VB.NET怎么將DataGridview里的內(nèi)容導出到EXCEL去

不好意思 現(xiàn)在才看到；Private Sub 導出EXCEL_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click

Dim xlApp, xlBook, xlSheet As Object

xlapp = CreateObject("Excel.Application")

xlbook = xlapp.Workbooks.Add

xlsheet = xlbook.Worksheets(1)

'Dim xlapp As New Excel.Application

vb中如何將數(shù)據(jù)導出到excel

介紹

下面通過一步一步的介紹，如何通過VB.NET來讀取數(shù)據(jù)，并且將數(shù)據(jù)導入到Excel中。

第一步：

打開VS開發(fā)工具，并且添加引用。

然后選擇。

Microsoft Excel 12.0 object library and。

Microsoft Excel 14.0 object library。

第二步：

創(chuàng)建一個Excle在你的電腦中。

第三步：

在VS中寫入如下代碼：

Imports System.Data

Imports System.Data.SqlClient

Imports Excel = Microsoft.Office.Interop.Excel。

Public Class excel

‘添加按鈕

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) _

? Handles Button1.Click

Try

?? ?'創(chuàng)建連接

?? ?Dim cnn As DataAccess = New DataAccess(CONNECTION_STRING)

?? ?

?? ?Dim i, j As Integer

?? ?'創(chuàng)建Excel對象

?? ?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

?? ?xlApp = New Microsoft.Office.Interop.Excel.ApplicationClass

?? ?xlWorkBook = xlApp.Workbooks.Add(misValue)

?? ?' 打開某一個表單

?? ?xlWorkSheet = xlWorkBook.Sheets("sheet1")

?? ?' sql查詢

?? ?'??xlWorkBook.Sheets.Select("A1:A2")

?? ?Dim sql As String = "SELECT * FROM EMP"

?? ?' SqlAdapter

?? ?Dim dscmd As New SqlDataAdapter(sql, cnn.ConnectionString)

?? ?' 定義數(shù)據(jù)集

?? ?Dim ds As New DataSet

?? ?dscmd.Fill(ds)

?? ? ‘添加字段信息到Excel表的第一行

?? ?xlWorkSheet.Cells(1, 1).Value = "First Name"

?? ?xlWorkSheet.Cells(1, 2).Value = "Last Name"

?? ?xlWorkSheet.Cells(1, 3).Value = "Full Name"

?? ?xlWorkSheet.Cells(1, 4).Value = "Salary"

?? ?' 將數(shù)據(jù)導入到excel

?? ???For i = 0 To ds.Tables(0).Rows.Count - 1

?? ?? ? 'Column

?? ?? ? For j = 0 To ds.Tables(0).Columns.Count - 1

?? ?? ?? ???' this i change to header line cells

?? ?? ?? ???xlWorkSheet.Cells(i + 3, j + 1) = _

?? ?? ?? ???ds.Tables(0).Rows(i).Item(j)

?? ?? ? Next

?? ?Next

?? ?'HardCode in Excel sheet

?? ?' this i change to footer line cells??

???xlWorkSheet.Cells(i + 3, 7) = "Total"

?? ?xlWorkSheet.Cells.Item(i + 3, 8) = "=SUM(H2:H18)"

?? ?' 保存到Excel

?? ?xlWorkSheet.SaveAs("D:\vbexcel.xlsx")

?? ?xlWorkBook.Close()

?? ?xlApp.Quit()

?? ?releaseObject(xlApp)

?? ?releaseObject(xlWorkBook)

?? ?releaseObject(xlWorkSheet)

?? ?'彈出對話框顯示保存后的路徑

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

Catch ex As Exception

End Try

End Sub

' Function of Realease Object in Excel Sheet

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

End Class

復制代碼。

第四步：

看到如下導出結果。
