File.Create Method (String, Int32)
Creates or overwrites the specified file.
Assembly: mscorlib (in mscorlib.dll)
'Declaration Public Shared Function Create ( _ path As String, _ bufferSize As Integer _ ) As FileStream
- Type: System.String
The name of the file.
- Type: System.Int32
The number of bytes buffered for reads and writes to the file.
The caller does not have the required permission.
path specified a file that is read-only.
path is a zero-length string, contains only white space, or contains one or more invalid characters as defined by InvalidPathChars.
path is Nothing.
The specified path, file name, or both exceed the system-defined maximum length. For example, on Windows-based platforms, paths must be less than 248 characters, and file names must be less than 260 characters.
The specified path is invalid (for example, it is on an unmapped drive).
An I/O error occurred while creating the file.
path is in an invalid format.
The path parameter is permitted to specify relative or absolute path information. Relative path information is interpreted as relative to the current working directory. To obtain the current working directory, see GetCurrentDirectory.
This method is equivalent to the FileStream(String, FileMode, FileAccess, FileShare, Int32) constructor overload. If the specified file does not exist, it is created; if it does exist and it is not read-only, the contents are overwritten.
By default, full read/write access to new files is granted to all users. The file is opened with read/write access and must be closed before it can be opened by another application.

The following example creates a file with the specified buffer size.
Imports System Imports System.IO Imports System.Text Public Class Test Public Shared Sub Main() Dim path As String = "c:\temp\MyTest.txt" ' Delete the file if it exists. If File.Exists(path) Then File.Delete(path) End If ' Create the file. Dim fs As FileStream = File.Create(path, 1024) Dim info As Byte() = New UTF8Encoding(True).GetBytes("This is some text in the file.") ' Add some information to the file. fs.Write(info, 0, info.Length) fs.Close() ' Open the stream and read it back. Dim sr As StreamReader = File.OpenText(path) Do While sr.Peek() >= 0 Console.WriteLine(sr.ReadLine()) Loop sr.Close() End Sub End Class
