VB.NET怎么将DataGridview里的内容导出到EXCEL去

能给个源码吗

Answer 1

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
