C#遍历文件夹

var files = Directory.GetFiles(@"C:\", "*.*",SearchOption.AllDirectories); // 遍历所有文件
var dirs= Directory.GetDirectories(@"C:\", "*", SearchOption.AllDirectories); //遍历所有文件夹

DirectoryInfo TheFolder = new DirectoryInfo(path);
if (!TheFolder.Exists)
    return;
//遍历文件
foreach (FileInfo NextFile in TheFolder.GetFiles())
{
    // 获取文件完整路径
    string heatmappath = NextFile.FullName;
}
