The ImportFromMsProjectXml (string fileName, [bool roundToDurationUnit = True]) helps in importing Microsoft Project's xml file. It takes the parameter fileName, which is the File name to import, and roundToDurationUnit, which Indicates whether the Start and Finish will be rounded according to the C1.Win.C1GanttView.DurationUnits enumeration.
