返回匿名linq连接中的所有列

Question

如何返回以下匿名linq join中的所有列：

var results = (from t in Table1.AsEnumerable() join t2 in Table2.AsEnumerable()
                on t.Field<string>("id") equals t2.Field<string>("id")
                into allcol from rows in allcol
                select rows);

我从Table2获取允许行，而Table1

没有行

Answer 1

var results = (from t in Table1.AsEnumerable() 
                           join t2 in Table2.AsEnumerable()
                           on t.Field<string>("id")
                           equals t2.Field<string>("id")
                           into allcol
                           from rows in allcol
                           select new {table1=t,table2=rows});

我希望这会有所帮助。
