I want to Read Only Sections and Mark in Tabular Format. I am using below code to read this But it is giving Error Table Schema 'Component' Already Exists .

C#

DataTable dt = new DataTable();
        DataColumn dc = new DataColumn("Mark");
        DataColumn dc1 = new DataColumn("Sections ");
        dt.Columns.Add(dc);
        dt.Columns.Add(dc1);
        DataSet dSet = new DataSet();


        if (File.Exists(xmlpath2))
        {

            XmlTextReader Reader1 = new XmlTextReader(xmlpath2);



            dSet.ReadXml(Reader1, XmlReadMode.Auto);


            for (int i = 0; i < dSet.Tables[0].Rows.Count; i++)
            {
                DataRow rows = dSet.Tables[0].Rows[i];
                DataRow myRow = dt.NewRow();
                myRow["Mark"] = rows["Mark"];
                myRow["Sections "] = rows["Sections "];

                dt.Rows.Add(myRow);
            }


            GridView1.DataSource = dt;
            GridView1.DataBind();

        }

Solution 1

giving Error Table Schema 'Component' Already Exists
Here: dSet.ReadXml(Reader1, XmlReadMode.Auto); OR myRow["Mark"] = rows["Mark"]; ?

If so, there are two 'mark' in your xml file. Thus access to 'mark' field in dataset table formed can be an issue.

Hi,

below code may be helpful to you,

C#

string xmlstring = @"<Parts>
                                  <Part>
                                       <Section>3003512</Section>
                                       <Mark>RP-103</Mark>
                                       <Length>4950</Length>
                                        <Components>
                                               <Section>3003512</Section>
                                               <Mark>RP-103</Mark>
                                               <Length>4950</Length>
                                               <Remark>System Generated </Remark>
                                        </Components>
                                        <Remark>No Comments </Remark>
                                  </Part>

                                  <Part>
                                       <Section>3003512</Section>
                                       <Mark>RP-103</Mark>
                                       <Length>4950</Length>
                                       <Components />
                                       <Remark>No Comments </Remark>
                                   </Part>
                               </Parts>";

           XDocument xd = XDocument.Parse(xmlstring);
           var result = xd.Descendants("Part").Select(s => new {Section = s.Element("Section"), Mark = s.Element("Mark")});

One more thing, your xml is not correct. please compare your data with my xmlstring variable value. you will find out your problem.

thanks
