我想创建一个插件,根据可以在电子邮件正文中找到的特定格式创建记录。例如:
PO / Dustine / Tolete / 8:45 PM /样品位置/样品desc
到目前为止,我有这段代码:
using System;
using System.Diagnostics;
using System.Linq;
using System.ServiceModel;
using Microsoft.Xrm.Sdk;
using Xrm;
public class Plugin : IPlugin
{
public void Execute(IServiceProvider serviceProvider)
{
IPluginExecutionContext context = (IPluginExecutionContext)
serviceProvider.GetService(typeof(IPluginExecutionContext));
Entity entity;
// Check if the input parameters property bag contains a target
// of the create operation and that target is of type Entity.
if (context.InputParameters.Contains("Target") &&
context.InputParameters["Target"] is Entity)
{
// Obtain the target business entity from the input parameters.
entity = (Entity)context.InputParameters["Target"];
// Verify that the entity represents a contact.
if (entity.LogicalName != "email") { return; }
}
else
{
return;
}
try
{
IOrganizationServiceFactory serviceFactory =
(IOrganizationServiceFactory)serviceProvider.GetService(
typeof(IOrganizationServiceFactory));
IOrganizationService service =
serviceFactory.CreateOrganizationService(context.UserId);
var id = (Guid)context.OutputParameters["id"];
AddNewServiceRequest(service, id);
}
catch (FaultException<OrganizationServiceFault> ex)
{
throw new InvalidPluginExecutionException(
"An error occurred in the plug-in.", ex);
}
}
private static void AddNewServiceRequest(IOrganizationService service, Guid id)
{
using (var crm = new XrmServiceContext(service))
{
var email = crm.EmailSet.Where(c => c.ActivityId == id).First();
string[] noteText = email.Description.ToString().Split('/');
foreach(string text in noteText){
Console.WriteLine(text);
}
Entity peaceAndOrder = new Entity("msa_noisecomplaintrequest");
peaceAndOrder["msa_firstname"] = noteText[1];
peaceAndOrder["msa_lastname"] = noteText[2];
peaceAndOrder["msa_incidenttime"] = noteText[3];
peaceAndOrder["msa_location"] = noteText[4];
peaceAndOrder["msa_description"] = noteText[5];
service.Create(peaceAndOrder);
}
}
}
但每次触发事件时,都会发生错误。我做错了什么?
答案 0 :(得分:1)
您正在使用context.OutputParameters来获取电子邮件ID。我假设你的插件是在post创建事件上注册的。 确保步骤确实已正确注册(即在post事件上运行),并且电子邮件实体上没有运行其他插件。
如果你确实有其他插件在电子邮件上运行(例如预事件插件),你必须用适当的条件包装你的代码,确保只在post创建事件上运行,即
if (context.Stage == 40 /*Post Operation*/)
{
// Your code here …
}
使用检查正确消息名称的条件包装代码也是一种好习惯,例如
if (context.MessageName == "CREATE")
{
// Your code here …
}
作为旁注,您将AddNewServiceRequest定义为静态。插件由CRM缓存,因此它们在某种意义上是静态的。您不需要声明静态成员 在您的代码中,除非您打算在插件之间或在对象内声明静态成员时共享数据。
最后,启用平台跟踪或调试以瞥见真正导致此问题的原因。
