&NBSP; &NBSP; &NBSP; &NBSP; &NBSP; {

&NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP;

&NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; Outlook.AppointmentItem newAppointment =

&NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; （Outlook.AppointmentItem）

&NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; this.Application.CreateItem（Outlook.OlItemType.olAppointmentItem）;

&NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; newAppointment.Start = DateTime.Now.AddHours（2）;

&NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; newAppointment.End = DateTime.Now.AddHours（3）;

&NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; newAppointment.Location =" ConferenceRoom＃2345";

&NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; newAppointment.Body =

&NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; sentInvite = sentTo.Add（"Holly Holt"）;

&NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; sentInvite.Type =（int）Outlook.OlMeetingRecipientType

&NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; .olRequired;

&NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; sentInvite = sentTo.Add（" David Junca"）;

&NBSP; &NBSP; &NBSP; &NBSP; &NBSP; }¥b $ b &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; catch（例外情况）

&NBSP; &NBSP; &NBSP; &NBSP; &NBSP; {

&NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; MessageBox.Show（"发生以下错误：" + ex.Message）;

&NBSP; &NBSP; &NBSP; &NBSP; &NBSP; }¥b $ b &NBSP; &NBSP; &NBSP; }

以下错误即将发生

'WindowsFormsApplication1.Form1'不包含'Application'的定义并且没有扩展方法'Application'接受类型为'WindowsFormsApplication1.Form1'的第一个参数'（您是否缺少using指令或汇编引用？）

请帮助
