WriteXml的用法

可以使用WriteXml将SQL中的数据，写到Xml文件中。使用ds.WriteXml或者dt.WriteXml都可以。

下面是代码例子：

    private void BindToGridView1(string StrPositionId)
    {
        //string sqlString = string.Empty;
        List<SalesUserInfo> SalesList;
        SalesList = new List<SalesUserInfo>();

        string strHeaderPostnID = "1-258KID";

        clsUser user = new clsUser();
        List<UserInfo> TeamUser = new List<UserInfo>();
        TeamUser = user.AuditTeamMember(strHeaderPostnID);

        int count = 1;

        for (int i = 0; i < TeamUser.Count; i++)
        {
            SalesUserInfo eSales = new SalesUserInfo();

            eSales.LoginName = TeamUser[i].LoginName;
            eSales.AliasName = TeamUser[i].AliasName;
            eSales.PostnID = TeamUser[i].PostnID;

            eSales.SortNo = string.Format("IAG{0:0#}", count);
            eSales.Region = "华东PA";
            eSales.Active = "Y";
            eSales.ActiveForPAC = "Y";
            eSales.ActiveForWOP = "Y";

            count++;
            SalesList.Add(eSales);
        }

        DataTable resultDataTable = new DataTable("IAG");
        resultDataTable.Columns.Add("SortNo", Type.GetType("System.String"));
        resultDataTable.Columns.Add("Region", Type.GetType("System.String"));
        resultDataTable.Columns.Add("AliasName", Type.GetType("System.String"));
        resultDataTable.Columns.Add("LoginName", Type.GetType("System.String"));
        resultDataTable.Columns.Add("PostnID", Type.GetType("System.String"));
        resultDataTable.Columns.Add("Active", Type.GetType("System.String"));
        resultDataTable.Columns.Add("ActiveForPAC", Type.GetType("System.String"));
        resultDataTable.Columns.Add("ActiveForWOP", Type.GetType("System.String"));

        for (int i = 0; i < SalesList.Count; i++)
        {
            DataRow newRow = resultDataTable.NewRow();
            newRow["SortNo"] = SalesList[i].SortNo;
            newRow["Region"] = SalesList[i].Region;
            newRow["AliasName"] = SalesList[i].AliasName;
            newRow["LoginName"] = SalesList[i].LoginName;
            newRow["PostnID"] = SalesList[i].PostnID;
            newRow["Active"] = SalesList[i].Active;
            newRow["ActiveForPAC"] = SalesList[i].ActiveForPAC;
            newRow["ActiveForWOP"] = SalesList[i].ActiveForWOP;

            resultDataTable.Rows.Add(newRow);
        }

        gvPSMListInfo.DataSource = resultDataTable;
        gvPSMListInfo.DataBind();

        string xmlFile = Server.MapPath("IAGSalesList.xml");
        resultDataTable.WriteXml(xmlFile, XmlWriteMode.IgnoreSchema);
    }

生成的IAGSalesList.xml文件如下：
