试试这个：

Try this:

Private Sub Export_Button_Click(ByVal sender As System.Object, ByVal e As 
System.EventArgs) Handles VIEW_Button.Click

    Dim xlApp As Microsoft.Office.Interop.Excel.Application
    Dim xlWorkBook As Microsoft.Office.Interop.Excel.Workbook
    Dim xlWorkSheet As Microsoft.Office.Interop.Excel.Worksheet
    Dim misValue As Object = System.Reflection.Missing.Value
    Dim i As Integer
    Dim j As Integer

    xlApp = New Microsoft.Office.Interop.Excel.ApplicationClass
    xlWorkBook = xlApp.Workbooks.Add(misValue)
    xlWorkSheet = xlWorkBook.Sheets("sheet1")


    For i = 0 To DataGridView1.RowCount - 2
        For j = 0 To DataGridView1.ColumnCount - 1
            For k As Integer = 1 To DataGridView1.Columns.Count
                xlWorkSheet.Cells(1, k) = DataGridView1.Columns(k - 1).HeaderText
                xlWorkSheet.Cells(i + 2, j + 1) = DataGridView1(j, i).Value.ToString()
            Next
        Next
    Next

    xlWorkSheet.SaveAs("D:\vbexcel.xlsx")
    xlWorkBook.Close()
    xlApp.Quit()

    releaseObject(xlApp)
    releaseObject(xlWorkBook)
    releaseObject(xlWorkSheet)

    MsgBox("You can find the file D:\vbexcel.xlsx")
End Sub

Private Sub releaseObject(ByVal obj As Object)
    Try
        System.Runtime.InteropServices.Marshal.ReleaseComObject(obj)
        obj = Nothing
    Catch ex As Exception
        obj = Nothing
    Finally
        GC.Collect()
    End Try
End Sub
