C# DataSet转化为List<string[]>

DataTable dt = ds.Tables[0];List<string[]> list = new List<string[]>();foreach (DataRow r in dt.Rows){    int colCount = r.ItemArray.Count();    string[] items = new string[colCount];    for (int i = 0; i < colCount; i++)    {        items[i] = Convert.ToString(r.ItemArray[i]);    }    list.Add(items);}
