遞歸實現遍歷文件夾的兩種方法

在網上，遍歷文件夾的算法大多是用遞歸思想實現的 ，我查了一下資料，結合應用實際，總結了兩個方法。

方法一、

 

public void FindAllFiles(string path)
        ...{
            if (Directory.Exists(path)==true )
            ...{

               DirectoryInfo[] ChildDirectory;//子目錄集
                FileInfo[] NewFileInfo;//當前所有文件
                DirectoryInfo FatherDirectory = new DirectoryInfo(path); //當前目錄
                ChildDirectory = FatherDirectory.GetDirectories("*.*"); //得到子目錄集

                NewFileInfo = FatherDirectory.GetFiles();//得到文件集，可以進行操作
               foreach (FileInfo file in NewFileInfo)
               ...{
                  
                       listBox1.Items.Add((Object)file.FullName);
                  
              }
                foreach (DirectoryInfo dirInfo in ChildDirectory)
               ...{
                   FindAllFiles(dirInfo.FullName);
               }
          }
           
        }

 

方法二、

 

private void FindAllFiles(string folderpath)
        ...{

            if (Directory.Exists(folderpath) == true)
            ...{

                foreach (string str in Directory.GetFiles(folderpath))
                ...{
                    
                        listBox1.Items.Add((Object)str.ToString());

                }
                foreach (string strfolder in Directory.GetDirectories(folderpath))
                ...{
                    FindAllFiles(strfolder);
                }

            }

        }
