How to: Create a File in Visual Basic
Imports System Imports System.IO Imports System.Text Module Module1 Sub Main() Dim path As String = "c:\temp\MyTest.txt" ' Create or overwrite the file. Dim fs As FileStream = File.Create(path) ' Add text to the file. Dim info As Byte() = New UTF8Encoding(True).GetBytes("This is some text in the file.") fs.Write(info, 0, info.Length) fs.Close() End Sub End Module
Compiling the Code
Use the file variable to write to the file.
If the file already exists, it is replaced.
The following conditions may cause an exception:
The path name is malformed. For example, it contains illegal characters or is only white space (ArgumentException).
The path is read-only (IOException).
The path name is Nothing (ArgumentNullException).
The path name is too long (PathTooLongException).
The path is invalid (DirectoryNotFoundException).
The path is only a colon ":" (NotSupportedException).
