public partial class ViewIcon : System.Web.UI.Page
{
JArray ja = new JArray(); //定义一个数组
public string info = string .Empty;
protected void Page_Load( object sender, EventArgs e)
{
var path1 = System.AppDomain.CurrentDomain.BaseDirectory; //获取程序集目录
string path = Path.Combine(path1, "Image" , "menu" ); //Path.Combine 将3个字符串组合成路径
var images = Directory.GetFiles(path, "." , SearchOption.AllDirectories).Where(s => s.EndsWith( ".png" ) || s.EndsWith( ".jpg" ) || s.EndsWith( ".gif" ));
//images = Directory.GetFiles(path, "*.png|*.jpg", SearchOption.AllDirectories);
//Directory.GetFiles 返回指定目录的文件路径 SearchOption.AllDirectories 指定搜索当前目录及子目录
//遍历string 型 images数组
foreach (var i in images){
var str = i.Replace(path1, "" ); //获取相对路径
var path2 = str.Replace( "\\" , "/" );将字符“\\”转换为“/”
ja.Add(path2);
}
info = Newtonsoft.Json.JsonConvert.SerializeObject(ja); //序列化为String
}

效果图如下:
下面给大家介绍下C# 遍历文件夹下所有子文件夹中的文件,得到文件名
假设a文件夹在F盘下,代码如下。将文件名输出到一个ListBox中
