  2. 在"文件"菜单上,指向"新建",然后单击"Project"

  3. 在" Visual C#项目类型"列表中 ,单击" 控制台应用程序"默认情况下,将创建 Class1.cs 文件。注意 在 Microsoft Visual C# 2005 中,单击"Visual C#项目类型"列表中的" visual C#" 。 默认情况下,将创建 Program.cs。

  4. 添加对 Microsoft Outlook 10.0 对象库的引用。 为此,请执行以下步骤:

    1. 在"Project"菜单上,单击"添加引用"

    2. 单击"COM"选项卡,找到"Microsoft Outlook 10.0 对象库",然后单击"选择"注意 在 Microsoft Visual C# 2005 中。 不需要单击"选择 "

    3. 在" 添加引用" 对话框中,单击"确定 "

    4. 如果系统提示为所选库生成包装器,请单击"是 "

  5. 在代码窗口中,将代码替换为以下内容:

    using System;using System.Reflection;     // to use Missing.Valuenamespace FilterAppointments{   /// <summary>   /// Summary description for Class1.   /// </summary>   class Class1   {      /// <summary>      /// The main entry point for the application.      /// </summary>      [STAThread]      public static int Main(string[] args)      {         try         {            // Create an Outlook application.            Outlook.Application oApp = new Outlook.Application();            // Get the Mapi NameSpace and the Logon.            Outlook.NameSpace oNS = (Outlook.NameSpace)oApp.GetNamespace("mapi");            // Log on using dialog to choose a profile.            oNS.Logon(Missing.Value, Missing.Value, true, true);             // Alternate Logon using specific profile            // TODO: Change the profile name where it is appropriate.            //oNS.Logon("YourValidProfile", Missing.Value, false, true);             // Get the Calendar folder.            Outlook.MAPIFolder oCalendar = oNS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderCalendar);            // Get the Items collection in the folder.            Outlook.Items  oItems = (Outlook.Items)oCalendar.Items;            Console.WriteLine("Total Items (unrestricted): " + oItems.Count);            //Include all occurrences of recurring items, and then sort them.            oItems.Sort ("[Start]", false);            oItems.IncludeRecurrences = true;            // Define the string for the search criteria.            String sCriteria;            // Set the criteria for the Date fields.            sCriteria = "[Start] <= '09/01/2002 08:00 AM' and [End] >= '2/15/2002 08:00 PM'";            // Set the criteria for a string field.            // sCriteria = "[Subject] = 'Weekly recurring meeting'";            // Set the criteria for a numeric field.            // Look for meetings that have not been responded to.            // sCriteria = "[ResponseStatus] = " + (Int32)Outlook.OlResponseStatus.olResponseNotResponded)            // Use the Restrict method to reduce the number of items to process.            Outlook.Items oRestrictedItems = oItems.Restrict(sCriteria);            oRestrictedItems.Sort ("[Start]", false);            oRestrictedItems.IncludeRecurrences = true;            Console.WriteLine("Total Items Unrestricted : " + oRestrictedItems.Count);            Outlook.AppointmentItem oAppointment;            //Get each item until item is null.            Outlook.AppointmentItem oAppt;            oAppt = (Outlook.AppointmentItem)oRestrictedItems.GetFirst();            while (oAppt != null)            {               // Console.WriteLine(i.ToString());                Console.WriteLine("  Subject: " + oAppt.Subject.ToString());                Console.WriteLine("  Start time: " + oAppt.Start.ToString());                Console.WriteLine("  End time: " + oAppt.End.ToString());                Console.WriteLine("  Occurrences: " + oAppt.RecurrenceState.ToString());                Console.WriteLine("\n\n");                oAppt = (Outlook.AppointmentItem)oRestrictedItems.GetNext();            }            // Use the Find method to get single match.            sCriteria = "[Start] >= '09/30/2001'";             Console.WriteLine("Criteria: " + sCriteria.ToString());            oAppointment = (Outlook.AppointmentItem)oItems.Find(sCriteria);            Console.WriteLine("Used Find with Date fields");            if (oAppointment is Outlook.AppointmentItem)                Console.WriteLine("Found -> " + oAppointment.Subject.ToString());            else               Console.WriteLine("No object found");            // Log off            oNS.Logoff();            // Clean up            oAppointment = null;            oRestrictedItems = null;            oItems = null;            oCalendar = null;            oNS = null;            oApp = null;         }            //Simple error handling         catch (Exception e)         {            Console.WriteLine("{0} Exception caught.", e);         }           //Default return value         return 0;      }   }}
  6. 在代码中搜索 TODO 文本字符串,然后修改环境的代码。

  7. 按 F5 键生成 和 以运行程序。
