Ich nehme WCF Rest Service in eckige js Anwendung. Ich versuche Kontoinformationen basierend auf der Kontonummer zu erhalten. Das Problem ist jedoch, dass der Text Account_Type dreimal angezeigt wird und dann die Werte angezeigt werden.Angular Application Data Binding funktioniert nicht
Hier ist der Methodencode.
public string AccountDetails(string Account_Number)
{
var accountNumber = int.Parse(Account_Number);//It could be better to use TryParse
using (HalifaxDatabaseEntities context = new HalifaxDatabaseEntities())
{
var inOut = context.Current_Account_Deposit.Where(x => x.Account_Number == accountNumber).Select(w => new AccountTransaction
{
Account_Number = w.Account_Number,
Account_Balance = (decimal?)0M,
Deposit = (decimal?)w.Amount,
Withdrawal = (decimal?)null,
Date = w.Date,
Account_Type=null,
Account_Holder_Tittle = null,
Account_Holder_FirstName =null,
Account_Holder_LastName = null
}).Union(context.Current_Account_Withdraw.Where(x => x.Account_Number == accountNumber).Select(d => new AccountTransaction
{
Account_Number = d.Account_Number,
Account_Balance = (decimal?)0M,
Deposit = (decimal?)null,
Withdrawal = (decimal?)d.Amount,
Date = d.Date,
Account_Type = null,
Account_Holder_Tittle = null,
Account_Holder_FirstName = null,
Account_Holder_LastName = null
})).OrderBy(r => r.Date)
.Union(context.Current_Account_Details.Where(x => x.Account_Number == accountNumber).Select(e => new AccountTransaction
{
Account_Number = e.Account_Number,
Account_Balance = (decimal?)e.Account_Balance,
Deposit = (decimal?)0M,
Withdrawal = (decimal?)0M,
Date = e.Account_Creation_Date,
Account_Type=e.Account_Type,
Account_Holder_Tittle = null,
Account_Holder_FirstName =null,
Account_Holder_LastName = null
}))
.Union(context.Current_Account_Holder_Details.Where(x=>x.Account_Number ==accountNumber).Select(d=> new AccountTransaction
{
Account_Number = d.Account_Number,
Account_Balance = null,
Deposit =null,
Withdrawal = null,
Date = null,
Account_Type = null,
Account_Holder_Tittle =d.Tittle,
Account_Holder_FirstName=d.Account_Holder_First_Name,
Account_Holder_LastName=d.Account_Holder_Last_Name
}));
var js = new System.Web.Script.Serialization.JavaScriptSerializer();
return js.Serialize(inOut);
}
}
Hier ist der Code.

Hier ist der scrren Schuss, wenn ich die Anwendung ausführen.
