EWS API 2.0读取日历信息-读取内容注意事项
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
如下图：
//*************************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 BodyPropertySet 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：
