Create a user node in firebase database Xamarin.Android

I want to create a node in the firebase database like below:
{
"Users" : {
"SktNBDO4pOgS6wNfFIc5lV8p4u73" : {
"Email" : "user#email.com",
"Name" : "Name Surname"
}
}
}
the code I'm using is:
user = auth.CurrentUser;
//Init Firebase
dataBase = FirebaseDatabase.Instance.GetReference("Users").Child(user.Uid).Child("Name");
var postData = new UserListItemViewModel
{
Name = "Name Surname",
Email = "user#email.com",
};
dataBase.SetValue(postData.Name);
what I want to do is to set all the UserListItemViewModel into the database, like:
user = auth.CurrentUser;
//Init Firebase
dataBase = FirebaseDatabase.Instance.GetReference("Users").Child(user.Uid).Child("Name");
Dictionary<string, UserListItemViewModel> userData = new Dictionary<string, UserListItemViewModel>
{
{
user.Uid,
new UserListItemViewModel
{
Name = "Name Surname",
Email = "user#email.com",
}
}
};
dataBase.SetValue(userData);
The problem with the above code is that userData should be Java.Lang.Object.
I came in this solution following a tutorial in Java suggesting
Map<string, UserListItemViewModel> userData = new HashMap(user.Uid, new UserListItemViewModel
{
Name = "Name Surname",
Email = "user#email.com",
})`
Any help please?

I have done similar function with FCM, you can refer to the following code：

C# Save and repopulate data from array

I am working on a C# program that store the student name, student number, unit number, unit name, mark and attendance in an array. All the data are displayed in a ListView. How can I save the data from the array and then repopulate the array by using a Load Button? Thank you in advance.
public partial class Main : Form
{
public Main()
{
InitializeComponent();
//ListVIEW Properties
listView.View = View.Details;
listView.FullRowSelect = true;
}
private void insert(string StudentNumber, string StudentName, string UnitNumber, string UnitName, string Mark, string combobox)
{
// Array
string[] row = { StudentNumber, StudentName, UnitNumber, UnitName, Mark, combobox };
ListViewItem item = new ListViewItem(row);
listView.Items.Add(item);
}
private void update()
{
//Update
listView.SelectedItems[0].SubItems[0].Text = TXTStudentNumber.Text;
listView.SelectedItems[0].SubItems[1].Text = TXTStudentName.Text;
listView.SelectedItems[0].SubItems[2].Text = TXTUnitNumber.Text;
listView.SelectedItems[0].SubItems[3].Text = TXTUnitName.Text;
listView.SelectedItems[0].SubItems[4].Text = TXTMark.Text;
listView.SelectedItems[0].SubItems[5].Text = comboBox1.Text;
TXTStudentNumber.Text = "";
TXTStudentName.Text = "";
TXTUnitNumber.Text = "";
TXTUnitName.Text = "";
TXTMark.Text = "";
comboBox1.Text = "";
}
private void delete()
{
if (MessageBox.Show("Are you sure?", "Warning", MessageBoxButtons.YesNo, MessageBoxIcon.Warning) == DialogResult.Yes)
{
listView.Items.RemoveAt(listView.SelectedIndices[0]);
}
TXTStudentNumber.Text = "";
TXTStudentName.Text = "";
TXTUnitNumber.Text = "";
TXTUnitName.Text = "";
TXTMark.Text = "";
comboBox1.Text = "";
}
private void btnInsert_Click(object sender, EventArgs e)
{
//Insert
insert(TXTStudentNumber.Text, TXTStudentName.Text, TXTUnitNumber.Text, TXTUnitName.Text, TXTMark.Text, comboBox1.Text);
// Clear All textBox after Pressing Button
TXTStudentNumber.Text = "";
TXTStudentName.Text = "";
TXTUnitNumber.Text = "";
TXTUnitName.Text = "";
TXTMark.Text = "";
comboBox1.Text = "";
}
//Update Button
private void btnUpdate_Click(object sender, EventArgs e)
{
update();
}
//Delete Button
private void btnDelete_Click(object sender, EventArgs e)
{
delete();
}
//Clear Button
private void btnClear_Click(object sender, EventArgs e)
{
TXTStudentNumber.Text = "";
TXTStudentName.Text = "";
TXTUnitNumber.Text = "";
TXTUnitName.Text = "";
TXTMark.Text = "";
comboBox1.Text = "";
}
// ListView
private void listView1_MouseClick(object sender, MouseEventArgs e)
{
TXTStudentNumber.Text = listView.SelectedItems[0].SubItems[0].Text;
TXTStudentName.Text = listView.SelectedItems[0].SubItems[1].Text;
TXTUnitNumber.Text = listView.SelectedItems[0].SubItems[2].Text;
TXTUnitName.Text = listView.SelectedItems[0].SubItems[3].Text;
TXTMark.Text = listView.SelectedItems[0].SubItems[4].Text;
comboBox1.Text = listView.SelectedItems[0].SubItems[5].Text;
}

array is not suitable in this case. Instead use list.
private List<Student> students = new List<Student>();
private void insert(string StudentNumber, string StudentName, string UnitNumber, string UnitName, string Mark, string combobox)
{
Student s = new Student
{
StudentNumber =StudentNumber,
StudentName =StudentName,
UnitNumber =UnitNumber
UnitName =UnitName,
Mark = Mark
Combobox = combobox
};
students.Add(s);
}
public class Student
{
public string StudentNumber{get; set;}
public string StudentName {get; set;}
public string UnitNumber {get; set;}
public string UnitName {get; set;}
public string Mark {get; set;}
public string Combobox {get;set;}
}

Follow the below steps
Add extension Method to convert your object to and from xml
ExtensionMethods class
public static class ExtensionMethods
{
/// <summary>
/// Converts given class to XML using xml serialization
/// </summary>
/// <typeparam name="T">Type of Class</typeparam>
/// <param name="classObject">Class to be serialized</param>
/// <returns>Xml string</returns>
public static string ToXML<T>(this T classObject) where T : class
{
XmlSerializer xmls = new XmlSerializer(typeof(T));
using (MemoryStream ms = new MemoryStream())
{
XmlWriterSettings settings = new XmlWriterSettings();
settings.Encoding = new UTF8Encoding(false);
settings.Indent = true;
settings.IndentChars = "\t";
settings.NewLineChars = Environment.NewLine;
settings.OmitXmlDeclaration = true;
settings.ConformanceLevel = ConformanceLevel.Document;
using (XmlWriter writer = XmlTextWriter.Create(ms, settings))
{
xmls.Serialize(writer, classObject);
}
string xml = Encoding.UTF8.GetString(ms.ToArray());
return xml;
}
}
/// <summary>
/// Converts given XML string to class of type T
/// </summary>
/// <typeparam name="T">Type to be converted</typeparam>
/// <param name="XmlData">xml string</param>
/// <returns>class of Type T</returns>
public static T ToClass<T>(this string XmlData)
{
XmlSerializer serializer = new XmlSerializer(typeof(T));
T newClass;
using (XmlTextReader reader = new XmlTextReader(new StringReader(XmlData)))
{
//reader.Namespaces = false;
newClass = (T)serializer.Deserialize(reader);
}
return newClass;
}
}
create a class to hold student information
student class
public class Student
{
public string StudentNumber{get; set;}
public string StudentName {get; set;}
public string UnitNumber {get; set;}
public string UnitName {get; set;}
public string Mark {get; set;}
public string Combobox {get;set;}
}
In form load check if file exists
Form load
//declare global variable for student list and filepath
List<Student> students = new List<Student>();
string FilePath = AppDomain.CurrentDomain.BaseDirectory + "\\" + Path.GetFileNameWithoutExtension(AppDomain.CurrentDomain.FriendlyName) + ".xml";
private void Form1_Load(object sender, EventArgs e)
{
string XmlData = string.Empty;
if (File.Exists(FilePath))
{
using (StreamReader sr = new StreamReader(FilePath))
{
XmlData = sr.ReadToEnd();
}
students = XmlData.ToClass<List<Student>>();
}
}
In insert,update and delete operations save the xml file to file system
save xml
string XmlData = students.ToXML();
File.WriteAllText(FilePath, XmlData);

Call Salesforce API to Add Leads using ASP.net

I am trying to call Salesforce Parnter wsdl to Create Leads to their system through my c# code.
but its giving me error:

}
Response.Write(result);
}
}
public class Contact
{
public String fname { get; set; }
public String lname { get; set; }
public String mobile { get; set; }
}
}
please help, very much new to this salesforce API.

You need to create an array of SObjects, not contacts, so do
sforce.sObject[] contacts = { contact };
string result;
sforce.SaveResult[] createResults = binding.create(contacts);

Silverlight 4.0 reading complex xml with linq

I'm stuck with following XML problem.
This is my XML file:
<POIs lastUsedId="9000010">
<POI id="9000010" name="München"><Latitude>48.139126</Latitude><Longitude>11.5801863</Longitude>
<Address>muenchen</Address><PhotoDescription>Hofbräuhaus</PhotoDescription>
<Photos directory="_x002F_pics"><PhotoFile>pic4poi_9000010-01.jpg</PhotoFile>
<PhotoFile>pic4poi_9000010-02.jpg</PhotoFile><PhotoFile>pic4poi_9000010-03.jpg</PhotoFile>
<PhotoFile>pic4poi_9000010-04.jpg</PhotoFile></Photos>
<InformationFile>infos\info4poi_9000010.txt</InformationFile></POI>
</POIs>
And here is my code to read the file:
XDocument doc = XDocument.Load(s);
lastID = Int32.Parse(doc.Root.Attribute("lastUsedId").Value.ToString());
CultureInfo cultureInfo = new CultureInfo("en-GB");
var pois = from res in doc.Descendants("POI")
select new
{
id = Int32.Parse(res.Attribute("id").Value.ToString()),
name = res.Attribute("name").Value.ToString(),
latitude = Double.Parse(res.Element("Latitude").Value, cultureInfo),
longitude = Double.Parse(res.Element("Longitude").Value, cultureInfo),
address = res.Element("Address").Value.ToString(),
photoDesc = res.Element("PhotoDescription").Value.ToString(),
photoDir = XmlConvert.DecodeName(res.Element("Photos").Attribute("directory").Value.ToString()),
photoFiles = from a in doc.Descendants("Photos")
select new
{
photo = a.Element("PhotoFile").Value.ToString()
},
info = res.Element("InformationFile").Value.ToString()
};
foreach (var poi in pois)
{
IEnumerable<string> pF = (poi.photoFiles as IEnumerable<string>);
List<string> photoFiles = null;
if(pF != null)
photoFiles = pF.ToList<string>();
AddPushpin(poi.id, poi.name, poi.latitude, poi.longitude, poi.address, poi.photoDesc, poi.photoDir, photoFiles, poi.info);
};
I'm unsure about the part with the PhotoFiles because I get an unknown Object error when I try to read the Pushpin.
This what my Pushpin looks like:
public class MyPushpin : Pushpin
{
public int ID { get; set; }
public string Address { get; set; }
public string PhotoDesc { get; set; }
public string PhotoDir { get; set; }
public List<string> PhotoFiles { get; set; }
public MyPushpin() { }
public MyPushpin(int id, string name, double latitude, double longitude, string address, string photoDesc, string photoDir, List<string> photoFiles, string info)
{
Location loc = new Location(latitude, longitude);
this.ID = id;
this.Location = loc;
this.Name = name;
this.Address = address;
this.PhotoDesc = photoDesc;
this.PhotoDir = photoDir;
this.PhotoFiles = photoFiles;
this.Tag = info;
}
public void Update(string name , string photoDesc, List<string> photoFiles, string info)
{
this.Name = name;
this.PhotoDesc = photoDesc;
this.PhotoFiles = photoFiles;
this.Tag = info;
}
public override string ToString()
{
return String.Format("{0} - {1}", this.ID, this.Location, this.Address, this.PhotoDesc, this.PhotoDir, this.Tag);
}
And that's the code how I would like to use the file info in the custom Pushpin:
public partial class Gallery : ChildWindow
{
List<string> pics = null;
public Gallery(MyPushpin currentPin)
{
InitializeComponent();
pics = currentPin.PhotoFiles;
Loaded += (a, b) => {
LoadImages();
};
}
private void OKButton_Click(object sender, RoutedEventArgs e)
{
this.DialogResult = true;
Close();
}
private void CancelButton_Click(object sender, RoutedEventArgs e)
{
this.DialogResult = false;
Close();
}
private void LoadImages()
{
List<Picture> coll = new List<Picture>();
pics.ForEach(delegate(String url)
{
coll.Add(AddPicture("url"));
});
//coll.Add(AddPicture("/pics/pic4poi_9000010-01.jpg"));
//coll.Add(AddPicture("/pics/pic4poi_9000010-02.jpg"));
//coll.Add(AddPicture("/pics/pic4poi_9000010-03.jpg"));
//coll.Add(AddPicture("/pics/pic4poi_9000010-04.jpg"));
Preview.Source = new BitmapImage(
new Uri(
"/pics/pic4poi_9000010-01.jpg",
UriKind.Relative));
lbImage.ItemsSource = coll;
}
private Picture AddPicture(string path)
{
return new Picture
{
Href = new BitmapImage(
new Uri(
path,
UriKind.Relative))
};
}
private void lbImage_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
Preview.Source = ((Picture)lbImage.SelectedItem).Href;
}
}
public class Picture
{
public ImageSource Href { get; set; }
THX for your time

Could you please describe the problem that you are having in more detail. Have you debugged into it, where does it fail, what is the exception? What do you expect it to do.
Off the top of my head, this code looks wrong:
photoFiles = from a in doc.Descendants("Photos")
select new
{
photo = a.Element("PhotoFile").Value.ToString()
},
Replace doc with res, because you want the child elements of the current element, not of the document. Also you can use Elements here instead of Descendants since they are direct children. Also since there are multiple photo files, try a SelectMany (from a ... from b ...):
photoFiles = from a in res.Elements("Photos")
from b in a.Elements("PhotoFile")
select new
{
photo = b.Value.ToString()
},
