BitConverter.GetBytes Method (UInt32)

Returns the specified 32-bit unsigned integer value as an array of bytes.

This API is not CLS-compliant. 

Namespace:  System
Assemblies:   System.Runtime.Extensions (in System.Runtime.Extensions.dll)
  mscorlib (in mscorlib.dll)

[CLSCompliantAttribute(false)]
public static byte[] GetBytes(
	uint value
)

Parameters

value
Type: System.UInt32

The number to convert.

Return Value

Type: System.Byte[]
An array of bytes with length 4.

The order of bytes in the array returned by the GetBytes method depends on whether the computer architecture is little-endian or big-endian.

The following code example converts the bit patterns of UInt32 values to Byte arrays with the GetBytes method.

// Example of the BitConverter.GetBytes( uint ) method. 
using System;

class GetBytesUInt32Demo
{
    const string formatter = "{0,16}{1,20}";

    // Convert a uint argument to a byte array and display it. 
    public static void GetBytesUInt32( uint argument )
    {
        byte[ ] byteArray = BitConverter.GetBytes( argument );
        Console.WriteLine( formatter, argument, 
            BitConverter.ToString( byteArray ) );
    }

    public static void Main( )
    {
        Console.WriteLine( 
            "This example of the BitConverter.GetBytes( uint ) " +
            "\nmethod generates the following output.\n" );
        Console.WriteLine( formatter, "uint", "byte array" );
        Console.WriteLine( formatter, "----", "----------" );

        // Convert uint values and display the results.
        GetBytesUInt32( 15 );
        GetBytesUInt32( 1023 );
        GetBytesUInt32( 0x100000 );
        GetBytesUInt32( 1000000000 );
        GetBytesUInt32( uint.MinValue );
        GetBytesUInt32( int.MaxValue );
        GetBytesUInt32( uint.MaxValue );
    }
}
