在datagridview中顯示文件和子文件夾的列表？

Question

我有一個應用程序，它顯示目錄中的文件列表，並會彈出一條消息，只要有一個文件超過了一定的文件限制。但不知何故，我不能讓它顯示該目錄內的子文件夾。我怎樣才能做到這一點。這裏是我的代碼：

public partial class Form1 : Form 
{ private Timer timer; 
    private int count; 
    DataTable dt = new DataTable(); 
    DataRow dr; 
    String[] s1; 
    public Form1() 
    { 
     InitializeComponent(); 
    } 

    private void Form1_Load(object sender, EventArgs e) 
    { 
     count = 0; 
     timer = new Timer(); 
     timer.Interval = 1000; 
     timer.Tick += new EventHandler(timer1_Tick); 
     timer.Start(); 
     //Initialize Directory path 
     s1 = Directory.GetFiles(@"C:\Documents and Settings\Administrator\Desktop\FILE"); 
     //File Name, File Type, File size, create date 
     for (int i = 0; i <= s1.Length - 1; i++) 
     { 
      if (i == 0) 
      { 
       //Add Data Grid Columns with name 
       dt.Columns.Add("File_Name"); 
       dt.Columns.Add("File_Type"); 
       dt.Columns.Add("File_Size"); 
       dt.Columns.Add("Create_Date"); 
      } 
      //Get each file information 
      FileInfo f = new FileInfo(s1[i]); 
      FileSystemInfo f1 = new FileInfo(s1[i]); 
      dr = dt.NewRow(); 
      //Get File name of each file name 
      dr["File_Name"] = f1.Name; 
      //Get File Type/Extension of each file 
      dr["File_Type"] = f1.Extension; 
      //Get File Size of each file in KB format 
      dr["File_Size"] = (f.Length/1024).ToString(); 
      //Get file Create Date and Time 
      dr["Create_Date"] = f1.CreationTime.Date.ToString("dd/MM/yyyy"); 
      //Insert collected file details in Datatable 
      dt.Rows.Add(dr); 


      if ((f.Length/1024) > 5000) 
      { 
       MessageBox.Show("" + f1.Name + " had reach its size limit."); 
      } 
      else 
      { } 

     } 
     if (dt.Rows.Count > 0) 
     { 
      //Finally Add DataTable into DataGridView 
      dataGridView1.DataSource = dt; 
     } 
    } 

     private void timer1_Tick(object sender, EventArgs e) 
     { 
      count++; 
      if (count == 60) 
      { 
       count = 0; 
       timer.Stop(); 
       Application.Restart(); 
      } 
     } 
     public string secondsToTime(int seconds) 
     { 
      int minutes = 0; 
      int hours = 0; 

      while (seconds >= 60) 
      { 
       minutes += 1; 
       seconds -= 60; 
      } 
      while (minutes >= 60) 
      { 
       hours += 1; 
       minutes -= 60; 
      } 

      string strHours = hours.ToString(); 
      string strMinutes = minutes.ToString(); 
      string strSeconds = seconds.ToString(); 

      if (strHours.Length < 2) 
       strHours = "0" + strHours; 
      if (strMinutes.Length < 2) 
       strMinutes = "0" + strMinutes; 
      if (strSeconds.Length < 2) 
       strSeconds = "0" + strSeconds; 

      return strHours + ":" + strMinutes + ":" + strSeconds; 
     } 
    } 

Answer 1

您可以在以下過載：

Directory.GetFiles(@"C:\Documents and Settings\Administrator\Desktop\FILE", 
        "*", 
        SearchOption.AllDirectories) 

這將查找在目錄（包括子目錄）的所有文件，匹配第二個參數傳遞的圖案，其。

此外，返回的文件名包括所有文件的完整路徑，因此您可以正確處理它們。
