まず、msdn Uriクラスを見てみましょう.Uriクラスはこの文章とは関係ありません.ただ、検索を便利にするためです.
/// <summary>
/// url ？ ， Dictionary<key, value>
/// </summary>

else

Dictionary<string, string> dt = new Dictionary<string, string>();
string strRight = url.Substring(intPos + 1);
string[] arrPram = StringSplit(strRight, "&");
for (int i = 0; i < arrPram.Length; i++)
