BitConverter::GetBytes Method (Int64)
Visual Studio 2010
Returns the specified 64-bit signed integer value as an array of bytes.
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( __int64 ) method. using namespace System; // Convert an __int64 argument to a byte array and display it. void GetBytesInt64( __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( __int64 ) " "\nmethod generates the following output.\n" ); Console::WriteLine( "{0,22}{1,30}", "__int64", "byte array" ); Console::WriteLine( "{0,22}{1,30}", "-------", "----------" ); // Convert __int64 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( Int64::MinValue ); GetBytesInt64( Int64::MaxValue ); } /* This example of the BitConverter::GetBytes( __int64 ) method generates the following output. __int64 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 */
