嗨

Hi
I am doing a vs2008 smart device project for windows ce device. and i want to export the data to a csv file, when i do the transfer data i get an error.
I have attached my code,please give your suggestions
Private Sub BtnAvaStk_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnTransData.Click
Using cmd As New SqlCeCommand("SELECT * FROM ItemMaster")
Using sda As New SqlCeDataAdapter()
cmd.Connection = con
sda.SelectCommand = cmd
Using dt As New DataTable()
sda.Fill(dt)
'Build the CSV file data as a Comma separated string.
Dim csv As String = String.Empty
For Each column As DataColumn In dt.Columns
'Add the Header row for CSV file.
csv += column.ColumnName + ","c
Next
'Add new line.
csv += vbCr & vbLf
For Each row As DataRow In dt.Rows
For Each column As DataColumn In dt.Columns
'Add the Data rows.
csv += row(column.ColumnName).ToString().Replace(",", ";") + ","c
Next
'Add new line.
csv += vbCr & vbLf
Next
Dim folderPath As String = "F:\CSV\DataGridViewExport.csv"
File.WriteAllText(folderPath, csv)
'' File.OpenWrite(folderPath, csv)
End Using
End Using
End Using
''End Using
End Sub
我的尝试:
在.writealltext中执行错误时显示
并显示为.writealltext不是system.io.file的成员
What I have tried:
while executing error in .writealltext and showing as .writealltext is not a member of system.io.file

***不允许评论此时
您需要使用StreamWriter将数据写出来。
