asp.net将DataView转换成DataTable

这个比较简单

  /**/ /// <summary>
    /// 将DataView转换为DataTable
    /// </summary>
    /// <param name="obDataView"></param>
    /// <returns></returns>
     public  DataTable GetDataTable(DataView obDataView)
     {
        if (null == obDataView)
        {
            throw new ArgumentNullException("DataView", "Invalid DataView object specified");
        }

        DataTable obNewDt = obDataView.Table.Clone();
        int idx = 0;
        string[] strColNames = new string[obNewDt.Columns.Count];
        foreach (DataColumn col in obNewDt.Columns)
        {
            strColNames[idx++] = col.ColumnName;
        }

        IEnumerator viewEnumerator = obDataView.GetEnumerator();
        while (viewEnumerator.MoveNext())
        {
            DataRowView drv = (DataRowView)viewEnumerator.Current;
            DataRow dr = obNewDt.NewRow();
            try
            {
                foreach (string strName in strColNames)
                {
                    dr[strName] = drv[strName];
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
            obNewDt.Rows.Add(dr);
        }
        return obNewDt;
    }
