Reads a line from a sequential file into a variable.

语法:

Line Input Statement diagram


Line Input #fileNum, variable

参数:

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#」语句，可以从打开的文件中读取字符串并将它写入一个变量。逐行读取字符串变量的过程在遇到第一个回车 (Asc=13) 或换行 (Asc=10) 时停止。得到的字符串中不包括行尾标记。

示例:


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
