遍曆檔案夾並判斷檔案格式

 

f盤下有檔案夾a,a檔案夾下面有2012-2-2-22-22檔案夾，2012-2-2-22-22檔案夾下面有3.affix1和3.his1

 

protected void button1_Click(object sender, EventArgs e)
        {
            string name="";
            DirectoryInfo theFolder = new DirectoryInfo(@"F:\a\");
            DirectoryInfo[] dirInfo = theFolder.GetDirectories();
            //遍曆檔案夾
            foreach (DirectoryInfo NextFolder in dirInfo)
            {
                //遍曆檔案夾
                //this.listBox2.Items.Add(NextFolder.Name);
                // 遍曆檔案夾下檔案
                        FileInfo[] fileInfo = NextFolder.GetFiles();
                        foreach (FileInfo NextFile in fileInfo)  //遍曆檔案
                        {

 

                            name = NextFile.Name.ToString();
                            int i = name.LastIndexOf(".");
                           string ext = name.Substring(i);
                            string[] allowext = { ".his1", ".affix1" };
                            for (int a = 0; a < allowext.Length; a++)
                            {
                                if (ext == allowext[a])
                                {
                                    //  this.listBox2.Items.Add(NextFile.Name);
                                    this.listBox2.Items.Add(name);
                                }
                            }
                        }
                  
             
            }
