Question

我正在将wcf rest服务用于angular js application.I我试图通过Wcf Rest Service显示来自sql数据库的数据。我正在使用Union函数来连接多表记录。我想在将帐户输入到输入字段时将帐户信息显示到网页中，然后单击提交按钮，但问题是它不是必需的数据..

这是班级。

public class AccountTransaction
    {
        public int? Account_Number { get; set; }

        public decimal? Deposit { get; set; }

        public decimal? Withdrawal { get; set; }

        public decimal? Account_Balance { get; set; }
        public string  Account_Type { get; set; }
        public string Account_Holder_Tittle { get; set; }
        public string Account_Holder_FirstName { get; set; }
        public string Account_Holder_LastName { get; set; }
        public string Date { get; set; }

    }

以下是方法实施。

 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);
            }
        }

Answer 1

我无法看到您在哪里显示帐户标签？您只显示这些列

            <th> Account Number</th>
            <th> Money In</th>
            <th>Date</th>
            <th> Money Out</th>
            <th>Date</th>
