Question

我的代码如下

GetDairyHeaderInfoByEmail(id)
    .Where(p => p.ATTRIBUTE15 == id)
    .Select(jk=> new {
        jk.HEADER_ID_PK,
        jk.VENDOR_ID,
        jk.VENDOR_SITE_ID,
        jk.VENDOR_NAME,
        jk.ADDRESS_LINE1,
        jk.ATTRIBUTE15
    })
    .GroupBy(p => p.HEADER_ID_PK)
    .Select(p => new {
        header_id_pk = p.Key,
        invoice_id_pk = _ippDetailServices.GetDairyHeaderInfoByEmail(id).Where(k => k.HEADER_ID_PK == p.Key).Select(c => new { c.APP_INVOICES_ID_PK, c.INVOICE_TYPES, c.IS_HOURLY }).ToList() }).ToList();

我看到的结果如下

[{ “header_id_pk”：800.0，

"invoice_id_pk": [
  {
    "APP_INVOICES_ID_PK": 1058.0,
    "INVOICE_TYPES": "EPP",
    "IS_HOURLY": "Y"
  },
  {
    "APP_INVOICES_ID_PK": 1059.0,
    "INVOICE_TYPES": "CPP",
    "IS_HOURLY": "Y"
  },
  {
    "APP_INVOICES_ID_PK": 1060.0,
    "INVOICE_TYPES": "WHT ON DIVIDEND",
    "IS_HOURLY": "N"
  },
  {
    "APP_INVOICES_ID_PK": 1061.0,
    "INVOICE_TYPES": "L.P",
    "IS_HOURLY": "N"
  }      
]   } ]

但我希望结果如下

[{

"header_id_pk": 800.0,
"HEADER_ID_PK" : 800.0,
"VENDOR_ID" : 12.0,
"VENDOR_SITE_ID" : 33.0,
"VENDOR_NAME" : Faisal,
"ADDRESS_LINE1" : XYZ address,
"invoice_id_pk": [
  {
    "APP_INVOICES_ID_PK": 1058.0,
    "INVOICE_TYPES": "EPP",
    "IS_HOURLY": "Y"
  },
  {
    "APP_INVOICES_ID_PK": 1059.0,
    "INVOICE_TYPES": "CPP",
    "IS_HOURLY": "Y"
  },
  {
    "APP_INVOICES_ID_PK": 1060.0,
    "INVOICE_TYPES": "WHT ON DIVIDEND",
    "IS_HOURLY": "N"
  },
  {
    "APP_INVOICES_ID_PK": 1061.0,
    "INVOICE_TYPES": "L.P",
    "IS_HOURLY": "N"
  }      
]   } ]

对于乱七八糟的遗憾，这是我的第一个问题。感谢

var dairy = _ippDetailServices.GetDairyHeaderInfoByEmail(id).Where(p => 
p.ATTRIBUTE15 == id).Select(jk=> new { jk.HEADER_ID_PK, 
jk.VENDOR_ID, 
jk.VENDOR_SITE_ID, 
jk.VENDOR_NAME, 
jk.ADDRESS_LINE1, 
jk.ATTRIBUTE15 
}).GroupBy(p => new { p.HEADER_ID_PK, 
p.VENDOR_ID, p.VENDOR_SITE_ID, 
p.VENDOR_NAME, p.ADDRESS_LINE1, 
p.ATTRIBUTE15 }).Select(p => new { 
header_id_pk = p.Key, invoice_id_pk = 
_ippDetailServices.GetDairyHeaderInfoByEmail(id).Where(k => k.HEADER_ID_PK == 
p.Key.HEADER_ID_PK).Select(c => new { c.APP_INVOICES_ID_PK, 
c.INVOICE_TYPES, 
c.IS_HOURLY }).ToList() }).ToList();

我想通了，我只需要在Group By子句中添加这些主列。
