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。

源码:

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data; using System.Drawing;

using System.Linq; using System.Text;

using System.Threading.Tasks;

using System.Windows.Forms;

using System.IO;

namespace WindowsFormsApplication47

{     public partial class Form1 : Form    

{         public Form1()       

  {             InitializeComponent();         }

        private void button2_Click(object sender, EventArgs e)    

     {             FolderBrowserDialog p_folderbrowserdialog = new FolderBrowserDialog();     

        if(p_folderbrowserdialog .ShowDialog ()==DialogResult.OK )           

  {                 File.Create(p_folderbrowserdialog.SelectedPath + "\" + Guid.NewGuid().ToString() + ".txt");             }         }

        private void button1_Click(object sender, EventArgs e)      

   {             FolderBrowserDialog p_folderbrowserdialog = new FolderBrowserDialog();     

        if(p_folderbrowserdialog .ShowDialog ()==DialogResult.OK )           

  {                 Directory.CreateDirectory(p_folderbrowserdialog.SelectedPath + "\" + Guid.NewGuid().ToString());             }         }     } }

歡迎分享,謝謝!
