如何通过插件C使用lookup CRM 365插入数据#

我查了一下“ 新建_lookuptransactionheader “在我的实体中” “。此查找链接自” 新建事务标头 “实体。如何使用c#crm插件插入数据?

public void InsertDataUsingLookup(XrmServiceContext xrm, Entity entitiy, ITracingService tracer)
{
    new_trialxrmservicetoolkit trial = new new_trialxrmservicetoolkit();
    trial.new_name = "testplugin";
    trial.new_LookupTransactionHeader = null; //this is i don't know how to get value from new_LookupTransactionHeader
    trial.new_Notes = "this is test plugin using c#";
    xrm.AddObject(trial);
    xrm.SaveChanges();
}

我更新了mycode并解决了这个问题:

public void InsertDataUsingLookup(XrmServiceContext xrm, Entity entitiy, ITracingService tracer)
    {
        new_trialxrmservicetoolkit trial = new new_trialxrmservicetoolkit();
        trial.new_name = "testplugin";
        trial.new_LookupTransactionHeader = new EntityReference("new_transactionheader", Guid.Parse("5564B5F0-0292-E711-8122-E3FE48DB937B"));
        trial.new_Notes = "this is test plugin using c#";
        xrm.AddObject(trial);
        xrm.SaveChanges();
    }
