{
List<string> photos = new List<string>();
string photoPath = MapPath("~/photos/");
string[] files = Directory.GetFiles(photoPath);
foreach (string photo in files)
{
photos.Add("~/photos/" + Path.GetFileName(photo));
}
return photos;
}

Answer 1

public List<string> GetPhotos()
{
--定义一个字符串的数组
List<string> photos = new List<string>();
--图片的虚拟路径
string photoPath = MapPath("~/photos/");
//返回指定路径中文件的名称
string[] files = Directory.GetFiles(photoPath);
//循环遍历读取
foreach (string photo in files)
{
//这些路径添加那个数组里面
photos.Add("~/photos/" + Path.GetFileName(photo));
}
将这个数组返回出去
return photos;
}
