因?yàn)镕ramework2.0開(kāi)始DataView 有toTable()方法，可以直接轉(zhuǎn)。但vs2003還是Framework1.1 沒(méi)有這個(gè)方法。

所以要手動(dòng)轉(zhuǎn)，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;
??????? }?
