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
Assembly:  mscorlib (in mscorlib.dll)

public static byte[] GetBytes(
	uint value


Type: System.UInt32
The number to convert.

Return Value

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

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

   // Convert a uint argument to a byte array and display it.
   public static void GetBytesUInt32(System.Windows.Controls.TextBlock outputBlock, uint argument)
      byte[] byteArray = BitConverter.GetBytes(argument);
      outputBlock.Text += String.Format(formatter, argument,
          BitConverter.ToString(byteArray)) + "\n";

   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
      outputBlock.Text += String.Format(
          "This example of the BitConverter.GetBytes( uint ) " +
          "\nmethod generates the following output.\n") + "\n";
      outputBlock.Text += String.Format(formatter, "uint", "byte array") + "\n";
      outputBlock.Text += String.Format(formatter, "----", "----------") + "\n";

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

This example of the BitConverter.GetBytes( uint )
method generates the following output.

            uint          byte array
