答案

参考答案:C

解析:文件对话框分为两种:即打开对话框和保存对话框,所以选项A)正确;通用对话框的Name属性的默认值为CommonDialogX ,此外,每种对话框都有自己的默认标题,所以选项B)正确;打开文件对话框可以让用户指定一个文件,由程序使用,而用保存文件对话框可 以指定一个文件,并以这个文件名保存当前文件,所以选项 C)正确;除DefaultEXT、DialogTide属性是打开和保存对话框共有的,还有 FileName、FileTitle、Filter、FilterIndex、Flags、InitDir、MaxFileSize、CancelError、HelpCommand、HelPContext和HelpFile属性, 都是它们共有的,所以选项D)不正确。
