1.添加引用
添加引用->Com->Microsoft Excel 9.0 Object Library(对应Excel2000)
*Microsoft Excel 11.0 Object Library(对应Excel2003)
2.新建对象
实例化 Dim myExcel as New Excel.Application()
添加工作簿 myExcel.Workbooks.Add()
打开工作簿 myExcel.Workbooks.Open("FileName as String")
添加工作表 myExcel.Worksheets.Add()
单元格的值 myExcel.Worksheets(1).Cells(1, 1).Value
*所有元素集合的下标均是以1开始
3.保存关闭
保存工作簿 myExcel.Workbooks(1).Save() ‘1为指定索引
另存为 myExcel.Workbooks(1).SaveAs("FileName as String")
关闭工作簿 myExcel.Workbooks.close()
对象退出 myExcel.quit()
*务必先关闭工作簿后再退出Excel
4.实用程序
1.导入Excel到自定义数据类型
自定义数据类型
Structure DataStructure Dim HeadString As String Dim Data(,) As String End Structure
导入Excel
Dim TotalData() As DataStructure Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim myExcel As New Excel.Application Dim myWorkSheet1 As Excel.Worksheet Dim RowLength As Integer = 10 ‘读入数据的行数 Dim ColLength As Integer = 10 ‘读入数据的列数 myExcel.Workbooks.Open("C:\Users\temp.xls") ReDim TotalData(myExcel.Worksheets.Count - 1) For c = 1 To TotalData.Length myWorkSheet1 = myExcel.Worksheets(c) Dim tempString(RowLength - 1, ColLength - 1) As String For i = 0 To RowLength - 1 For j = 0 To ColLength - 1 tempString(i, j) = myWorkSheet1.Cells(i + 1, j + 1).value Next Next TotalData(c - 1).Data = tempString TotalData(c - 1).HeadString = myExcel.Workbooks(1).Worksheets(c).name Next myExcel.Workbooks.Close() myExcel.Quit() End Sub
2.导入自定义类型数据到ListView
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Dim RowLength As Integer = 10 ‘读入数据的行数 Dim ColLength As Integer = 10 ‘读入数据的列数 Dim SelectedIndex As Integer = 0 ‘工作表索引 Dim DataString(RowLength - 1, ColLength - 1) As String DataString = TotalData(SelectedIndex).Data ListView1.Clear() For j = 0 To ColLength - 1 ListView1.Columns.Add(DataString(0, j)) Next For i = 1 To RowLength - 1 ListView1.Items.Add(DataString(i, 0)) For j = 1 To 14 ListView1.Items(ListView1.Items.Count - 1).SubItems.Add(DataString(i, j)) Next Next End Sub
