EWS API 2.0 Read Calendar information-read content considerations

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

Use the demo account to read the calendar information, note the contents of the calendar reading (Body) read. The code is as follows: (with EWS API version 2.0)

1. The following properties must be set before reading the content: Otherwise you will be prompted: must load or assign this property before you can read its value Body

As follows:

Thought to be set to read content, otherwise you will be prompted: You must load or assign the property before you can read its value  Body

    New PropertySet (Basepropertyset.firstclassproperties, appointmentschema.recurrence);

     in Findresults Select item, Detailedpropertyset);

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

After setting up normal.

2. If you want to read plain text of the content, the current version within Exchange server2010 supports reading content with HTML. The calling code is as follows:

If the text is not empty

                        if (item. TextBody = null)

                        {

                            TextBody txtbody = Item. TextBody;

                            //

                            Info. BodyText = Txtbody.text;

                        }

The following error occurred after the call:

therefore, only regular expressions can be used to get the text content.  

The correct code is included:
