通过字典给类的实体属性赋值生成url字符串

private static Dictionary<string, string> SortedToDictionary(SortedDictionary<string, string> dicArrayPre, params string[] paras)
{

foreach (KeyValuePair<string, string> temp in dicArrayPre)
if (!paras.Contains(temp.Key) && !string.IsNullOrEmpty(temp.Value))
dict.Add(temp.Key, temp.Value);
return dict;
}
