BitConverter.GetBytes Method (Int64)
.NET Framework 4.5
Returns the specified 64-bit signed integer value as an array of bytes.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Parameters
- value
- Type: System.Int64
The number to convert.
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 Int64 values to Byte arrays with the GetBytes method.
// Example of the BitConverter.GetBytes( long ) method. using System; class GetBytesInt64Demo { const string formatter = "{0,22}{1,30}"; // Convert a long argument to a byte array and display it. public static void GetBytesInt64( long 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( long ) " + "\nmethod generates the following output.\n" ); Console.WriteLine( formatter, "long", "byte array" ); Console.WriteLine( formatter, "----", "----------" ); // Convert long values and display the results. GetBytesInt64( 0 ); GetBytesInt64( 0xFFFFFF ); GetBytesInt64( -0xFFFFFF ); GetBytesInt64( 1000000000 ); GetBytesInt64( -1000000000 ); GetBytesInt64( 0x100000000 ); GetBytesInt64( -0x100000000 ); GetBytesInt64( 0xAAAAAAAAAAAA ); GetBytesInt64( -0xAAAAAAAAAAAA ); GetBytesInt64( 1000000000000000000 ); GetBytesInt64( -1000000000000000000 ); GetBytesInt64( long.MinValue ); GetBytesInt64( long.MaxValue ); } } /* This example of the BitConverter.GetBytes( long ) method generates the following output. long byte array ---- ---------- 0 00-00-00-00-00-00-00-00 16777215 FF-FF-FF-00-00-00-00-00 -16777215 01-00-00-FF-FF-FF-FF-FF 1000000000 00-CA-9A-3B-00-00-00-00 -1000000000 00-36-65-C4-FF-FF-FF-FF 4294967296 00-00-00-00-01-00-00-00 -4294967296 00-00-00-00-FF-FF-FF-FF 187649984473770 AA-AA-AA-AA-AA-AA-00-00 -187649984473770 56-55-55-55-55-55-FF-FF 1000000000000000000 00-00-64-A7-B3-B6-E0-0D -1000000000000000000 00-00-9C-58-4C-49-1F-F2 -9223372036854775808 00-00-00-00-00-00-00-80 9223372036854775807 FF-FF-FF-FF-FF-FF-FF-7F */
