setting value of a property in source list

I have 2 lists
public class EmailDetails
{
public int EmailMasterID { get; set; }
public string Name { get; set; }
public string Body { get; set; }
public string Number { get; set; }
public string IsModified { get; set; }
}
public class EmailDetailsActual
{
public string ProgramNumber { get; set; }
public string IsModified { get; set; }
public int EmailMasterID_FK { get; set; }
}
I need to set value of IsModified column to YES in EmailDetails list if EmailMasterID = EmailMasterID_FK (from EmailDetailsActual list) . If not, then set value to NO. The final result should be EmailDetails list.

im not sure but i put new EmailDetailsActual in EmailDetails and I put the details for that (ProgramNumber , IsModified , EmailMasterID_FK)
and then I put input to when Call EmailDetails , should fill inputs like
EmailDetails p1 = new EmailDetails("ProgramNumber", "IsModified", 0000);
after i put IsModified Get properties in EmailDetails >>
if (EmailMasterID == EDA.EmailMasterID_FK)
{
return "yes";
}
else
{
return "no";
}
// EDA is new EmailDetailsActual
And I accessed it values ​​in a this way (accessed EmailMasterID_FK (we create new EmailDetailsActual ) )
and its my finally >>>
public class EmailDetails
{
EmailDetailsActual EDA = new EmailDetailsActual();
public EmailDetails(string ProgramNumber , string IsModified , int EmailMasterID_FK)
{
EDA.ProgramNumber = ProgramNumber;
EDA.IsModified = IsModified;
EDA.EmailMasterID_FK = EmailMasterID_FK;
}
public int EmailMasterID { get; set; }
public string Name { get; set; }
public string Body { get; set; }
public string Number { get; set; }
public string IsModified { get
{
if (EmailMasterID == EDA.EmailMasterID_FK)
{
return "yes";
}
else
{
return "no";
}
}
}
}
public class EmailDetailsActual
{
public string ProgramNumber { get; set; }
public string IsModified { get; set; }
public int EmailMasterID_FK { get; set; }
}
this is example to work >>
EmailDetails p1 = new EmailDetails("ProgramNumber", "IsModified",9991);
p1.EmailMasterID = 9992;
Console.WriteLine(p1.IsModified);
its output no bc EmailMasterID (9991) its not same with EmailMasterID_FK(9992)
I hope I able to help you :)

c# convert existing class to use properties correctly

I have the following classes:
class Given
{
public string text = "";
public List<StartCondition> start_conditions = new List<StartCondition>();
};
class StartCondition
{
public int index = 0;
public string device = "unknown";
public string state = "disconnected";
public bool isPass = false;
};
I want to convert them into c# properties (using get; and set;)
Looking at this question: what-is-the-get-set-syntax-in-c, it seems I can make a property nice and easy like this:
class Given
{
public string text { get; set; }
public List<StartCondition> start_conditions { get; set; }
};
class StartCondition
{
public int index { get; set; }
public string device { get; set; }
public string state { get; set; }
public bool isPass { get; set; }
};
But now I don't know how I should add my initialisations, because I want the same start values as I had before, or for the List container I want it to be new'ed.
What is the best way to achieve this?

The ability to have auto property initializers is included since C# 6.0. The syntax is:
public int X { get; set; } = x; // C# 6 or higher

Use a constructor. So your class would look like this:
public class StartCondition
{
public int index { get; set; }
public string device { get; set; }
public string state { get; set; }
public bool isPass { get; set; }
// This is the constructor - notice the method name is the same as your class name
public StartCondition(){
// initialize everything here
index = 0;
device = "unknown";
state = "disconnected";
isPass = false;
}
}

Create a Constructor to start your class instance with the default values
class Given
{
public Given(){
this.text = "";
start_conditions = new List<StartCondition>();
}
public string text { get; set; }
public List<StartCondition> start_conditions { get; set; }
};
class StartCondition
{
public StartCondition(){
this.index = 0;
this.device = "unknown";
this.state = "disconnected";
this.isPass = false;
}
public int index { get; set; }
public string device { get; set; }
public string state { get; set; }
public bool isPass { get; set; }
};
Now you can create your instances with the default values by using StartCondition A = new StartCondition();

If you are not using C# 6+ (or even if you are), you can explicitly declare your backing variables for properties:
public class Given
{
private string _text = string.Empty;
private List<StartCondition> _start_conditions = new List<StartCondition>();
public string text { get{ return _text; } set{ _text = value; } }
public List<StartCondition> start_conditions { get{ return _start_conditions; } set{ _start_conditions = value; } }
}
This allows you to set your initializations as before.

How to populate list as class object?

How do you populate a list as a class object? For example, this does not work:
[DataContract]
public class JsonReviewFormFields
{
[DataMember]
public PersonalDevelopmentPlan personalDevelopmentPlan { get; set; }
}
public class PersonalDevelopmentPlan
{
public List<ShortTerm> shortTerm { get; set; }
public List<LongTerm> longTerm { get; set; }
}
public class ShortTerm
{
public string workRelated { get; set; }
public string structured { get; set; }
public string informal { get; set; }
public string reviewDate { get; set; }
}
public class LongTerm
{
public string workRelated { get; set; }
public string structured { get; set; }
public string informal { get; set; }
public string reviewDate { get; set; }
}
This is controller action:
public JsonReviewFormFields GetReviewForm()
{
PersonalDevelopmentPlan personalDevelopmentPlan = new PersonalDevelopmentPlan();
List<ShortTerm> _itemsShort = new List<ShortTerm>();
_itemsShort.Add(new ShortTerm { workRelated = "workRelated text", structured = "structured text", informal = "informal text", reviewDate = "reviewDate" });
jsonReviewFormFields.personalDevelopmentPlan.shortTerm = _itemsShort;
List<LongTerm> _itemsLong = new List<LongTerm>();
_itemsLong.Add(new LongTerm { workRelated = "workRelated text", structured = "structured text", informal = "informal text", reviewDate = "reviewDate" });
jsonReviewFormFields.personalDevelopmentPlan.longTerm = _itemsLong;
return jsonReviewFormFields;
}
The code crashes at
jsonReviewFormFields.personalDevelopmentPlan.shortTerm = _itemsShort;
It's probably a basic object orientated error. How do you populate the list?

You are not instantiating it, you have to instantiated the type first:
jsonReviewFormFields.personalDevelopmentPlan = new PersonalDevelopmentPlan();
and then set property of it:
jsonReviewFormFields.personalDevelopmentPlan.shortTerm = _itemsShort
before that you also have to instantiate main class which i don't see in your controller action anywhere :
JsonReviewFormFields jsonReviewFormFields = new JsonReviewFormFields();

C# Accessing a methods value dynamically using a string

I am currently setting some strings via this method:
string marketlabel = allmarketdata.#return.markets.COLXPM.label.ToString();
I would like to set the market label dynamically by having a string for the actual market choice.
string currentMarketSelected= this.marketTextBox.Text; // Specific market: COLXPM
string marketlabel=allmarketdata.#return.markets.currentMarketSelected.label.ToString();
I have been searching for a few hours and probably am not explaining correctly. I tried some stuff with reflections with no success. Basically what I want to do is have a textbox or list which contains all the market names and based on which one is selected start setting the data.
Above is the best type of example of what I want to do even though it is not syntactically possible to use a variable in place.
public class Markets
{
public COLXPM COLXPM { get; set; }
//Lots of markets below here
}
public class COLXPM
{
public string marketid { get; set; }
public string label { get; set; }
public string lasttradeprice { get; set; }
public string volume { get; set; }
public string lasttradetime { get; set; }
public string primaryname { get; set; }
public string primarycode { get; set; }
public string secondaryname { get; set; }
public string secondarycode { get; set; }
public List<Recenttrade> recenttrades { get; set; }
public List<Sellorder> sellorders { get; set; }
public List<Buyorder> buyorders { get; set; }
}
public class Return
{
public Markets markets { get; set; }
}
public class RootObject
{
public int success { get; set; }
public Return #return { get; set; }
}
The proposed solution below that worked
string currentMarketSelected = "DOGEBTC"; // Just selecting one of the markets to test it works
var property = allmarketdata.#return.markets.GetType().GetProperty(currentMarketSelected);
dynamic market = property.GetMethod.Invoke(allmarketdata.#return.markets, null);
string marketlabel = market.label.ToString(); //Gets all my selected market data

Here is a solution using reflection.
string currentMarketSelected= this.marketTextBox.Text; // Specific market: COLXPM
var property = allmarketdata.#return.markets.GetType().GetProperty(currentMarketSelected);
dynamic market = property.GetGetMethod().Invoke(allmarketdata.#return.markets, null);
string marketlabel=market.label.ToString();

You need something like this:
public class Markets
{
public COLXPM this[string key]
{
get
{
COLXPM colxpm;
switch (key)
{
// TODO : use "key" to select instance of COLXPM;
case "example1":
colxpm = ...;
break;
default:
throw new NotSupportedException();
}
return colxpm;
}
}
}
Then you can do something like:
string marketlabel=allmarketdata.#return.markets[currentMarketSelected]label.ToString();
This is an indexed property.

Set Properties within base function and call function in child function inheritance

I am trying to refactor some old code and wanted to create more logical inheritance.
We have struct Custom Class which we have separated into (3) levels:
AccountView > Details > Full with inheritance. We set the properties of each one as needed.
After looking at the setters, we wanted to combine them into a single class 'SetAccountProp' with methods that set the properties.
We have the 'CustomerBaseView' where we pass in Models ACCOUNT data which works.
Now for the CustomerDetailView pass the same Model ACCOUNT data, but we would like to fill the properties of 'CustomerBaseView' use function 'CustomerBaseView' then fill the details.
Also, for CustomerFullView pass the Model ACCOUNT data, and fill the properties of 'CustomerBaseView' THEN 'CustomerBaseView' and then the remaining fields for CustomerFullView.
How can I call and fill the 'CustomerBaseView' within the 'CustomerDetailView' function? Do I initialize new AccountsView(); in each function?
Not sure how to finish up the refactor without repeating the:
// -- CustomView <--- replace with func?
view.Email = data.Email;
view.Active = data.Active;
view.FirstName = data.FirstName;
view.LastName = data.LastName;
in the Details and Full functions.
CODE
namespace BLL.Presenters
{
public class AccountsView
{
public string Email { get; set; }
public bool Active { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
}
public class Details : AccountsView
{
public bool Administrator { get; set; }
public DateTime? LastLogin { get; set; }
}
public class Full : Details
{
public Guid ID { get; set; }
public DateTime Created { get; set; }
public DateTime Modified { get; set; }
public string FullName { get; set; }
}
public class SetAccountProp
{
public static AccountsView CustomerBaseView(Account data)
{
var view = new AccountsView();
view.Email = data.Email;
view.Active = data.Active;
view.FirstName = data.FirstName;
view.LastName = data.LastName;
return view;
}
public static Details CustomerDetailView(Account data)
{
var view = new Details();
// -- CustomView <--- replace with func?
view.Email = data.Email;
view.Active = data.Active;
view.FirstName = data.FirstName;
view.LastName = data.LastName;
// -- Details
view.Administrator = data.Administrator;
view.LastLogin = data.LastLogin;
return view;
}
public static Full CustomerFullView(Account data)
{
var view = new Full();
// -- CustomView <--- replace with func?
view.Email = data.Email;
view.Active = data.Active;
view.FirstName = data.FirstName;
view.LastName = data.LastName;
// -- Details <--- replace with func?
view.Administrator = data.Administrator;
view.LastLogin = data.LastLogin;
// -- Full
view.ID = data.ID;
view.Created = data.Created;
view.Modified = data.Modified;
view.FullName = data.LastName + ", " + data.FirstName;
return view;
}
}
}

Using constructor chaining, you could have something like this:
Each constructor calls it's base class' constructor first, so you don't have to repeat code.
namespace BLL.Presenters
{
using System;
public class Account // dummy to make it compile
{
public string Email;
public bool Active;
public string FirstName;
public string LastName;
public bool Administrator;
public DateTime? LastLogin;
public Guid ID;
public DateTime Created;
public DateTime Modified;
}
public class AccountsView
{
public string Email { get; set; }
public bool Active { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public AccountsView(Account data)
{
this.Email = data.Email;
this.Active = data.Active;
this.FirstName = data.FirstName;
this.LastName = data.LastName;
}
}
public class Details : AccountsView
{
public bool Administrator { get; set; }
public DateTime? LastLogin { get; set; }
public Details(Account data) : base(data)
{
this.Administrator = data.Administrator;
this.LastLogin = data.LastLogin;
}
}
public class Full : Details
{
public Guid ID { get; set; }
public DateTime Created { get; set; }
public DateTime Modified { get; set; }
public string FullName { get; set; }
public Full(Account data) : base(data)
{
this.ID = data.ID;
this.Created = data.Created;
this.Modified = data.Modified;
this.FullName = data.LastName + ", " + data.FirstName;
}
}
class Program
{
static void Main()
{
Console.WriteLine();
Console.ReadLine();
}
}
}

Why not something like this:
public class CustomerBase
{
public string Email { get; private set; }
public bool Active { get; private set; }
public string FirstName { get; private set; }
public string LastName { get; private set; }
protected void SetAccountInfo(Account account)
{
this.Email = account.Email;
this.Active = account.Active;
this.FirstName = account.FirstName;
this.LastName = account.LastName;
}
}
public class CustomerA : CustomerBase
{
public string IsAdmin { get; private set; }
public DateTime? LastLogin { get; private set; }
public void SetAccountInfo(Account account)
{
base.SetAccountInfo(account);
this.IsAdmin = account.IsAdmin;
this.LastLogin = account.LastLogin;
}
}
public class Account
{
//your properties
public string Email { get; set; }
public bool Active { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string IsAdmin { get; set; }
public DateTime? LastLogin { get; set; }
}
Or let the SetAccountInfo() return this
public CustomerA SetAccountInfo(Account account)
{
base.SetAccountInfo(account);
this.IsAdmin = account.IsAdmin;
this.LastLogin = account.LastLogin;
return this;
}
