插件CRM动态2015
本文关键字:2015 动态 CRM 插件 | 更新日期: 2023-09-27 18:13:19
我正在尝试创建一个简单的插件并将其注册到我的MSDN CRM -解决方案。我有微软CRM SDK和微软解决方案管理器来帮助我。
当我创建一个项目时,CRM解决方案管理器提供了一个基本插件,但缺乏任何逻辑(ofc)。
在这个基础插件的执行方法下面我把逻辑?如果可能的话?
/// <summary>
/// Executes the plug-in.
/// </summary>
/// <param name="serviceProvider">The service provider.</param>
/// <remarks>
/// For improved performance, Microsoft Dynamics CRM caches plug-in instances.
/// The plug-in's Execute method should be written to be stateless as the constructor
/// is not called for every invocation of the plug-in. Also, multiple system threads
/// could execute the plug-in at the same time. All per invocation state information
/// is stored in the context. This means that you should not use global variables in plug-ins.
/// </remarks>
public void Execute(IServiceProvider serviceProvider)
{
if (serviceProvider == null)
{
throw new ArgumentNullException("serviceProvider");
}
// Construct the Local plug-in context.
LocalPluginContext localcontext = new LocalPluginContext(serviceProvider);
localcontext.Trace(string.Format(CultureInfo.InvariantCulture, "Entered {0}.Execute()", this.ChildClassName));
try
{
// Iterate over all of the expected registered events to ensure that the plugin
// has been invoked by an expected event
// For any given plug-in event at an instance in time, we would expect at most 1 result to match.
Action<LocalPluginContext> entityAction =
(from a in this.RegisteredEvents
where (
a.Item1 == localcontext.PluginExecutionContext.Stage &&
a.Item2 == localcontext.PluginExecutionContext.MessageName &&
(string.IsNullOrWhiteSpace(a.Item3) ? true : a.Item3 == localcontext.PluginExecutionContext.PrimaryEntityName)
)
select a.Item4).FirstOrDefault();
if (entityAction != null)
{
localcontext.Trace(string.Format(
CultureInfo.InvariantCulture,
"{0} is firing for Entity: {1}, Message: {2}",
this.ChildClassName,
localcontext.PluginExecutionContext.PrimaryEntityName,
localcontext.PluginExecutionContext.MessageName));
entityAction.Invoke(localcontext);
// now exit - if the derived plug-in has incorrectly registered overlapping event registrations,
// guard against multiple executions.
return;
}
}
catch (FaultException<OrganizationServiceFault> e)
{
localcontext.Trace(string.Format(CultureInfo.InvariantCulture, "Exception: {0}", e.ToString()));
// Handle the exception.
throw;
}
finally
{
localcontext.Trace(string.Format(CultureInfo.InvariantCulture, "Exiting {0}.Execute()", this.ChildClassName));
}
}
您可以将代码剥离为:
public void Execute(IServiceProvider serviceProvider)
{
LocalPluginContext localcontext = new LocalPluginContext(serviceProvider);
localcontext.Trace(string.Format(CultureInfo.InvariantCulture, "Entered {0}.Execute()", this.ChildClassName));
try
{
}
catch (FaultException<OrganizationServiceFault> e)
{
localcontext.Trace(string.Format(CultureInfo.InvariantCulture, "Exception: {0}", e.ToString()));
// Handle the exception.
throw;
}
finally
{
localcontext.Trace(string.Format(CultureInfo.InvariantCulture, "Exiting {0}.Execute()", this.ChildClassName));
}
}
并将您的代码添加到try
块。
IServiceProvider
为您提供IPluginExecutionContext
和IOrganizationServiceFactory
实例,您需要a.获取插件执行的上下文,b.访问组织服务接口。
