linq - 如何将此 sql 查询更改为 linq to sql？

Question

我写了查询，我想将其转换为 linq 查询

SELECT     dbo.tblSaman.fldSamanId, dbo.tblFaaliatSaman.FldFaaliatId
FROM         dbo.tblSaman LEFT OUTER JOIN
                  dbo.tblFaaliatSaman ON dbo.tblSaman.fldSamanId = dbo.tblFaaliatSaman.fldSamanId
WHERE     (dbo.tblFaaliatSaman.FldFaaliatId IN (3, 4))

Answer 1

尝试使用类似的东西：

int[] ids = { 3, 4 };
            var items = context.tblSaman.Join(context.tblFaaliatSaman.DefaultIfEmpty().Where(x => ids.Contains(x.FldFaaliatId)), x => x.fldSamanId,
                                  y => y.fldSamanId, (x, y) => new { fldSamanId = x.fldSamanId, FldFaaliatId = y.FldFaaliatId });
