Framework1.1 DataView 转DataTable

因为Framework2.0开始DataView 有toTable()方法，可以直接转。但vs2003还是Framework1.1 没有这个方法。

所以要手动转，方法如下：

public static DataTable CreateTable(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;
        }
