Question

我有几个输入框，我想将所有这些值存储在二维数组中，然后将所有值写入txt文件，这是因为我想知道值的i，j。所以，如果我进行一些更改，我只会看看这个数组，那么如何在txt文件中插入一个数组呢？

我在做

Dim mArray(100,100) As String

mArray(0,0) = Textbox1.Text
mArray(0,1) = Textbox2.Text
...



Dim objWriter As New System.IO.StreamWriter("c:\file.txt", False)
objWriter.WriteLine(mArray)
objWriter.Close()

或者做得更好：

Dim objWriter As New System.IO.StreamWriter("c:\file.txt", False)
objWriter.WriteLine(Textbox1.Text)
objWriter.WriteLine(Textbox2.Text)
objWriter.WriteLine(Textbox3.Text)
objWriter.WriteLine(Textbox4.Text)
...
objWriter.WriteLine(Textboxn.Text)

objWriter.Close()

我不知道二维数组，但对于单维数组，这里是代码：

Dim mArray(100) as string
mArray(0) = TextBox1.Text
.
.
.
.

For I as integer = 0 to mArray.count - 1
    Dim objWriter As New System.IO.StreamWriter("c:\file.txt", False)
    objWriter.WriteLine(mArray(I))
    objWriter.Close()
Next I

我认为对于二维数组，你需要使用嵌套的

For I as integer = 0 to ...........
    For J as integer = 0 to ..........
        Dim objWriter As New System.IO.StreamWriter("c:\file.txt", False)
        objWriter.WriteLine(mArray(I,J))
        objWriter.Close()
    Next J
next I

保存txt文件中输入框的二维数组值的最佳方法
