dynamics-crm-2011 - 使用 context.InputParameters ["Target"]

Question

我正在为 Dynamics CRM 2011 创建一个插件，以便在验证潜在客户时执行。我用这个代码

IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
IOrganizationServiceFactory factory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
IOrganizationService service = factory.CreateOrganizationService(null);
Entity curEntity = (Entity)context.InputParameters["Target"];

但是当我得到 context.InputParameters["Target"] 时，它说找不到该 key 。在确定潜在客户资格时，如何获得牵头实体？

Answer 1

如果您的插件是在 QualifyLead 消息上执行的(Lead 作为主要实体)，您可以通过这种方式获取对 lead 的引用:

public void Execute(IServiceProvider serviceProvider)
{
    ITracingService tracingService = (ITracingService)serviceProvider.GetService(typeof(ITracingService));
    IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
    if (context.InputParameters.Contains("LeadId") && context.InputParameters["LeadId"] is EntityReference)
    {
        EntityReference leadReference = (EntityReference)context.InputParameters["LeadId"];
        Guid leadId = leadReference.Id;
        // rest of your code

基本上这条消息不包含Target参数，而是包含LeadId参数。
