如何使用vb.net将datagridview导出到excel？

我在vb.net中有一个datagridview,它从数据库中填充.我研究过,我发现没有内置的支持直接从datagridview打印.我不想使用水晶报告,因为我不熟悉它.

我打算将它导出到excel以使我能够从datagridview生成报告.

你能告诉我这样做的方法吗？

下面的代码创建Excel文件并将其保存在D：驱动器中
它使用Microsoft Office 2007

首先将READ REIDRANCE(Microsoft Office 12.0对象库)添加到您的项目中

然后将下面给出的代码添加到导出按钮单击事件 –

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
