BitConverter::GetBytes Method (UInt64)
Visual Studio 2010
Returns the specified 64-bit unsigned integer value as an array of bytes.
Assembly: mscorlib (in mscorlib.dll)
[CLSCompliantAttribute(false)] public: static array<unsigned char>^ GetBytes( unsigned long long value )
Parameters
- value
- Type: System::UInt64
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 UInt64 values to Byte arrays with the GetBytes method.
// Example of the BitConverter::GetBytes( unsigned __int64 ) method. using namespace System; // Convert an unsigned __int64 argument to a byte array and display it. void GetBytesUInt64( unsigned __int64 argument ) { array<Byte>^byteArray = BitConverter::GetBytes( argument ); Console::WriteLine( "{0,22}{1,30}", argument, BitConverter::ToString( byteArray ) ); } int main() { Console::WriteLine( "This example of the BitConverter::GetBytes( unsigned " "__int64 ) \nmethod generates the following output.\n" ); Console::WriteLine( "{0,22}{1,30}", "unsigned __int64", "byte array" ); Console::WriteLine( "{0,22}{1,30}", "----------------", "----------" ); // Convert unsigned __int64 values and display the results. GetBytesUInt64( 0xFFFFFF ); GetBytesUInt64( 1000000000 ); GetBytesUInt64( 0x100000000 ); GetBytesUInt64( 0xAAAAAAAAAAAA ); GetBytesUInt64( 1000000000000000000 ); GetBytesUInt64( 10000000000000000000 ); GetBytesUInt64( UInt64::MinValue ); GetBytesUInt64( Int64::MaxValue ); GetBytesUInt64( UInt64::MaxValue ); } /* This example of the BitConverter::GetBytes( unsigned __int64 ) method generates the following output. unsigned __int64 byte array ---------------- ---------- 16777215 FF-FF-FF-00-00-00-00-00 1000000000 00-CA-9A-3B-00-00-00-00 4294967296 00-00-00-00-01-00-00-00 187649984473770 AA-AA-AA-AA-AA-AA-00-00 1000000000000000000 00-00-64-A7-B3-B6-E0-0D 10000000000000000000 00-00-E8-89-04-23-C7-8A 0 00-00-00-00-00-00-00-00 9223372036854775807 FF-FF-FF-FF-FF-FF-FF-7F 18446744073709551615 FF-FF-FF-FF-FF-FF-FF-FF */
