页面之间dataset数据传递方法

在网络上两个页面之间进行数据传递有很多中办法，这里我用了。net的现成方法，把表格数据传递到另外的页面。

db.table 数据 ——》dataset －－》xml－－》webrequest－－》dataset

以下是发送数据页面代码

string sql = @"select *,
DateAdd(minute,[RefreshIntervalTime],[LashRefreshTime]) VLastRefreshTime from WaitingRefresh
where getdate()<starttime and endtime<getdate()";

DataSet ds = DataRepository.Provider.ExecuteDataSet(CommandType.Text, sql);

//Response.Write(ds.Tables[0].Rows.Count.ToString());
Response.Clear();
Response.ContentType = "text/xml";
Response.Charset = "UTF-8";

ds.WriteXml(Response.OutputStream, XmlWriteMode.IgnoreSchema);

以下是获取根据上面的页面，把数据还原到dataset的过程：

WebRequest request = WebRequest.Create(url);
// If required by the server, set the credentials.
request.Credentials = CredentialCache.DefaultCredentials;
// Get the response.
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
// Display the status.
Console.WriteLine(response.StatusDescription);
// Get the stream containing content returned by the server.
Stream dataStream = response.GetResponseStream();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader(dataStream);
// Read the content.
//string responseFromServer = reader.ReadToEnd();
//Console.WriteLine(responseFromServer);

DataSet ds = new DataSet();

ds.ReadXml(reader);

// ds.WriteXml(Response.OutputStream, XmlWriteMode.IgnoreSchema);

//Response.Write(ds.Tables[0].Rows[0][0].ToString());

reader.Close();
dataStream.Close();
response.Close();

return ds;
