本文介绍了如何使用C#语言编写代码，实现遍历指定目录下所有文件，并筛选出特定类型的文件。同时，通过正则表达式过滤掉包含中文字符的代码行，以确保只保留纯英文内容。

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））；

过滤项目中含有中文的地方除注释以外
