NET programming tutorial. For example, you can write an object of type Int32 and the BinaryWriter will write a 4-byte signed integer to a stream and advance the Position property of the stream by four bytes.

The following code example demonstrates how to store and retrieve application settings in a file. Add the following code.

Boolean showStatusBar;. Boolean get. Console::WriteLine "Creating default application settings Console::WriteLine "If file not empty, read the app Using default values Console::WriteLine "Create a file and store the app settings Console::WriteLine "Loading app settings Console::WriteLine "Changing the settings Console::WriteLine "Saving the new settings Build and run the project.

The following is an output example. Create a new console application project and add the following code. WriteLine ;. ToString ,. LookupDir, appSettings. WriteLine "Change the application settings WriteLine "Save the settings Close ;. WriteLine "Creating a default application settings Exists fileName. Open fileName, FileMode. Open ;. Read 4 bytes into a buffer to. Read testArray, 0, 3 ;.

ReadSingle ;. ReadString ;. ReadInt32 ;. ReadBoolean ;. Using default values. Name ;. WriteLine "Creating a file and store the application settings Write aspectRatio ;. Write lookupDir ;. Write autoSaveTime ;. Write showStatusBar ;. An output sample:. Create a new empty project and you can use the solution and project name as shown in the following Figure.

Add a new class to the project as shown below. Imports Microsoft. Imports System. Public Class Test. Shared Sub Main. WriteLine "Change application settings End Sub. End Class. Public Class AppSettings. Dim aspRatio As Single. Dim lkupDir As String. Dim saveTime As Integer. Dim statusBar As Boolean. Property AspectRatio As Single.

Return aspRatio. End Get. Set ByVal value As Single. End Set. End Property. Property LookupDir As String. Return lkupDir. Set ByVal value As String. Return saveTime. Set ByVal value As Integer. Return statusBar. Set ByVal value As Boolean. Sub New.

If File. Exists fileName Then. Read testArray, 0, 3. End If. End Try. Sub Close. WriteLine "Create a file and store the application settings Write aspRatio. Write lkupDir. Write saveTime. Write statusBar. Or you can use the short cut button. IO; using System. IO Imports System.

How to use C# BinaryReader Class

Note: Visual Studio can open binary files and you can look at the data. It won't be readable, but it gives you an idea what is happening. Here: The file here is 48 bytes, because 12 integers of 4 bytes each are in it. Here we open the same binary file and then read in the bytes. BinaryReader here provides some useful properties that make this easier. When you run the next program, you will see all the ints recovered. This is returned by File.
