Question

ASP.NET 中 SqlParameter 与 Hashtable

private static Hashtable parmCache = Hashtable.Synchronized(new Hashtable());        public static SqlParameter[] GetCachedParameters(string cacheKey) {            SqlParameter[] cachedParms = (SqlParameter[])parmCache[cacheKey];            if (cachedParms == null)                return null;            SqlParameter[] clonedParms = new SqlParameter[cachedParms.Length];            for (int i = 0, j = cachedParms.Length; i < j; i++)                clonedParms[i] = (SqlParameter)((ICloneable)cachedParms[i]).Clone();            return clonedParms;        }请问各位上面的代码是什么意思，也就是加粗的那些语句的含意，看了半天我也没看明白，请具体点，谢谢。
