Replace a File Using VB.NET
The Replace method replaces the contents of a specified file with the contents of another file. This method deletes the original file and creates a backup of the replaced file.
The following code snippet moves the contents of the original file into the replaced file and also creates a backup of the replaced file and deletes the original file.
Suppose we want to replace MaheshTXFITx.txt file with backup of MaheshTXFI.txt as MaheshTXFI.txt.bac. Before running below code file looks as:
Dim repFile As String = "C:\Temp\MaheshTXFI.txt"
Dim backupFile As String = "C:\Temp\MaheshTXFI.txt.bac"
Dim fileName As String = "C:\Temp\MaheshTXFITx.txt"
Dim fi As New IO.FileInfo(fileName)
fi.Replace(repFile, backupFile, False)
Catch iox As IOException
Run above code and see file is replaced.
