如何在Vb.net中创建动态Linq to SQL

我有内联和动态SQL查询，例如

I have inline and dynamic SQL query like

Dim SQL as string ="sSelect" & Top & "i1.f1,i2.f2" & sselect & 
"from table1 i1 inner join table i2 on i1.eventseriesID=i2.eventseriesID " & Sjoin &
& " where i1.binheritseries=1 "

if where <>"" then
SQL &="order By" & OrderBy
End if

在这个Top，sjoin中，Sjoin是额外选择的字段，字段和其他连续的Join。

现在我希望这个查询作为LINQ使用dbml文件与正确的表关联和字符串表达式linq.I试图获得帮助来自以上链接
