無法將類型爲“System.Object[*]”的對象強制轉換爲類型“System.Object[]”的解決方法

 

        /// <summary>
        /// 將下標爲1的數組轉換爲.Net的數組
        /// </summary>
        /// <param name="arr"></param>
        /// <returns></returns>
        private object[] ConvertArray(Array arr)
        {
            int lb = arr.GetLowerBound(0);
            var ret = new object[arr.GetUpperBound(0) - lb + 1];
            for (int ix = 0; ix < ret.Length; ++ix)
            {
                ret[ix] = arr.GetValue(ix + lb);
            }
            return ret;
        }

object[] os= ConvertArray(ft.Criteria1 as Array);
foreach (object o in os)
{
    MessageBox.Show(o.ToString());
}

將第二段代碼中ft.Criteria1改爲對應的下標爲1的數組
