'How to solve BinaryFormatter Deserialize 3th party object Exception in C#?

In my project, I have a function which is used for loading objects from files:

public static ObjectBase LoadObject(string _filePath, string _name)
{
    ObjectBase module = null;

    try
    {
        IFormatter formatter = new BinaryFormatter();
        Stream streamRead = new FileStream(_filePath, FileMode.Open, FileAccess.Read, FileShare.None);

        object ob = formatter.Deserialize(streamRead);
        module = (ob as ObjectBase);
        streamRead.Close();
    }
    catch (Exception ex)
    {
        return null;
    }
    finally
    {
    }
    return module;
}

Everytime when I run this function, I hit exception:

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.InvalidOperationException: Operation is not valid due to the current state of the object.

Anyone have ideas? I really appreciate your helps!

I had the same problem when trying to load vpp file (cognex) using this code line..

cogJobManager = CogSerializer.LoadObjectFromFile(jobFilesPath) as CogJobManager;

the solution for me was to uncheck the "Prefer 32-bit" from the project properties under Build tab, and compile it as Any CPU

after that the problem was solved
