Description
BigInteger ToByteArray Converts a BigInteger value
to a byte array.
Syntax
BigInteger.ToByteArray has the following syntax.
public byte[] ToByteArray()
Returns
BigInteger.ToByteArray method returns
Example
The following example illustrates how some BigInteger values are represented in byte arrays.
/*from ww w .j a v a 2s . c o m*/
using System;
using System.Numerics;
public class Example
{
static byte[] bytes;
public static void Main()
{
BigInteger[] numbers = { Int64.MinValue, Int64.MaxValue,
BigInteger.Parse("90123123981293054321") };
foreach (BigInteger number in numbers)
{
bytes = number.ToByteArray();
Console.Write("{0} ({1}) -> ", number, number.ToString(GetSpecifier()));
Console.Write("{0} bytes: ", bytes.Length);
foreach (byte byteValue in bytes)
Console.Write("{0:X2} ", byteValue);
Console.WriteLine();
}
}
private static string GetSpecifier()
{
return "X" + (bytes.Length * 2).ToString();
}
}
The code above generates the following result.
