
 }
}


 public void InitializeCOMObject()
{
 m_COMObject = null;
 m_COMObject = new COMObject();
}

If the instance of COM cannot be called, configure the instance and reinitialize COM and get Instance, then call RPC Server.
