带阵列的Linq

引发异常“对象引用未设置为对象的实例。”。。。但如果我移除

Dim Cozinhas as string = "1, 2, 3"
Dim FiltroCozinha() As String = Cozinhas.Split(",")

Dim Empresas = (From E In lstEmpresas _
                Group Join CE In lstCozinhasEmpresas On CE.EmpresaID Equals E.EmpresaID Into CEJ = Group From CE In CEJ.DefaultIfEmpty() _
                Group Join FC In lstFiltroCozinha On FC Equals CE.CozinhaID Into FCJ = Group From FC In FCJ.DefaultIfEmpty() _
                Select New With {E.Nome} _
               ).Distinct.ToList

它起作用了。如何左键连接数组“filterocozinha”

我认为您在同一行中声明并使用了相同的变量

对不起，我简化了代码……考虑对象的其他名称…DimeEppSist=（来自e中的新Bo.EpSimaE）.Stand（…）……问题继续！所以你确信<代码> LSTEMPRASAS 不是<代码>没有< /代码>吗？

                Group Join FC In lstFiltroCozinha On FC Equals CE.CozinhaID Into FCJ = Group From FC In FCJ.DefaultIfEmpty() _
