Question

So I am building some XML using a XmlWriter and a DataSet but when it comes time to loop through each DataRow in the DataSet I can’t figure out how do reference like ‘userid’ and such that come back from the stored procedure. In page code I see them doing it as Eval('userid') or whatever which I am using the same stored procedure, but I am using it in an ASHX now… see the ‘WHAT GOES HERE??’ in the code below…

DataSet getData; getData = SqlHelper.ExecuteDataset(ConfigurationManager.ConnectionStrings['connstr'].ConnectionString, CommandType.StoredProcedure, 'Course_NewReportGet_Get_Sav', objPAra)  //COUNT NUMBER OF RESULTS FOR COUNT ATTRIBUTE (must add!)  XmlWriterSettings settings = new XmlWriterSettings(); settings.Indent = true; settings.IndentChars = ('    '); using(XmlWriter writer = XmlWriter.Create('data.xml', settings)) {     writer.WriteStartElement('changes');     writer.WriteAttributeString('clientname', foundCompany.CompanyName);     writer.WriteAttributeString('clientid', foundCompany.Abbreviation);     //writer... INSERT COUNT ATTRIBUTE      foreach(DataRow dr in getData.Tables)     {         writer.WriteStartElement('change');         writer.WriteStartElement('user');         writer.WriteAttributeString('userid', dr... WHAT GOES HERE??;                         }                     writer.WriteEndElement(); } 

Answer 1

First off, your foreach is wrong. You need to loop over getData.Tables[0].Rows. If there’s more than 1 table, you need to loop over getData.Tables.

But, the answer is it’s an indexed property. So, dr['userId'] will get you the value.

foreach (DataRow dr in getData.Tables[0].Rows) {    / * blah, blah */    writer.WriteAttributeString('userId', dr['userId']); }
