页面之间dataset数据传递方法

来源：http://blog.csdn.net/bayaci/archive/2007/12/19/1953842.aspx

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();




/**///// Display the content.


//Console.WriteLine(responseFromServer);




/**///// Cleanup the streams and the response.






////Response.Write(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;
