# Line Input# Statement

Reads a line from a sequential file into a variable.

### Syntax:

    Line Input #fileNum, variable

### Parameters:

fileNum: Number of the file that contains the data that you want to read. The file must have been opened in advance with the Open statement using the key word INPUT.

variable: The name of the variable that stores the result.

使用 Line Input# 陳述式，您可以從開啟的檔案讀取字串，並將其寫入一個變數中。字串型變數的逐行讀取程序在遇到第一個斷行鍵 (Asc=13) 或斷行 (Asc=10) 時停止。結果字串中不包含行尾標記。

### Example:

    Sub ExampleWorkWithAFile
    Dim iNumber As Integer
    Dim sLine As String
    Dim aFile As String
    Dim sMsg As String
        aFile = "c:\data.txt"
        iNumber = Freefile
        Open aFile For Output As #iNumber
        Print #iNumber, "This is a line of text"
        Print #iNumber, "This is another line of text"
        Close #iNumber
        iNumber = Freefile
        Open aFile For Input As iNumber
        While Not eof(iNumber)
            Line Input #iNumber, sLine
            If sLine <>"" Then
                sMsg = sMsg & sLine & chr(13)
            End If
        Wend
        Close #iNumber
        MsgBox sMsg
    End Sub
