【求助】怎样往文本文件中写入数组数据？

[luckyunfei]

程序里生成的数组是动态改变的，现在我想写到文本文件中去，想要得到格式如下:

a11 a12 a13 … a1n
a21 a22 a23 … a2n
… … … … …
am1 am2 am3 … amn

其实就是一个矩阵，m和n每次是不一样的，
程序中的数组是a（m，n）
请问如何做。

Option Explicit

Private Sub Command1_Click()
Dim M As Long
Dim N As Long
Dim OutStr As String
Dim A() As String

'............................

For M = 0 To UBound(A, 1)
For N = 0 To UBound(A, 2)
OutStr = A(M, N) & OutStr & Chr(vbKeyTab)
Next
OutStr = OutStr & Chr(13)
Next
WritTextFile "C:\DEMO.TXT", OutStr
End Sub

'
'写TEXT文件
'函数:WritTextFile
'参数:FileName 目标文件名.WritStr 写到目标的字符串.
'返回值:成功 返回文件内容.失败 返回""
'注:如果同名,目标字符串将覆盖原文件内容.
Public Function WritTextFile(Filename As String, WritStr As String) As Boolean
'/保存文件
Dim FileID As Long, ConTents As String
Dim A As Long, B As Long

On Error Resume Next

FileID = FreeFile
Open Filename For Output As #FileID
Print #FileID, WritStr
Close #FileID
WritTextFile = (Err.Number = 0)
Err.Clear
End Function
