C#代码实现对HTTP POST参数进行排序

 1 private static string GetSortedParas(Dictionary<string, string> dic)
 2 {
 3     dic = dic.OrderBy(key => key.Key).ToDictionary(keyItem => keyItem.Key, valueItem => valueItem.Value);
 4     var sbPara = new StringBuilder(1024);
 5     foreach (var para in dic.Where(para => !para.Value.IsNullOrWhiteSpace()))
 6     {
 7         sbPara.AppendFormat("{0}={1}&", para.Key, para.Value);
 8     }
 9     return sbPara.ToString().TrimEnd('&');
