注解
在启动进程之前, FileName 必须至少设置 属性。 文件名是任何应用程序或文档。 文档定义为具有与之关联的打开或默认操作的任何文件类型。 可以使用“ 文件夹选项 ”对话框(可通过操作系统使用)查看计算机的已注册文件类型及其关联的应用程序。 “ 高级 ”按钮将打开一个对话框,显示是否存在与特定已注册文件类型关联的打开操作。
可用的文件类型集在一定程度上取决于 属性的值 UseShellExecute 。 如果 UseShellExecute 为 true
,则可以启动任何文档并使用 组件对文件执行操作, Process 例如打印。 当 为 false
时UseShellExecute,只能使用 Process 组件启动可执行文件。
可以通过将 属性设置为 FileName 位置来启动 ClickOnce 应用程序 (例如,最初安装应用程序的 Web 地址) 。 不要通过指定 ClickOnce 应用程序在硬盘上的安装位置来启动该应用程序。
