VB.net小技巧——使用DataGridView显示EXECL表格内容

当前位置:

直接上代码

Private Sub Button24_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button24.Click

Dim fileDialog As OpenFileDialog = New OpenFileDialog()

fileDialog.InitialDirectory = My.Computer.FileSystem.CurrentDirectory

fileDialog.Filter = "Excel files(*.xls)|*.xls|Excel files(*.xlsx)|*.xlsx"

fileDialog.FilterIndex = 1

fileDialog.RestoreDirectory = True

If fileDialog.ShowDialog() = Windows.Forms.DialogResult.OK Then

Dim fileName As String

Dim strConn As String

fileName = fileDialog.FileName

'建立EXCEL连接, 读入数据

If fileDialog.FilterIndex = 1 Then

strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source='" & fileName & "';Extended Properties=Excel 8.0;"

Else

strConn = "Provider=Microsoft.Ace.OLEDB.12.0;Data Source='" & fileName & "';Extended Properties=Excel 8.0;"

End If

Dim myDataset As New DataSet

Dim da As New OleDb.OleDbDataAdapter("select * FROM [Sheet1$]", strConn)

Dim bindin As BindingSource = New BindingSource

Try

DataGridView1.Columns.Clear()

da.Fill(myDataset)

bindin.DataSource = myDataset.Tables(0)

DataGridView1.DataSource = bindin.DataSource

Catch ex As Exception

MessageBox.Show("EXECL文件载入失败")

End Try

End If

End Sub

其中

例如有一个这样的execl文档

载入后：

行和列都是从0数字开始。

DataGridView1.Rows(0).Cells(0).Value = 0000008

DataGridView1.Rows(0).Cells(3).Value 是空白，可以写入数值进去

以上的例子是可以对接收到的协议数据进行地址辨别后，自动将相应的值填入表格中，不需要每次人为触发查询，且自动将原始数据进行公式换算后显示，非常的方便。
