I h开发者_开发技巧ave a VB.net program that I have reading a text file, what is the best way to put the text file into VB to be able to check if a string is on one of the lines in a text file, sample code would be helpful.
Dim fileText as string = My.Computer.FileSystem.ReadAllText("c:\AnyFile.txt")
And to check whether a specific line is present in the string, use the Contains
method :)
Contains method on MSDN
It might be easier to read the file as an array of strings rather then one lump string, if your doing alot of per line comparisions.
See the MSDN reference to the System.IO.File class.

System.IO.File.ReadAllLines

Dim fileLines() as string = System.IO.File.ReadAllLines("c:\AnyFile.txt")
