一、int、float、double轉byte[]
均使用System.BitConverter.GetBytes()。
1 int iii = 1; 2 float fff = 1234.12346f; 3 double ddd = 12.1264567; 4 5 byte[] b1,b2 = new byte[4]; 6 byte[] b3 = new byte[8]; 7 b1 = BitConverter.GetBytes(iii); 8 b2 = BitConverter.GetBytes(fff); 9 b3 = BitConverter.GetBytes(ddd);
二、string轉byte[]
1 string str1 = "11111111"; 2 byte[] b4 = Encoding.Default.GetBytes(str1);
三、byte[]轉int、float、double、string
還是用BitConverter
1 byte[] b5 = new byte[4] { 0x01, 0x02, 0x03, 0x04 }; 2 byte[] b6 = new byte[8] { 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08 }; 3 int i2 = BitConverter.ToInt32(b5, 0); 4 float f2 = BitConverter.ToSingle(b5, 0); 5 double d2 = BitConverter.ToDouble(b6, 0); 6 string str2 = BitConverter.ToString(b6, 0);
四、兩個byte[]之間截取、復制
用System.Array可以完成對數組的創建、搜索、復制等操作
1 byte[] b7 = new byte[] { 0x01, 0x02, 0x03, 0x04, 0x05, 0x06 }; 2 byte[] b8 = new byte[2]; 3 Array.Copy(b7, 2, b8, 0,2);
