未设置为对象实例的对象引用.当通过网络访问时，但在本地工作良好

我有一个问题，我似乎不能弄清楚，我在旋转我的轮子…我有一个项目(c#多线程windows应用程序)，它是作为一个整体构建的，我的任务是打破单个组件来打破相互依赖关系。现在所有的组件都被分解了，我正在测试和调试我提出的问题，然后将其发布给QA。这是(希望)最后一个问题:

当我运行主组件时，它接受一个任务来处理，它实例化运行时组件(. dll)，然后实例化一个程序集(数据采集. dll)。程序集(数据采集. dll)是围绕控制其功能的基本组件构建的。程序集被编译并存储在网络上，并从网络上访问，因为在网络上的不同机器上运行着主组件的多个实例。当我试图访问其目录中的程序集时，我得到一个"对象引用未设置为对象的实例"…但是…当我运行本地复制的相同程序集时，它运行良好。

我不知道为什么它在本地运行而不是在整个网络上运行。我想不出我丢失的参考资料在哪里了。请帮助! !

希望我已经足够详细地描述了这个问题，为一些指导，如果你需要更多的细节，请告诉我。

编辑:包括代码片段和日志文件片段。

下面是发生问题的代码段:

string assemblyName  = moduleName;
        _log.LogMessage("DACLRuntime assemblyName: " + assemblyName);
        Assembly dacAssembly = Assembly.LoadFrom(assemblyName);
        moduleName           = Path.GetFileNameWithoutExtension(assemblyName);
        _log.LogMessage("DACLRuntime moduleName: " + moduleName);
        var dacType          = (from c in dacAssembly.GetTypes() where c.Name.EqualsIgnoreCase(moduleName) select c).First();
        _log.LogMessage("DACLRuntime dacType: " + dacType.ToString());
        if (dacType != null)
        {
            _log.LogMessage("DACLRuntime Instansiate the DACBase...");
            DACBase dac    = (DACBase)Activator.CreateInstance(dacType);
            _log.LogMessage("DACLRuntime DACBase is instantiated...");
            dac.gsDACLPath = Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location);
            _log.LogMessage("DACBase path is: " + dac.gsDACLPath);
            try
            {
                // -- Does the script exist...
                if (File.Exists(assemblyName))
                    _log.LogMessage("Script located at ==> " + assemblyName + " <==  Exists.");
                _log.LogMessage("Script Started:" + assemblyName + " orderid:" + orderId);
                dac.iPid = iPid;
                _log.LogMessage("    dac.iPid = " + iPid.ToString());
                _log.LogMessage("    Calling dac.InitAndExecute()...Passing the OrderId and the RunTime Log file (_log)...");
                dac.InitAndExecute(orderId, _log);
                _log.LogMessage("    Call to dac.InitAndExecute() sucessful...");
            }
            catch (IndexOutOfRangeException)
            {
                // Coded As per ZAM to raise error 17 if it is index out of bounds
                dac.Frame.Error = 17;
                _log.LogInformation("Index was outside the bounds of the array For " + assemblyName + " orderid:" + orderId);
            }

从日志中可以看到，当我按原样运行它时，它得到了错误。当应用程序仍在运行时(在调试器中)，我将路径覆盖到我的本地和它的工作。
