如何在VBA中安排邮件发送到特定时间

生成邮件的代码

Set olApp = CreateObject("Outlook.application")
Set olItem = olApp.CreateItem(0)
olItem.display
olItem.To = "bhagyashri.kulkarni@mindtree.com"
olItem.Subject = "Auto Generated - Consolidated Task Tracking Report"
olItem.htmlbody = Join(aBody, vbNewLine)
olItem.Attachments.Add outputFileName
olItem.display

DeferredDeliveryTime 有用吗？如何使用它 ？

public override bool Equals(object obj)
{
    var par = obj as Parameter;
    if (ParameterName == par.ParameterName )  /* <=throws error at this code */
        return true;
    else
        return false;

}

我在运行该代码时遇到此错误: Object reference not set to an instance of an object

如何删除c#中的错误？
