如何添加多个扩展：var set = new HashSet<string> { "*.exe", "*.bat", "*.reg" };在GetFiles()？

foreach (var Search in new DirectoryInfo(@"E:\Loader\").GetFiles("*.exe"))// <- Сюда

    可以用Linq完成

    string[] extensions = new string[] {".gif",".jpg"};
dir.GetFiles().Where(f => extensions.Contains(f.Extension))

  2. string[] extensions = new string[] { ".txt", ".sql" }; 
var array_files_all = Directory.GetFiles(@"sql\", "*").Where(f => extensions.Any(w => f.Contains(w))).Select(a => a.ToString());
string[] array_files = new string[array_files_all.Count()];//выбор всех файлов нужной кодировки
int n = 0;
foreach (var file in array_files_all)
{
    array_files[n] = file;
    n++;
}
