Create or open the sub statement you want to use to write your array to a file. For example:

Private Sub WriteArray()

This creates a new sub statement that you may call anytime in your program.

Declare your StreamWriter object with the following line:

Dim writer As System.IO.StreamWriter = New System.IO.StreamWriter("path_to_file", True)

Replace the quoted string with the actual path to the file you will use to save the array. For example, "C:\myFile.txt" uses a text file in the C:\ folder. The second parameter is a Boolean value used to determine what you want to happen if the file already exists. "True" means you want to append to an existing file while "False" means you want to overwrite it. If no file exists, VB will automatically create it.

Use a loop to write the contents of your array to the file:

For i = 0 To sizeOfArray

writer.Write(myArray(i))

writer.WriteLine()

Next i

The "Write" sub writes a character to the file. In the case of your array, it will write the entire contents of each array index, specified by the counter "i." The "WriteLine" sub simply writes a new line to the file to keep each array value separate.

Close the StreamWriter object and the sub statement with the following:

writer.Close()

End Sub
