我在Sandbox中执行了一个Dynamics CRM 2013插件。
此代码具有以下自定义异常类:
[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)
{
}
}
当插件中抛出此异常时,会导致一般错误窗口,日志文件中没有详细信息:
未处理的异常: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遇到错误。管理员或支持的参考编号:#1355B4E4详细信息: -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(Boolean performDuplicateCheck,Guid auditingTransactionId) 在Microsoft.Crm.Application.Platform.EntityProxy.Create(Boolean performDuplicateCheck) 在Microsoft.Crm.Application.Platform.EntityProxy.CreateAndRetrieve(String [] columnSet,Boolean performDuplicateCheck) 在Microsoft.Crm.Application.WebServices.InlineEdit.CommandBase.UpdateEntity(实体实体,布尔检索) 在Microsoft.Crm.Application.WebServices.InlineEdit.SaveCommand.ExecuteCommand(String commandXml) 在Microsoft.Crm.Application.WebServices.InlineEdit.CommandBase.Execute(String commandXml) System.Runtime.Serialization.SerializationException:Microsoft Dynamics CRM遇到错误。管理员或支持的参考编号:#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]
查看CRM跟踪日志显示以下内容:
System.Runtime.Serialization.SerializationException:输入' Demo.Helpers.PluginValidationException'在汇编' Demo.DemoPlugin,Version = 1.0.0.0,Culture = neutral,PublicKeyToken = fbb51ba1e588d276'未标记为可序列化。 在Microsoft.Crm.Sandbox.SandboxAppDomainHelper.Execute(IServiceEndpointNotificationService serviceBusService,IOrganizationServiceFactory organizationServiceFactory,String pluginTypeName,String pluginConfiguration,String pluginSecureConfig,IPluginExecutionContext requestContext) 在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)
基于一些阅读,我不相信这是一个错误 - 而是因为自定义Exception
类本身不受.NET 4(我使用.NET 4.5)的信任。 )
有没有人知道如何制作适用于CRM Sandbox的自定义异常类。我使用自定义异常类,因为我发现错误并需要区分InvalidPluginExecutionException
因插件注册错误而导致的异常。
2014年4月8日更新
以下是插件中捕获异常的代码,并将其放在Stackoverflow上进行了大量简化:
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);
}

我不认为你想要什么是可能的,如果你想在那个错误对话框中留言,你必须抛出InvalidPluginExecutionException
。
对于同步插件,您可以选择显示自定义错误 通过让您的Web应用程序的错误对话框中的消息 插件抛出一个InvalidPluginExecutionException异常 自定义消息字符串作为异常消息属性值
建议插件只能通过 InvalidPluginExecutionException返回平台。
作为一方,我不打算检查插件本身的注册情况,这种情况在2013年没有多大意义。回到CRM 4,其中插件必须手动注册它有一些意义。现在我们有解决方案,正确的注册是开发和测试任务 - 而不是运行时检查。
答案 1 :(得分:2)
经过一些额外的测试,这是我能够确定的:
显然,只有在明确这样做的情况下,才能访问堆栈跟踪以查找异常。从沙盒插件中抛出异常时,只要异常是CRM平台知道的异常,就不会显示异常的堆栈跟踪。 (不知道它在做什么,这里,但我猜测它正在查看异常的类型,并以不同的方式处理不同的类型)。如果类型未知,则会导致CRM尝试序列化a中不允许的异常,因为它使用反射(为什么必须序列化,不确定)。
这是一个示例插件,其中包含一些有效的示例,还有一些没有实例:
public class TestPlugin: IPlugin
{
public void Execute(IServiceProvider serviceProvider)
{
try
{
OtherMethod();
}
catch (Exception ex)
{
var trace = (ITracingService)serviceProvider.GetService(typeof (ITracingService));
trace.Trace("Throwing Plugin");
// Doesn't work
throw new InvalidPluginExecutionException("Error ", ex);
}
}
// Works:
//public void Execute(IServiceProvider serviceProvider)
//{
//try
//{
//OtherMethod();
//}
//catch (Exception ex)
//{
//var trace = (ITracingService)serviceProvider.GetService(typeof(ITracingService));
//trace.Trace("Throwing Plugin");
//throw new InvalidPluginExecutionException("Error " + ex);
//}
//}
// Doesn't Work:
//public void Execute(IServiceProvider serviceProvider)
//{
// try
// {
// OtherMethod();
// }
// catch (Exception ex)
// {
// throw;
// }
//}
// Doesn't Work:
//public void Execute(IServiceProvider serviceProvider)
//{
// try
// {
// OtherMethod();
// }
// catch (Exception ex)
// {
// throw new InvalidPluginExecutionException("Error", ex);
// }
//}
public void OtherMethod()
{
throw new MyException();
}
}
public class MyException : Exception
{
}
所以回答你的问题:我编写了一个异常处理程序,以便能够遍历内部异常并确定它是否有效抛出:
/// <summary>
/// Exception Handler For Exceptions when executing in Sandbox Isolation Mode
/// </summary>
public class ExceptionHandler
{
/// <summary>
/// Determines whether the given exception can be thrown in sandbox mode.
/// Throws a Safe if it can't
/// </summary>
/// <param name="ex">The ex.</param>
/// <returns></returns>
/// <exception cref="InvalidPluginExecutionException"></exception>
/// <exception cref="Exception"></exception>
public static bool CanThrow(Exception ex)
{
var exceptionRootTypeIsValid = IsValidToBeThrown(ex);
var canThrow = exceptionRootTypeIsValid;
var innerException = ex.InnerException;
// While the Exception Types are still valid to be thrown, loop through all inner exceptions, checking for validity
while (canThrow && innerException != null)
{
if (IsValidToBeThrown(ex))
{
innerException = innerException.InnerException;
}
else
{
canThrow = false;
}
}
if (canThrow)
{
return true;
}
var exceptionMessage = ex.Message +
(ex.InnerException == null
? string.Empty
: " Inner Exception: " + ex.InnerException.ToStringWithCallStack());
// ReSharper disable once InvertIf - I like it better this way
if (exceptionRootTypeIsValid)
{
// Attempt to throw the exact Exception Type, with the
var ctor = ex.GetType().GetConstructor(new[] { typeof(string) });
if (ctor != null)
{
throw (Exception) ctor.Invoke(new object[] { exceptionMessage });
}
}
throw new Exception(exceptionMessage);
}
/// <summary>
/// Determines whether the specified ex is valid to be thrown.
/// Current best guess is that it is not
/// </summary>
/// <param name="ex">The ex.</param>
/// <returns></returns>
private static bool IsValidToBeThrown(Exception ex)
{
var assembly = ex.GetType().Assembly.FullName.ToLower();
return assembly.StartsWith("mscorlib,") || assembly.StartsWith("microsoft.xrm.sdk,");
}
}
这可以从插件中最重要的try catch调用,如下所示:
catch (InvalidPluginExecutionException ex)
{
context.LogException(ex);
// This error is already being thrown from the plugin, just throw
if (context.PluginExecutionContext.IsolationMode == (int) IsolationMode.Sandbox)
{
if (Sandbox.ExceptionHandler.CanThrow(ex))
{
throw;
}
}
else
{
throw;
}
}
catch (Exception ex)
{
// Unexpected Exception occurred, log exception then wrap and throw new exception
context.LogException(ex);
ex = new InvalidPluginExecutionException(ex.Message, ex);
if (context.PluginExecutionContext.IsolationMode == (int)IsolationMode.Sandbox)
{
if (Sandbox.ExceptionHandler.CanThrow(ex))
{
// ReSharper disable once PossibleIntendedRethrow - Wrap the exception in an InvalidPluginExecutionException
throw ex;
}
}
else
{
// ReSharper disable once PossibleIntendedRethrow - Wrap the exception in an InvalidPluginExecutionException
throw ex;
}
}
我认为这是一个实际的错误,我已经向微软公开了支持票,我们将看看他们是否同意......
<强>更新!! 强>
我与微软创建了一张票:(不确定这些数字是什么意思,但他们在主题中,希望将来对某人有益:REG:115122213520585 SRXCAP:1318824373ID)。他们确实证实了CRM for Sandboxed插件不支持自定义异常。
请对此Connect Ticket进行投票,让Microsoft修复此问题或至少更好地处理它!
