What you mean correct/modify in this code?
I trying write clear code and need a help for it.
Thank`s!
Your UserControl hasn't instance of BO class. You just define BO class inside SerialPortInitControl, so when you will create instanse of it, it will be like this:
var instBO = new SerialPortInitControl.BO.BO_GetValues()
so, you created object of BO class, but when you stored it in UserConrol?
public partial class SerialPortInitControl : UserControl
{
public class BO
{
public class BO_GetValues
{
public string name;
public string baudRate;
public string paritie;
public string dataBits;
public string stopBits;
}
}
//instance of BO class
public BO BO_Instanse {get;}
//instance of BO.Get_Values class
public BO.BO_GetValues BO_GetValues_Instanse {get;}
public SerialPortInitControl()
{
InitializeComponent();
BO_Instanse = new BO();
BO_GetValues_Instanse = new BO.BO_GetValues();
}
public bool GetValues(out BO.BO_GetValues values, ref string errorMessage)
{
if(BO_Instanse == null)//need real code here
{
values = new BO.BO_GetValues()
{
name = CBX_Name.Text,
baudRate = CBX_BaudRate.Text,
paritie = CBX_Parity.Text,
dataBits = CBX_DataBits.Text,
stopBits = CBX_StopBits.Text,
};
return true;
}
else
{
values = null;
errorMessage = "Checking failed! " + errorMessage;
return false;
}
}
}
So, this will works:
var control = new SerialPortInitControl();
var bo = control.BO_Instanse;
var bo_values = control.BO_GetValues_Instanse;
Also you can create instances of you classes without UserControl class:
var boInstanse = new SerialPortInitControl.BO();
var boGetValues_Instanse = new SerialPortInitControl.BO.BO_GetValues();
public class Personmodel
{
public int Id { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string NickName { get; set; }
public int Points { get; set; }
public int CurrLevel { get; set; }
public int CurrClass { get; set; }
public List<AvatarPicture> Avatars { get; set; } = new List<AvatarPicture>();
public string FullName
{
get { return $"{ FirstName } { LastName }"; }
}

I have some Properties and i want to save some specific property value in json format.Here is my code and i want to save two properties value like SelectedScalesModel and SelectedScales port Can anyone help me with this.
public class SetUpViewModel : ViewModelBase
{
public List<string> ScalesModel { get; set; } = new List<string> { "None", "METTLER-TOLEDO", "DINI ARGEO DFW-DFWK", "ESSAE SI-810" };
private string _selectedScalesModel;
public string SelectedScalesModel
{
get { return _selectedScalesModel; }
set
{
_selectedScalesModel = value;
RaisePropertyChanged("SelectedScalesModel");
}
}
public List<string> ScalesPort { get; set; } = new List<string> { "None", "COM1", "COM2", "COM3", "COM4", "COM5", "COM6", "COM7", "COM8", "COM9", "COM10", "COM11", "COM12", "COM13", "COM14", "COM15" };
private string _selectedScalesPort;
public string SelectedScalesPort
{
get { return _selectedScalesPort; }
set
{
_selectedScalesPort = value;
RaisePropertyChanged("SelectedScalesPort");
}
}
string _text1;
public string BlackLineText
{
get { return _text1; }
set
{
_text1 = value;
RaisePropertyChanged(nameof(BlackLineText));
}
}
public RelayCommand SaveButtonCommand { get; private set; }
public SetUpViewModel()
{
SaveButtonCommand = new RelayCommand(SaveCommand);
}
private void SaveCommand()
{
SetUpViewModel setUpobj = new SetUpViewModel();
string strJsonResult = JsonConvert.SerializeObject(setUpobj);
File.WriteAllText("setup.json", strJsonResult);
MessageBox.Show("File save in Json Format");
}
}
You can try to SerializeObject by anonymous class then carry your expect property instead of SetUpViewModel object.
private void SaveCommand()
{
string strJsonResult = JsonConvert.SerializeObject(
new {
SelectedScalesModel = this.SelectedScalesModel,
SelectedScalesPort = this.SelectedScalesPort
}
);
File.WriteAllText("setup.json", strJsonResult);
MessageBox.Show("File save in Json Format");
}
Note
use this because your property info in your object.
I want to use rest with get method. My code is below;
public class RegisterPage : ContentPage
{
Label label, l4, label2;
public RegisterPage()
{
Button btn = new Button
{
Text = "register"
};
btn.Clicked += Btn_Clicked;
label = new Label();
l4 = new Label();
label2 = new Label();
Content = new StackLayout
{
Children = {
btn,
label,
l4,
label2
}
};
}
private async void Btn_Clicked(object sender, EventArgs e)
{
HttpClient client = new HttpClient();
client.DefaultRequestHeaders.Add(Constants.API_KEY_HEADER_KEY, Constants.API_KEY);
string URL = Constants.URL;
var response = await client.GetAsync(URL);
var content = await response.Content.ReadAsStringAsync();
var result = JsonConvert.DeserializeObject<Models.Result>(content);
label.Text = result.Success.ToString();
l4.Text = result.Error.ToString();
label2.Text = ((RegisteredDevice)result.Retval).Clientuuid + " - " + ((RegisteredDevice)result.Retval).Deviceuuid;
}
}
The url is working good. And my content value has json string. But the serialization is not working.
var result = JsonConvert.DeserializeObject(content);
This code doesn't deserilize.
My model is;
public class Result
{
private object retval = null;
private bool success = false;
private Error error = null;
internal Error Error
{
get { return error; }
set { error = value; }
}
public bool Success
{
get { return success; }
set { success = value; }
}
public object Retval
{
get { return retval; }
set { retval = value; }
}
}
Json:
{
"result":{
"retail":{
"#xsi.type":"registeredDevice",
"clientuuid":"28asgargb-acfe-41dfgsdg51",
"deviceuuid":123456
},
"success":true
}
}
I think the problem comes from :
private object retval = null;
So for me the best way to construct serialization objects in C# is to use this web site :
http://json2csharp.com/
This will tell you if your json is correct and he will generate the classes you need for you, here the classes generated by json2csharp
public class Retail
{
public string __invalid_name__#xsi.type { get; set; }
public string clientuuid { get; set; }
public int deviceuuid { get; set; }
}
public class Result
{
public Retail retail { get; set; }
public bool success { get; set; }
}
public class RootObject
{
public Result result { get; set; }
}
I have been working on a program that requires two class definitions (clsCustomer and clsOrder) and a driver that is used for simulating an order form that calculates totals and prints a mailing label. The instructor provided partial code and I got rid of the previous errors that it had, but when I run the program and enter the information (name, address, quantity, price, etc.) only a "." shows up as the mailing label and both the extension and total price appear as "0.00". I tried playing with it and cannot seem to fix the issue. Here is the code:
namespace CS8
{
public partial class frmCS8 : Form
{
public frmCS8()
{
InitializeComponent();
}
private void btnCalculate_Click(object sender, EventArgs e)
{
string strMailingLabel;
try
{
//Create an instance of clsCustomer using the overloaded constructor
clsCustomer cobjCustomer = new clsCustomer(txtName.Text, txtStreet.Text,
txtCity.Text, txtState.Text, txtZip.Text);
//Build mailing label using the Get methods for Customer.
strMailingLabel = cobjCustomer.Name + "\n" +
cobjCustomer.Street + "\n" +
cobjCustomer.City + ", " +
cobjCustomer.State + " " + cobjCustomer.Zip;
//Display mailing address
lblMailingLabel.Text = strMailingLabel;
//Create an instance of clsOrder using the overloaded constructor
clsOrder cobjOrder = new clsOrder
(txtDescription.Text,
int.Parse(txtQuantity.Text),
decimal.Parse(txtPrice.Text));
//Test the calculate Extended Price method
cobjOrder.calcExtendedPrice();
//Update the totals in shared variables.
cobjOrder.accumulateTotals();
//Test the Get property method of extended priced
lblExtension.Text = cobjOrder.ExtendedPrice.ToString("C");
//Shared properties are accessed using class name
//Test the Get Property methods of ReadOnly Shared properties
lblTotalCount.Text = clsOrder.TotalCount.ToString("N0");
lblTotalPrice.Text = clsOrder.TotalPrice.ToString("C");
}

Use parameters, not class fields:
public clsOrder(string strDescription,
int intQuantity, decimal decPrice)
{
this.Description = strDescription;
this.Quantity = intQuantity;
this.Price = decPrice;
}
public clsCustomer(string strName,
string strStreet, string strCity,
string strState, string strZip)
{
this.Name = strName;
this.Street = strStreet;
this.City = strCity;
this.State = strState;
this.Zip = strZip;

I've been trying for hours to get many-to-many relationship to save with Castle ActiveRecord. What am I doing wrong? I can't find anything in the documentation or on google. There is data in the database.
Courses have a many to many relationship with Books.
Test code.
Database.Course c = new Database.Course();
c.Number = "CS 433";
c.Name = "Databases";
c.Size = 34;
c.Books = Database.Book.FindAll();
c.Save();
Also doesn't work
foreach(Database.Book b in Database.Book.FindAll()){
c.Books.Add(b);
}

Make sure you put the Inverse = true where you want it. From the Castle AR docs,
It is wise to choose one side of the
relation as the owner. The other side,
the non-writable, need to use
Inverse=true.
Put the Inverse = true on the other side of the relationship, like this:
[HasAndBelongsToMany(typeof(Book),
Table = "BookCourse", ColumnKey = "course_id", ColumnRef = "book_id")]
public IList<Book> Books
[HasAndBelongsToMany(typeof(Course),
Table = "BookCourse", ColumnKey = "book_id", ColumnRef = "course_id", Inverse = true)]
public IList<Course> Courses
You also have to add attributes to the top of both classes - at the moment they don't know what tables they're mapped to. Currently you have this:
public class Course : ActiveRecordBase<Course>
Add this (where "course" is the name of your Course table):
[ActiveRecord("course")]
public class Course : ActiveRecordBase<Course>
