CRM插件：沙盒中的自定义异常 [英] CRM Plugin: Custom Exception in Sandbox

问题描述

我在沙箱中的动态CRM 2013的插件执行。

这code具有以下自定义异常类：

  [Serializable接口]
    公共类PluginValidationException：异常
    {
        公共PluginValidationException（）
        {
        }

        保护PluginValidationException（SerializationInfo中的信息，的StreamingContext上下文）
            ：基地（信息，上下文）
        {
        }

        公共PluginValidationException（字符串消息）
            ：碱（消息）
        {
        }

        公共PluginValidationException（字符串消息，异常内）
            ：基地（消息，内部）
        {
        }
    }
 

在这个异常被抛出在它导致一般性错误窗口插件，并在日志文件中没有详细说明：

未处理的异常：System.ServiceModel.FaultException`1 [Microsoft.Xrm.Sdk.OrganizationServiceFault，Microsoft.Xrm.Sdk，版本= 6.0.0.0，文化=中性公钥= 31bf3856ad364e35]：系统。 Runtime.Serialization.SerializationException：Microsoft Dynamics CRM中遇到错误。参考号码为管理员或支持：＃1355B4E4Detail：   -2147220970               调用堆栈          在Microsoft.Crm.Application.Platform.ServiceCommands.PlatformCommand.XrmExecuteInternal（）    在Microsoft.Crm.Application.Platform.ServiceCommands.CreateCommand.Execute（）    在Microsoft.Crm.Application.Platform.EntityProxy.Create（布尔performDuplicateCheck中GUID auditingTransactionId）    在Microsoft.Crm.Application.Platform.EntityProxy.Create（布尔performDuplicateCheck）    在Microsoft.Crm.Application.Platform.EntityProxy.CreateAndRetrieve（字符串[] columnSet，布尔performDuplicateCheck）    在Microsoft.Crm.Application.WebServices.InlineEdit.CommandBase.UpdateEntity（实体的实体，布尔检索）    在Microsoft.Crm.Application.WebServices.InlineEdit.SaveCommand.ExecuteCommand（字符串commandXml）    在Microsoft.Crm.Application.WebServices.InlineEdit.CommandBase.Execute（字符串commandXml）           System.Runtime.Serialization.SerializationException：Microsoft Dynamics CRM中遇到错误。参考号码为管理员或支持：＃1355B4E4   2014-04-06T02：04：30.0972001Z       [Demo.DemoPlugin：Demo.DemoPlugin.BasicCrmPlugin] [d86b89ab-f1bc-e311-9408-000c29254b18：Demo.DemoPlugin.BasicCrmPlugin：创建联系人] 的

纵观CRM跟踪日志显示以下内容：

System.Runtime.Serialization.SerializationException：组装型Demo.Helpers.PluginValidationException'Demo.DemoPlugin，版本= 1.0.0.0，文化=中性公钥= fbb51ba1e588d276'未标记为可序列化。            在Microsoft.Crm.Sandbox.SandboxAppDomainHelper.Execute（IServiceEndpointNotificationService serviceBusService，IOrganizationServiceFactory organizationServiceFactory，字符串pluginTypeName，字符串pluginConfiguration，字符串pluginSecureConfig，IPluginExecutionContext的RequestContext）            在Microsoft.Crm.Sandbox.SandboxWorker.Execute（SandboxCallInfo callInfo，SandboxPluginExecutionContext的RequestContext中GUID pluginAssemblyId，的Int32 sourceHash，字符串的AssemblyName中GUID pluginTypeId，字符串pluginTypeName，字符串pluginConfiguration，字符串pluginSecureConfig，SandboxRequestCounter和放大器; workerCounter）的

我不这样做，根据一些阅读，认为这是一个错误 - 而这是因为自定义的异常班都没有，本来值得信赖作为.NET 4（我敢使用.NET 4.5。）

有谁知道如何使将与CRM沙箱中的自定义异常类。我使用的是自定义异常类，因为我发现错误，需要区分的 InvalidPluginExecutionException 异常造成的，因为插件未正确注册。

已更新2014年4月8日

下面是code中，捕获异常，有显著简化了把它放在＃1插件：

 尝试
        {
            // TODO：prevalidation逻辑
            ValidatePluginExecution（crmContext，记录，出注册表项目）;
            // TODO：Postvalidation逻辑
        }
        赶上（PluginValidationException前）
        {
            // TODO：具体日志记录插件验证异常
            抛出新InvalidPluginExecutionException（无法验证）;
        }
        赶上（InvalidPluginExecutionException前）
        {
            logging.Write（InvalidPluginExectionException在插件验证）;
            扔;
        }
        赶上（例外前）
        {
            logging.Write（未处理Exeception在插件验证操作）;
            logging.Write（前）;
            抛出新InvalidPluginExecutionException（错误下载登录并提交给帮助台。前）;
        }
 

解决方案

我不认为你想要什么是可能的，如果你想在错误对话框，你不得不放弃 InvalidPluginExecutionException 。

处理的插件

  

有关同步插件，您可以选择显示自定义错误   通过在Web应用程序的错误对话框消息您   插件引发InvalidPluginExecutionException异常的   自定义消息字符串作为异常消息属性值

     

建议插件只传递   InvalidPluginExecutionException回到该平台。

作为一个方面，我不会理会在插件本身检查登记，它的这种情况不使一个很大的意义在2013年早在CRM 4中的插件必须手动注册的有一些道理在里面。现在我们有解决方案，正确的注册是一个开发和测试任务 - 而不是一个运行时检查

I have a Dynamics CRM 2013 plugin executing in the Sandbox.

This code has the following custom exception class:

    [Serializable]
    public class PluginValidationException : Exception
    {
        public PluginValidationException()
        {
        }

        protected PluginValidationException(SerializationInfo info, StreamingContext context) 
            : base(info, context)
        {            
        }

        public PluginValidationException(string message)
            : base(message)
        {
        }

        public PluginValidationException(string message, Exception inner)
            : base(message, inner)
        {
        }
    }

When this exception is thrown in the plugin it results in a generic error window, with no details in the log file:

Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=6.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: System.Runtime.Serialization.SerializationException: Microsoft Dynamics CRM has experienced an error.

Looking at the CRM trace log shows the following:

System.Runtime.Serialization.SerializationException: Type 'Demo.Helpers.PluginValidationException' in assembly 'Demo.DemoPlugin, Version=1.0.0.0, Culture=neutral, PublicKeyToken=fbb51ba1e588d276' is not marked as serializable. at Microsoft.Crm.Sandbox.SandboxAppDomainHelper.Execute(IServiceEndpointNotificationService serviceBusService, IOrganizationServiceFactory organizationServiceFactory, String pluginTypeName, String pluginConfiguration, String pluginSecureConfig, IPluginExecutionContext requestContext) at Microsoft.Crm.Sandbox.SandboxWorker.Execute(SandboxCallInfo callInfo, SandboxPluginExecutionContext requestContext, Guid pluginAssemblyId, Int32 sourceHash, String assemblyName, Guid pluginTypeId, String pluginTypeName, String pluginConfiguration, String pluginSecureConfig, SandboxRequestCounter& workerCounter)

I do not, based on some reading, believe this is a bug - rather it is because custom Exception classes are not, inherently trusted as of .NET 4 (I'm using .NET 4.5.)

Does anyone know how to make a custom exception class that will work with the CRM Sandbox. I'm using a custom exception class because I catch errors and need to distinguish between an InvalidPluginExecutionException an exception caused because the plug-in is incorrectly registered.

UPDATED Apr 08 2014

Here is the code in the plugin that catches the exceptions, with significant simplification for putting it on Stackoverflow:

        try
        {
            //TODO: Prevalidation Logic
            ValidatePluginExecution(crmContext, logging, out keyName);
            //TODO: Postvalidation Logic
        }
        catch (PluginValidationException ex)
        {
            //TODO: Specific logging for Plugin Validation Exception
            throw new InvalidPluginExecutionException("Did Not Validate");                    
        }
        catch (InvalidPluginExecutionException ex)
        {
            logging.Write("InvalidPluginExectionException at Plugin Validation");                    
            throw;
        }
        catch (Exception ex)
        {
            logging.Write("Unhandled Exeception During Plugin Validation Operation");
            logging.Write(ex);
            throw new InvalidPluginExecutionException("Error.  Download Log and submit to the Help Desk.", ex);                    
        }

解决方案

I don't think what you want is possible, if you want a message in that error dialog you have to throw InvalidPluginExecutionException.

Handle Exceptions in Plug-Ins

For synchronous plug-ins, you can optionally display a custom error message in the error dialog of the web application by having your plug-in throw an InvalidPluginExecutionException exception with the custom message string as the exception Message property value

It is recommended that plug-ins only pass an InvalidPluginExecutionException back to the platform.

As a side, I wouldn't bother checking the registration in the plugin itself, its a situation which doesn't make a lot of sense in 2013. Back in CRM 4 where plugins had to be manually registered there was some sense in it. Now we have solutions, the correct registration is a development and testing task - not a run time check.
