Question

请帮助我修复代码以联接2个表，但2个相等。我有2个表格（交易和Chartaccount）

Chartaccount Table
+---------+--------+
|KodeAkun |NamaAkun|
+---------+--------+
|10000    |Asset   |
|20000    |Expense |
|30000    |Revenue |
+------------------+

Transaction Table
+---------+--------+---------+-------+
|KodeAkunD| DEBIT  |KodeAkunK|KREDIT |
+---------+--------+---------+-------+
|10000    |10000   |20000    |0      |
+------------------+---------+-------+

在我的模型中

Chartaccount Model
public string KodeAkun {get; set;}
public string NamaAkun {get; set;}
public decimal Saldo {get; set;}

Transaction Model
public string KodeAkunD {get; set;}
public string KodeAkunK {get; set;}
public decimal Debit {get; set;}
public decimal Kredit {get; set;}
public string Keterangan {get; set;}

在我的控制器中

public IActionResult Index()
{
var transaction1 = from p in _context.Transaction join k in _context.ChartAccount on p.KodeakunD equals k.Kodeakun
                           select new Transaction {
                           KodeakunD = p.KodeakunD + k.Namaakun,
                           KodeakunK = p.KodeakunK + k.Namaakun};          
return View(transaction1);
}

目前在我看来

+-----------+--------+----------+-------+-------------------+
|KodeAkunD  | DEBIT  |KodeAkunK |KREDIT |Action             |
+-----------+--------+----------+-------+-------------------+
|10000Asset |10000   |20000Asset|0      |Edit,Details,Delete|
+-----------+--------+----------+-------+-------------------+

我想要什么

+-----------+--------+------------+-------+-------------------+
|KodeAkunD  | DEBIT  |KodeAkunK   |KREDIT |Action             |
+-----------+--------+------------+-------+-------------------+
|10000Asset |10000   |20000Expense|0      |Edit,Details,Delete|
+-----------+--------+------------+-------+-------------------+

而且，如果我加入控制器，我的操作将无法正确路由，如果我单击我的操作，它将返回404

您的问题在这一行

KodeakunK = p.KodeakunK + k.Namaakun

p.KodeakunK = 2000，但是您在p.KodeakunD上连接了表，p.KodeakunD是1000的连接线，导致“资产”。

您需要分别通过Chartaccount加入KodeakunK和KodeakunD。您可以选择两个不同的联接，也可以使用linq多个联接。
