EWS API 2.0读取日历信息-读取内容注意事项

[from] http://www.cnblogs.com/love007/archive/2013/06/26/3156852.html

采用模拟账号的方式读取日历信息,注意下日历的内容读取(Body)读取。代码如下:(采用 EWS API 2.0版本)

1、读取内容前必须设置如下属性:否则会提示:You must load or assign this property before you can read its value  Body

如下:

 

 //*************************以为设置为读取内容,否则会提示:You must load or assign this property before you can read its value  Body

 

    PropertySet detailedPropertySet = new PropertySet(BasePropertySet.FirstClassProperties, AppointmentSchema.Recurrence);

 

    service.LoadPropertiesForItems(from Item item in findResults select item, detailedPropertySet);

 

 //******************************

 

设置后正常。

 

2、如果想读取内容的纯文本,目前Exchange server2010内的版本支持读取带HTML的内容。调用代码如下:

 

 //如果文本不为空

 

                        if (item.TextBody != null)

 

                        {

 

                            TextBody txtBody = item.TextBody;

 

                            //

 

                            info.BodyText = txtBody.Text;

 

                        }

 

 

 

调用后出现如下错误:

 

所以只能用正则表达式获取文本内容。 

 

附带正确代码:
