BitConverter.IsLittleEndian Field

Indicates the byte order ("endianness") in which data is stored in this computer architecture.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public static readonly bool IsLittleEndian

This value is true if the architecture is little-endian; false if it is big-endian.

Different computer architectures store data using different byte orders. "Big-endian" means the most significant byte is on the left end of a word. "Little-endian" means the most significant byte is on the right end of a word.

The following code example illustrates the use of the IsLittleEndian field.

// Example of the BitConverter.IsLittleEndian field. 
using System;

class LittleEndDemo
{
    public static void Main( )
    {
        Console.WriteLine( 
            "This example of the BitConverter.IsLittleEndian field " +
            "generates \nthe following output when run on " +
            "x86-class computers.\n");
        Console.WriteLine( "IsLittleEndian:  {0}", 
            BitConverter.IsLittleEndian );
    }
}
