vb.net linq插入新记录

Question

我试图通过linq插入新记录。即时更新和读取数据没有任何问题。但我不知道如何插入一个新的记录。这是我的功能的开始。我知道它还没有完成。所有的帮助将会很好。

Public Function AddAddressInfo(ByVal objdeptGUID As String, ByVal objGEOCode As String, ByVal objArressCommonName As String, ByVal objStreetAddress As String, ByVal objAddressNotes As String, ByVal objIsPublic As Boolean, ByVal objSesionToken As String) 
    ''#Check of Token is good 
    If CheckToken(objSesionToken, objdeptGUID) = False Then 
     Return "Error" 
    End If 

    Try 
     Dim lqAlarms As New linqAlarmDumpDataContext 
     Dim AddInfo = From r In lqAlarms.tbAddressInfos 
         Where r.DeptGUID = objdeptGUID 
         Select r 
    Catch ex As Exception 

    End Try 
End Function 

Answer 1

使用InsertOnSubmit()和SubmitChanges()插入记录。

Dim lqAlarms As New linqAlarmDumpDataContext 
Dim info As New tbAddressInfo With { ... } ' Create the record 
lqAlarms.tbAddressInfos.InsertOnSubmit(info) ' Insert the record 
lqAlarms.SubmitChanges()      ' Commit the insertion
