        openfiledialog opd = new openfiledialog         {             filename = "x file",             defaultext = ".x",             filter = "x files (*.x)|*.x | files (*.*)|*.*",             multiselect = true         };          bool? result = opd.showdialog();          if (result == true)         {             //...         } 

you should change filter from

"x files (*.x)|*.x | files (*.*)|*.*" 

to

"x files (*.x)|*.x|all files (*.*)|*.*" 

as stated in msdn:

do not put spaces before or after vertical bars in filter string. cause incorrect behavior in filter.
