u 實驗步驟(2):
在類Form3裡添加二個靜态字段directory_path、directory_otherpath,都為string類型,分别代表工作目錄路徑和其他目錄路徑;輕按兩下“建立目錄”、“删除目錄”、“移動目錄”、“目錄建立時間”、“傳回指定目錄檔案”,在click事件處理方法裡分别添加代碼如下:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.IO;
namespace FileOptionApplication
{
public partial class Form3 : Form
{
public Form3()
{
InitializeComponent();
}
private static string directory_path = "c:\\qs250";
private static string directory_otherpath = "c:\\qqqq";
/// <summary>
/// 删除目錄滑鼠單擊事件
/// </summary>
private void button1_Click(object sender, EventArgs e)
try
{
Directory.CreateDirectory(directory_path);
button2.Enabled = true;
button1.Enabled = false;
button3.Enabled = true;
button4.Enabled = true;
button5.Enabled = true;
MessageBox.Show("檔案夾成功建立。", "警報");
}
catch (Exception mm)
MessageBox.Show("磁盤操作錯誤,原因:" + Convert.ToString(mm), "警報");
private void button2_Click(object sender, EventArgs e)
Directory.Delete(directory_path);
button2.Enabled = false;
button1.Enabled = true;
button3.Enabled = false;
button4.Enabled = false;
button5.Enabled = false;
MessageBox.Show("檔案夾删除建立。", "警報");
/// 移動目錄滑鼠單擊事件
private void button3_Click(object sender, EventArgs e)
Directory.Move(directory_path, directory_otherpath);
MessageBox.Show("檔案夾移動成功。", "警報");
//舉例來講,如果您嘗試将c:\mydir 移到c:\public,并且c:\public 已存在,
//則此方法引發IOException。您必須将“c:\\public\\mydir”指定為destDirName 參數,或者指定新目錄名,例如“c:\\newdir”。
/// 目錄建立時間滑鼠單擊事件
private void button4_Click(object sender, EventArgs e)
MessageBox.Show(string.Format("{0:G}",Directory.GetCreationTime(directory_path)), "提示");
//擷取時間格式參見DateTimeFormatInfo
/// 傳回指定目錄檔案滑鼠單擊事件
private void button5_Click(object sender, EventArgs e)
string[] fileEntries = Directory.GetFiles(directory_path);
if (fileEntries.Length != 0)
{
foreach (string s in fileEntries)
{
if (File.Exists(s))
{
MessageBox.Show("内有檔案資訊:" + s, "提示");
}
}
}
else
MessageBox.Show("空檔案夾", "提示");
//擷取時間格式參見DateTimeFormatInfo
}
}
