VB.NET怎么将DataGridview里的内容导出到EXCEL去

不好意思 现在才看到；Private Sub 导出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

'Dim xlbook As Excel.Workbook

'Dim xlsheet As Excel.Worksheet

Dim rowindex, colindex As Integer rowindex = 1 '行

colindex = 0 '列

'xlbook = xlapp.Workbooks.Open("c:\EXCEL.xls") '打开EXCEL文件

xlsheet = xlapp.Worksheets("sheet1") '打开sheet1那页 Dim a As New DataSet

Dim table As New System.Data.DataTable table = DataSet11.Tables("INVMATLISTA") '填充表 Dim row As DataRow '定义row为表格的行

Dim col As DataColumn '定义col为表格的列 '把表格的每一列写到EXCEL去

For Each col In table.Columns

colindex = colindex + 1

xlapp.Cells(1, colindex) = col.ColumnName Next

'把表格的每一行写到EXCEL去

For Each row In table.Rows

rowindex = rowindex + 1

colindex = 0

For Each col In table.Columns

colindex = colindex + 1

xlapp.Cells(rowindex, colindex) = row(col.ColumnName)

Next

Next

xlapp.Visible = True

End Sub 前提要先引用一个Microsoft.Office.Interop.Excel.dll然后在最上面先输入Imports Microsoft.Office.Interop； 就可以了

vb中如何将数据导出到excel

介绍

下面通过一步一步的介绍，如何通过VB.NET来读取数据，并且将数据导入到Excel中。

第一步：

打开VS开发工具，并且添加引用。

然后选择。

Microsoft Excel 12.0 object library and。

Microsoft Excel 14.0 object library。

第二步：

创建一个Excle在你的电脑中。

第三步：

在VS中写入如下代码：

Imports System.Data

Imports System.Data.SqlClient

Imports Excel = Microsoft.Office.Interop.Excel。

Public Class excel

‘添加按钮

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

  Handles Button1.Click

Try

    '创建连接

    Dim cnn As DataAccess = New DataAccess(CONNECTION_STRING)

    

    Dim i, j As Integer

    '创建Excel对象

    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)

    ' 打开某一个表单

    xlWorkSheet = xlWorkBook.Sheets("sheet1")

    ' sql查询

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

    Dim sql As String = "SELECT * FROM EMP"

    ' SqlAdapter

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

    ' 定义数据集

    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"

    ' 将数据导入到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)

    '弹出对话框显示保存后的路径

    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

复制代码。

第四步：

看到如下导出结果。
