How to: Create a File in Visual Basic
This example creates an empty text file at the specified path using the Create method in the File class.
Example
Dim file As System.IO.FileStream
file = System.IO.File.Create("c:\test.txt")
Compiling the Code
Use the file variable to write to the file.
Robust Programming
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).
Security
A SecurityException may be thrown in partial-trust environments.
The call to the Create method requires FileIOPermission.
An UnauthorizedAccessException is thrown if the user does not have permission to create the file.
