system.io.file创建
在实际开发中,如果用的文件名不能确定位置。或名字。可以使用GUID类来命名函数。Guid 结构标识全局唯一标示符。其NewGuid结构可以初始化一个新历。该方法语法格式如下:
public static Guid NewGuid();
return: 初始化后的实例。

{ FolderBrowserDialog p_folderbrowserdialog = new FolderBrowserDialog();
if(p_folderbrowserdialog .ShowDialog ()==DialogResult.OK )
{ File.Create(p_folderbrowserdialog.SelectedPath + "\\" + Guid.NewGuid().ToString() + ".txt"); } }

if(p_folderbrowserdialog .ShowDialog ()==DialogResult.OK )
{ Directory.CreateDirectory(p_folderbrowserdialog.SelectedPath + "\\" + Guid.NewGuid().ToString()); } } } }
