ExplainText property: PSMessage class
Description
This property returns the explanation text (as a string) for the error message associated with the PSMessage object. You can use this property in conjunction with the MessageNumber property (which contains the error message number) and the MessageSetNumber property (which contains the error message set number.)
Note:
ExplainText should be accessed only when necessary because it requires a second database read or application server round trip.
This property is read-only.
