【CSharp】 C#读取所有目录

作者:http://blog.csdn.net/Come_On_steven/ / 发布于2011/1/3/ 549

本来还可以读出所有目录的名字，但是考虑到文件名中包含完整文件路径，故意义不大，就不用读出目录名功能。主要功能： 1.读取指定目录下含子目录中所有文件。 2.计算文件大小 3.文件含完整路径 4.列表显示到ListBox控件 5.列表写入指定Txt文本文件

{ 

 string path = @"<a href="file://\\192.168.1.88\movie\">\\192.168.1.88\movie\</a>音乐综艺"; //目录名 也可以用相当路径 
 string filter = "*.*"; //文件类型 
 int m_numFiles = 0; //文件总数 
 ArrayList m_pathList = new ArrayList();//包含所有文件路径的数组 
 string[] files; //所有文件名 


 protected void Page_Load(object sender, EventArgs e) 
 { 

 } 
 
 private string[] CreatePathList() 
 { 
 if (m_numFiles <= 0) 
 { 
 return null; 
 } 

 string[] str = new string[m_numFiles]; 
 int index = 0; 

 try 
 { 
 IEnumerator pathIter = m_pathList.GetEnumerator(); 
 while (pathIter.MoveNext()) 
 { 
 string[] ar = (string[])(pathIter.Current); 
 IEnumerator fileIter = ar.GetEnumerator(); 
 while (fileIter.MoveNext()) 
 { 
 str[index] = (string)(fileIter.Current); 
 ++index; 
 } 
 } 
 } 
 catch (Exception e) 
 { 
 Console.Write(e.ToString()); 
 return null; 
 } 

 return str; 

 } 

 private void ParseDirectory(string path, string p) 
 { 
 string[] dirs = Directory.GetDirectories(path);//得到子目录 
 IEnumerator iter = dirs.GetEnumerator(); 
 while (iter.MoveNext()) 
 { 
 string str = (string)(iter.Current); 
 ParseDirectory(str, filter); 
 } 
 string[] files = Directory.GetFiles(path, filter); 
 if (files.Length > 0) 
 { 
 foreach (string filename in files) 
 { 
 
 FileInfo inf=new FileInfo(filename); 
 float value = inf.Length / 1024 /1024; 
 m_numFiles += files.Length; 
 m_pathList.Add(files); 
 ListBox1.Items.Add(filename); 
 ListBox1.Items.Add("文件大小:"+value.ToString()+"M"); 
 } 
 } 

 } 
 
 protected void BtGetFileList_Click(object sender, EventArgs e) 
 { 
 ParseDirectory(path, "*.*"); 
 files = CreatePathList(); //生成文件名数组 
 //ListBox1.Items.Add(files.ToString()); 
 if (files == null) 
 { 
 throw new Exception(String.Concat("No file found in ", path)); 
 } 
 } 
 protected void BtInsrtTxt_Click(object sender, EventArgs e) 
 { 
 if (File.Exists("c:\\test.txt") == true) 
 { 
 try 
 { 
 //label2.Text = "OK"; 
 //File.Delete("c:\\test.txt"); 
 //File.Create("test.txt"); 
 StreamWriter sw = new StreamWriter("c:\\test.txt", true); 
 for (int i = 0; i < ListBox1.Items.Count; i++) 
 { 
 //写入TXT文件 
 sw.Write(ListBox1.Items[i].ToString() + "\r\n"); 
 } 
 sw.Close(); 
 
 
 } 
 catch (Exception err) 
 { 
 Console.WriteLine(err.ToString());

 } 
 else

 } 
 } 
}

试试其它关键字

　读取目录　

同语言下

可能有用的
