附:写特定TXT格式数据的写入函数:
Private Sub SaveDataFile()
Try
If Dir.Exists(Application.StartupPath & "\DataFile") = False Then
Dir.CreateDirectory(Application.StartupPath & "\DataFile")
End If
If FileOutput Is Nothing Then
FileOutput = New FileStream(Application.StartupPath & "\DataFile\" & ItemStr & ".txt", FileMode.Create, FileAccess.Write)
End If
If BinaryOutput Is Nothing Then
BinaryOutput = New BinaryWriter(FileOutput)
End If
Dim i As Integer
Try
For i = 0 To ylist.Count - 1
FileOutput.Seek(i * 20, SeekOrigin.Begin)
BinaryOutput.Write(Convert.ToSingle(ylist(i)))
Next
Catch ex1 As FormatException
MsgBox(ex1.Message)
End Try
Catch ex2 As IOException
MsgBox(ex2.Message)
Catch ex As Exception
'MsgBox(ex.Message)
Finally
FileOutput.Close()
BinaryOutput.Close()
If (FileOutput Is Nothing) = False Then
FileOutput = Nothing
End If
If (BinaryOutput Is Nothing) = False Then
BinaryOutput = Nothing
End If
End Try
End Sub
此代码为边学边试, 写出来的. 在学的过程中,我一直有个问题想问:
如何能将一个一维数组直接写入EXCEL中的某一列中.为何非要用到二维数组来进行.
不明. 如有知道的朋友,请告之.
谢谢!
