如何循環扔在vb.net windows應用程序

Question

我有一個數據網格view..in更新按鈕，我寫這樣的

Dim cid As Integer 
     Dim dtid As Integer 
     Dim cmpname As String 
     Dim dtname As String 
     Dim dtPhone As String 
     Dim dtEmail As String 
Dim rv = DirectCast(bSource.Current, DataRowView) 
     cid = rv.Row.Field(Of Integer)("Cid") 
     dtid = rv.Row.Field(Of Integer)("dtId") 
     cmpname = rv.Row.Field(Of String)("CompanyName") 
     dtname = rv.Row.Field(Of String)("dtName") 
     dtPhone = rv.Row.Field(Of String)("dtPhone") 
     dtEmail = rv.Row.Field(Of String)("dtEmail") 
adapter.UpdateCommand = New SqlCommand("UPDATE CompanyMaster_tbl SET CompanyName = @CompanyName", con) 
     adapter.UpdateCommand = New SqlCommand("update DepartmentMaster_tbl set dtName = @dtName,dtPhone = @dtPhone,dtEmail = @dtEmail where dtId=@dtid", con) 
     adapter.UpdateCommand.Parameters.AddWithValue("@Cid", cid) 
     adapter.UpdateCommand.Parameters.AddWithValue("@CompanyName", cmpname) 
     adapter.UpdateCommand.Parameters.AddWithValue("@dtId", dtid) 
     adapter.UpdateCommand.Parameters.AddWithValue("@dtName", dtname) 
     adapter.UpdateCommand.Parameters.AddWithValue("@dtPhone", dtPhone) 
     adapter.UpdateCommand.Parameters.AddWithValue("@dtEmail", dtEmail) 
     adapter.UpdateCommand.ExecuteNonQuery() 

我在datagridview.same新的代碼在數據網格視圖中的所有行時間如果我更新多行，它影響最後更新的行,,所以我需要循環拋出datagridview中的所有行..如何我可以實現的..

所以我給了這樣的循環內的整個代碼

For Each row As DataGridViewRow In gv.Rows 
    'my code here 
Next 

，但隨後還更新最後更新的行？在此先感謝

Answer 1

For Each row As DataGridViewRow In gv.Rows 
Cmd = new Sqlcommand("insert into tblemp (empid,empval) values("& rw.cells(0).value &",'"& rw.cells(1).value&"')",con) 
Next 

Answer 2

嘗試使用「行」，而不是電流：

For Each row As DataGridViewRow In gv.Rows 
     ... 
     adapter.UpdateCommand.Parameters.AddWithValue("@Cid", Row.Cells("cid").Value) 
     ... 
     adapter.UpdateCommand.ExecuteNonQuery() 
    Next
