1、string转byte数组【"<02GS0000FF>"转十六进制3C 30 32 47 53 30 30 30 30 46 46 3E】
string msg = "<02GS0000FF>";
byte[] buffer = System.Text.Encoding.ASCII.GetBytes(msg);
2、数字与byte[]之间的转换【100转byte[0x64]】
using System;
int i = 123;
byte [] intBuff = BitConverter. GetBytes(i); // 将 int 转换成字节数组
lob.Write(intBuff, 0, 4);
i = BitConverter. ToInt32(intBuff, 0); // 从字节数组转换成 int
double x = 123.456;
byte [] doubleBuff = BitConverter.GetBytes(x); // 将 double 转换成字节数组
lob.Write(doubleBuff, 0, 8);
x = BitConverter.ToDouble(doubleBuff, 0); // 从字节数组转换成 double
int i = 123;
byte [] intBuff = BitConverter. GetBytes(i); // 将 int 转换成字节数组
lob.Write(intBuff, 0, 4);
i = BitConverter. ToInt32(intBuff, 0); // 从字节数组转换成 int
double x = 123.456;
byte [] doubleBuff = BitConverter.GetBytes(x); // 将 double 转换成字节数组
lob.Write(doubleBuff, 0, 8);
x = BitConverter.ToDouble(doubleBuff, 0); // 从字节数组转换成 double
3、数字转成带占位符的string【100转"64"】
string hex = string.Format("{0:X2}", 100);//hex=64
using System;
int i = 123;
byte [] intBuff = BitConverter. GetBytes(i); // 将 int 转换成字节数组
lob.Write(intBuff, 0, 4);
i = BitConverter. ToInt32(intBuff, 0); // 从字节数组转换成 int
double x = 123.456;
byte [] doubleBuff = BitConverter.GetBytes(x); // 将 double 转换成字节数组
lob.Write(doubleBuff, 0, 8);
x = BitConverter.ToDouble(doubleBuff, 0); // 从字节数组转换成 double
int i = 123;
byte [] intBuff = BitConverter. GetBytes(i); // 将 int 转换成字节数组
lob.Write(intBuff, 0, 4);
i = BitConverter. ToInt32(intBuff, 0); // 从字节数组转换成 int
double x = 123.456;
byte [] doubleBuff = BitConverter.GetBytes(x); // 将 double 转换成字节数组
lob.Write(doubleBuff, 0, 8);
x = BitConverter.ToDouble(doubleBuff, 0); // 从字节数组转换成 double
3、数字转成带占位符的string【100转"64"】
string hex = string.Format("{0:X2}", 100);//hex=64
using System;
int i = 123;
byte [] intBuff = BitConverter. GetBytes(i); // 将 int 转换成字节数组
lob.Write(intBuff, 0, 4);
i = BitConverter. ToInt32(intBuff, 0); // 从字节数组转换成 int
double x = 123.456;
byte [] doubleBuff = BitConverter.GetBytes(x); // 将 double 转换成字节数组
lob.Write(doubleBuff, 0, 8);
x = BitConverter.ToDouble(doubleBuff, 0); // 从字节数组转换成 double
int i = 123;
byte [] intBuff = BitConverter. GetBytes(i); // 将 int 转换成字节数组
lob.Write(intBuff, 0, 4);
i = BitConverter. ToInt32(intBuff, 0); // 从字节数组转换成 int
double x = 123.456;
byte [] doubleBuff = BitConverter.GetBytes(x); // 将 double 转换成字节数组
lob.Write(doubleBuff, 0, 8);
x = BitConverter.ToDouble(doubleBuff, 0); // 从字节数组转换成 double
