Missing Schema Info

I am getting this error message n Visual Studio: "Could not find Schema Information Number, Name, Period, a0 and aJ." I have a working schema "SemiMajorAxis.xsd" but I do not know how to use it. Later in the program I deal with the DataTable
SemiMajorAxis.aspx.cs
DataSet dsread = new DataSet();
DataTable dtread = new DataTable();
dsread.ReadXml(Server.MapPath("SemiMajorAxis.xml"));
dtread = dsread.Tables[0];
XDocument xmldoc = XDocument.Load(Server.MapPath("SemiMajorAxis.xml"));
var elements = from data in xmldoc.Descendants("planet")
select new
{
Numberp = (int)data.Element("Number"),
Namep = (string)data.Element("Name"),
Pyrsp = (double)data.Element("Period"),
a0p = (double)data.Element("a0"),
aJp = (double)data.Element("aJ")
};
foreach (var element in elements)
{
m = m + 1;
num[m] = element.Numberp;
name[m] = element.Namep;
a0[m] = element.a0p;
aJ[m] = element.aJp;
a[m] = a0[m] + aJ[m] * J;

Reading XML with different names to Combobox C#

looks like a very simple task by i'm very new to c# and can't seem to find the right answer for this
i have the below xml structure (elements vary in quantity)
<config>
<extras>
<dir_update>C:\extension\update.exe</dir_update>
</extras>
<connection_MAIN>
<ip>LOCALHOST,1433</ip>
<bd>DATA</bd>
<user>sa</user>
<password>gzqs=</password>
</connection_MAIN>
<connection_LOBBY>
<ip>10.0.0.2,1433</ip>
<bd>DATA</bd>
<user>sa</user>
<password>I/wqqZIgzqs=</password>
<caixa>5yIz5GPu80s=</caixa>
<printer>cARrmGLQlztLiUDxIJqoPkvJabIiyI9ye4H7t+4muYk=</printer>
</connection_LOBBY>
<connection_FRONT>
<ip>10.0.0.5,1433</ip>
<bd>FIELDS</bd>
<user>sa</user>
<password>I/wqqZIgzqs=</password>
</connection_FRONT>
</config>
I'm already getting the elements that start with "connection_" in my combobox and i want the values inside the <ip>, <bd>, <user> and <password> when i select the connection on the combobox.
The problem i'm getting is that it's returning the word itself not the value inside on the code below
private void Form1_Load(object sender, EventArgs e)
{
using(DataSet ds = new DataSet())
{
ds.ReadXml(textBox1.Text);
foreach(DataTable dt in ds.Tables)
{
if (dt.ToString().Contains("conection_"))
{
comboBox1.Items.Add(dt.ToString().Replace("conection_", ""));
}
}
comboBox1.SelectedIndex = 0;
}
}
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
using(DataSet ds = new DataSet())
{
ds.ReadXml(textBox1.Text);
string v = comboBox1.Text.ToString();
string ip = ds.Tables[$"conection_{v}"].Columns[0].ToString();
}
}
Variable ip is getting the value "ip" and i want "LOCALHOST,1433" when i select the first option on my combobox in this example.
Also i want to search for column value by the name ("ip", "bd"), but i seem to only get results when using Columns[0], Columns[1].
I've followed some guides that i've looked around, but they seem to not work on this format of xml or i'm looking at it the wrong way.
Any help is appreciated.

There is no need to use DataSet and DataTable data types. The best API to handle XML is LINQ to XML.
Check it out below.
c#
void Main()
{
const string MAIN = "connection_MAIN";
string IP = string.Empty;
string bd = string.Empty;
string user = string.Empty;
string password = string.Empty;
XElement xml = XElement.Parse(#"<config>
<extras>
<dir_update>C:\extension\update.exe</dir_update>
</extras>
<connection_MAIN>
<ip>LOCALHOST,1433</ip>
<bd>DATA</bd>
<user>sa</user>
<password>gzqs=</password>
</connection_MAIN>
<connection_LOBBY>
<ip>10.0.0.2,1433</ip>
<bd>DATA</bd>
<user>sa</user>
<password>I/wqqZIgzqs=</password>
<caixa>5yIz5GPu80s=</caixa>
<printer>cARrmGLQlztLiUDxIJqoPkvJabIiyI9ye4H7t+4muYk=</printer>
</connection_LOBBY>
<connection_FRONT>
<ip>10.0.0.5,1433</ip>
<bd>FIELDS</bd>
<user>sa</user>
<password>I/wqqZIgzqs=</password>
</connection_FRONT>
</config>");
// get needed connection fragment
IEnumerable<XElement> fragment = xml.Descendants(MAIN);
// get all needed elements one by one
IP = fragment.Elements("ip")?.FirstOrDefault().Value;
bd = fragment.Elements("bd")?.FirstOrDefault().Value;
user = fragment.Elements("user")?.FirstOrDefault().Value;
password = fragment.Elements("password")?.FirstOrDefault().Value;
}

Using Xml Linq I put results in to a datatable
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
using System.Data;
namespace ConsoleApplication1
{
class Program
{
const string FILENAME = #"c:\temp\test.xml";
static void Main(string[] args)
{
DataTable dt = new DataTable();
dt.Columns.Add("name", typeof(string));
dt.Columns.Add("ip", typeof(string));
dt.Columns.Add("bd", typeof(string));
dt.Columns.Add("user", typeof(string));
dt.Columns.Add("password", typeof(string));
XDocument doc = XDocument.Load(FILENAME);
foreach(XElement connection in doc.Descendants().Where(x => x.Name.LocalName.StartsWith("connection_")))
{
dt.Rows.Add(new object[] {
((string)connection.Name.LocalName).Substring(((string)connection.Name.LocalName).IndexOf("_") + 1),
(string)connection.Element("ip"),
(string)connection.Element("bd"),
(string)connection.Element("user"),
(string)connection.Element("password")
});
}
Dictionary<string, DataRow> dict = dt.AsEnumerable()
.GroupBy(x => x.Field<string>("name"), y => y)
.ToDictionary(x => x.Key, y => y.FirstOrDefault());
string ip = dict["LOBBY"].Field<string>("ip");
}
}
}

XML to DataTable (list item)

Here is my schema of xml.
<?xml version="1.0" encoding="utf-8"?>

I need read this XML file and fill the datatable.
I'm trying with DataSet.
DataSet ds = new DataSet();
ds.ReadXml(path);
DataTable dt = ds.Tables[0];
And my output datatable is like.
I need to show my items on table. Is there any way to read properly ?

Try following xml linq which creates a separate row for each string :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
using System.Data;
namespace ConsoleApplication51
{
class Program
{
const string FILENAME = #"c:\temp\test.xml";
static void Main(string[] args)
{
DataTable dt = new DataTable();
dt.Columns.Add("KEY", typeof(string));
dt.Columns.Add("RESULTING_ID", typeof(string));
dt.Columns.Add("TYPE", typeof(string));
XDocument doc = XDocument.Load(FILENAME);
XElement root = doc.Root;
XNamespace ns = root.GetDefaultNamespace();
foreach (XElement resultingString in doc.Descendants(ns + "Resultstring"))
{
string key = (string)resultingString.Element("Key");
string type = (string)resultingString.Element("Type");
string ids = string.Join(";", resultingString.Descendants("string").Select(x => (string)x));
dt.Rows.Add(new object[] { key, ids, type });
}
}
}
}
Code to put each string in a separate column
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
using System.Data;
namespace ConsoleApplication51
{
class Program
{
const string FILENAME = #"c:\temp\test.xml";
static void Main(string[] args)
{
XDocument doc = XDocument.Load(FILENAME);
XElement root = doc.Root;
XNamespace ns = root.GetDefaultNamespace();
int maxString = doc.Descendants(ns + "Resultstring").Select(x => x.Descendants("string").Count()).Max();
DataTable dt = new DataTable();
dt.Columns.Add("KEY", typeof(string));
dt.Columns.Add("TYPE", typeof(string));
for (int i = 0; i < maxString; i++)
{
dt.Columns.Add("RESULTING_ID_" + (i + 1).ToString(), typeof(string));
}
foreach (XElement resultingString in doc.Descendants(ns + "Resultstring"))
{
string key = (string)resultingString.Element("Key");
string type = (string)resultingString.Element("Type");
List<string> row = resultingString.Descendants("string").Select(x => (string)x).ToList();
row.Insert(0, key);
row.Insert(1, type);
dt.Rows.Add(row.ToArray());
}
}
}
}

With Cinchoo ETL - an open source library, you can easily convert Xml file to DataTable with few lines of code.
For your sample xml file, you can extract the data into datatable as below
using (var p = new ChoXmlReader(** YOUR XML FILE **)
.WithField("Key")
.WithField("Value", xPath: "/Values/string")
)
{
var dt = p.SelectMany(r => ((Array)r.Value).OfType<string>().Select(r1 => new { Key = r.Key, Value = r1})).AsDataTable();
}
Output:
Hope it helps.

your Resultstring xml node is repeating. Below code is working for me
<Resultstring>
<Key>Blablabla : </Key>
<Values>
<string>79,0441326460292</string>
<string>76,0959542079328</string>
<string>74,3061819154758</string>
<string>78,687039788779</string>
</Values>
<Type>list</Type>
<Key>Blablabla : </Key>
<Values>
<string>87,7110395931923</string>
</Values>
<Type>double</Type>
</Resultstring>
Dataset code
DataSet ds = new DataSet();
ds.ReadXml(path);
DataTable dtKey = ds.Tables[0];
DataTable dtValues = ds.Tables[1];
DataTable dtstring = ds.Tables[2];
DataTable dtType = ds.Tables[3];

How to convert datatable to list<> or array?

I want to get all the data from a table using the code below:
CameraBUS cameraBus = new CameraBUS(); //Contain class provider access to DAO for GetByAllCamera.
DataTable dt = cameraBus.Camera_GetByAllCamera(); //select * from table Camera
foreach (DataRow row in dt.Rows)
{
CameraDTO camera = new CameraDTO(row);
if(camera.IDKhuVuc == 4)
{
OpenCamera(camera.ViTri, camera.TaiKhoan, camera.MatKhau, camera.IP);
}
if(camera.IDKhuVuc == 3)
{
OpenCamera(camera.ViTri, camera.TaiKhoan, camera.MatKhau, camera.IP);
}
}
If camera.IDKhuVuc have 7 rows or more. It's always start StartThead1 and my program stop not working.
Example:
My data has 4 rows, but this code can't get 4 rows of 4 cameras. It only opens the first and last cameras.
When I debug my program, it runs 2 rows (rows 2, 3). But when I run my program, it's not opening camera 2 and camera 3.
I think I should use List<> or array. How could I fix this?
Class OpenCamera():
private void OpenCamera(bool position, string username, string password, string ipAddress)
{
if (!position)
{
axLiveX1.IpAddress = ipAddress;
axLiveX1.UserName = username;
axLiveX1.Password = password;
axLiveX1.DataPort = 5550;
axLiveX1.CommandPort = 4550;
axLiveX1.AudioDataPort = 6550;
axLiveX1.DefaultCam = 8;
axLiveX1.OnGetPicture += new AxLIVEXLib._DLiveXEvents_OnGetPictureEventHandler(axLiveX1_OnGetPicture);
axLiveX1.AutoLogin = true;
if (axLiveX1.Connect())
{
}

axLiveX2.DefaultCam = 8;
axLiveX2.OnGetPicture += new AxLIVEXLib._DLiveXEvents_OnGetPictureEventHandler(axLiveX2_OnGetPicture);
axLiveX2.AutoLogin = true;
axLiveX2.Connect();
axLiveX2.StartGrapImage(true);
}
else
{
axLiveX3.IpAddress = ipAddress;

axLiveX3.DefaultCam = 8;
axLiveX3.OnGetPicture += new AxLIVEXLib._DLiveXEvents_OnGetPictureEventHandler(axLiveX3_OnGetPicture);
axLiveX3.AutoLogin = true;
axLiveX3.Connect();
axLiveX3.StartGrapImage(true);
axLiveX4.IpAddress = ipAddress;
axLiveX4.UserName = username;
axLiveX4.Password = password;
axLiveX4.DataPort = 5550;
axLiveX4.CommandPort = 4550;
axLiveX4.AudioDataPort = 6550;
axLiveX4.DefaultCam = 8;
axLiveX4.OnGetPicture += new AxLIVEXLib._DLiveXEvents_OnGetPictureEventHandler(axLiveX4_OnGetPicture);
axLiveX4.AutoLogin = true;
axLiveX4.Connect();
axLiveX4.StartGrapImage(true);
}
}

Try something like this
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
DataTable dt = new DataTable();
dt.Columns.Add("Col A", typeof(int));
dt.Columns.Add("Col B", typeof(int));
dt.Columns.Add("Col C", typeof(int));
dt.Rows.Add(new object[] { 1, 2, 3});
dt.Rows.Add(new object[] { 10, 20, 30 });
dt.Rows.Add(new object[] { 100, 200, 300 });
List<DataRow> rows = dt.AsEnumerable().Select(x => x).ToList();
var numbers = dt.AsEnumerable().Select(x => x.ItemArray).ToList();
}
}
}
​
​
You can get data of any cell like this with your original code
foreach (DataRow row in dt.Rows)
{
string colA = (string)row["Col A"];
}​
To Get entire column try something like this
var colA = dt.AsEnumerable().Select(x => x.Field<string>("Col A")).ToList();​
