如何在linq的select语句中使用where子句.(即在财产上.)

Question

我有这个linq查询:

var sku = (from a in con.MagentoStockBalances
           join b in con.MFGParts on a.SKU equals b.mfgPartKey
           join c in con.DCInventory_Currents on b.mfgPartKey equals c.mfgPartKey
           where a.SKU != 0 && c.dcKey ==6
           select new
           {
               Part_Number = b.mfgPartNumber,
               Stock = a.stockBalance,
               Recomended = a.RecomendedStock,
               Cato = c.totalOnHandQuantity
           }).ToList();

现在我需要删除c.dcKey == 6条件并具有以下内容:

var sku = (from a in con.MagentoStockBalances
           join b in con.MFGParts on a.SKU equals b.mfgPartKey
           join c in con.DCInventory_Currents on b.mfgPartKey equals c.mfgPartKey
           where a.SKU != 0
           select new
           {
               Part_Number = b.mfgPartNumber,
               Stock = a.stockBalance,
               Recomended = a.RecomendedStock,
               Cato = c.totalOnHandQuantity where c.dcKey == 6,
              Kerry = c.totalOnHandQuantity where c.dcKey == 7
           }).ToList();

Answer 1

像这样的东西:

Cato = c.dcKey == 6 ? c.totalOnHandQuantity : 0,
Kerry = c.dcKey == 7 ? c.totalOnHandQuantity : 0

？:语法称为条件运算符.
