C#遍历整个文件夹及子目录的文件代码,.Net技术文章,Asp.net系列教程,Asp.n...

public void ListFiles(FileSystemInfo info)

{

if (!info.Exists) return;

DirectoryInfo dir = info as DirectoryInfo;

//不是目录

if (dir == null) return;

FileSystemInfo[] files = dir.GetFileSystemInfos();

for (int i = 0; i < files.Length; i++)

{

FileInfo file = files[i] as FileInfo;

//是文件

if (file != null)

{

//Console.WriteLine(file.FullName + "\t " + file.Length);

if (file.FullName.Substring(file.FullName.LastIndexOf(".")) == ".jpg")　

//此处为显示JPG格式，不加IF可遍历所有格式的文件

{

this.list1.Items.Add(file);

//MessageBox.Show(file.FullName.Substring(file.FullName.LastIndexOf(".")));

}

}

//对于子目录，进行递归调用

else

{

ListFiles(files[i]);

}

}

调用：

string dir；

ListFiles（new DirectoryInfo（dir））；
