查詢文本文件

Question

嘿，有沒有什麼方法可以用OleDB或其他方式查詢文本文件。只需要能夠像下面查詢它：

Dim connectionString As String 
    connectionString = "Provider=?????????????????;Data Source=C:\Data\theFile.txt" 
    connection = New System.Data.OleDb.OleDbConnection(connectionString) 
    connection.Open() 

    Dim sqlString As String 
    sqlString = "SELECT * FROM Categories" 
    Dim command As New System.Data.OleDb.OleDbCommand(sqlString, connection) 
    'Retrieve data 
    reader = command.ExecuteReader() 

任何幫助將是偉大的！

請嘗試這樣。

con = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|;Extended properties='text;HRD=yes;FMT=Delimited'")
