如果你想在字符串作爲數字而不是字典順序必須排序，解析他們：

var orderedFiles = Directory.EnumerateFiles(sdira, "*", SearchOption.AllDirectories) 
    .Select(x => new { file = x, nameNumber = Path.GetFileName(x).TryGetInt32() }) 
    .Where(x => x.nameNumber.HasValue) 
    .OrderBy(x => x.nameNumber.Value) 
    .Select(x => x.file); // or x.nameNumber.Value is you want the number 

這裏的解析擴展方法是LINQ查詢中使用：

public static int? TryGetInt32(this string item, IFormatProvider formatProvider = null, NumberStyles nStyles = NumberStyles.Any) 
{ 
    if (formatProvider == null) formatProvider = NumberFormatInfo.CurrentInfo; 
    int i = 0; 
    bool success = int.TryParse(item, nStyles, formatProvider, out i); 
    if (success) 
     return i; 
    else 
     return null; 
}
