BitConverter.GetBytes Method (Single)
Returns the specified single-precision floating point value as an array of bytes.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Parameters
- value
- Type: System.Single
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 Single values to Byte arrays with the GetBytes method.
// Example of the BitConverter.GetBytes( float ) method. using System; class GetBytesSingleDemo { const string formatter = "{0,16:E7}{1,20}"; // Convert a float argument to a byte array and display it. public static void GetBytesSingle( float 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( float ) " + "\nmethod generates the following output.\n" ); Console.WriteLine( formatter, "float", "byte array" ); Console.WriteLine( formatter, "-----", "----------" ); // Convert float values and display the results.
