BitConverter.GetBytes Method (Int32)
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Returns the specified 32-bit signed integer value as an array of bytes.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- value
- Type: System.Int32
The number to convert.
The following code example converts the bit patterns of Int32 values to Byte arrays with the GetBytes method.
// Example of the BitConverter.GetBytes( int ) method. using System; class Example { const string formatter = "{0,16}{1,20}"; // Convert an int argument to a byte array and display it. public static void GetBytesInt32(System.Windows.Controls.TextBlock outputBlock, int argument) { byte[] byteArray = BitConverter.GetBytes(argument); outputBlock.Text += String.Format(formatter, argument, BitConverter.ToString(byteArray)) + "\n"; } public static void Demo(System.Windows.Controls.TextBlock outputBlock) { outputBlock.Text += String.Format( "This example of the BitConverter.GetBytes( int ) " + "\nmethod generates the following output.\n") + "\n"; outputBlock.Text += String.Format(formatter, "int", "byte array") + "\n"; outputBlock.Text += String.Format(formatter, "---", "----------") + "\n"; // Convert int values and display the results. GetBytesInt32(outputBlock, 0); GetBytesInt32(outputBlock, 15); GetBytesInt32(outputBlock, -15); GetBytesInt32(outputBlock, 0x100000); GetBytesInt32(outputBlock, -0x100000); GetBytesInt32(outputBlock, 1000000000); GetBytesInt32(outputBlock, -1000000000); GetBytesInt32(outputBlock, int.MinValue); GetBytesInt32(outputBlock, int.MaxValue); } } /* This example of the BitConverter.GetBytes( int ) method generates the following output. int byte array --- ---------- 0 00-00-00-00 15 0F-00-00-00 -15 F1-FF-FF-FF 1048576 00-00-10-00 -1048576 00-00-F0-FF 1000000000 00-CA-9A-3B -1000000000 00-36-65-C4 -2147483648 00-00-00-80 2147483647 FF-FF-FF-7F */
