openFileDialog的Filter属性设置
OpenFileDialog对话框的Filter属性说明： 首先说明一个示例，分析一下Filter属性的构成：“ Excel文件|*.xls ”，前面的“Excel文件”成为标签，是一个可读的字符串 试用*表示匹配文件名的字符，使用“.后缀”匹配文件的后缀名，通过连接后缀（试用;号将需要的后缀分开）表示同时筛选所有的符合后缀的文件，通过“|”连接不同的筛选器表示通过用户选择后缀名称来进行文件筛选 OpenFileDialog openFile=new OpenFileDialog(); openFile.Filter="(*.jpg,*.png,*.jpeg,*.bmp,*.gif)|*.jgp;*.png;*.jpeg
