How to turn a string of hexadecimal ASCII array form-CodePudding

Such as string buf="124" + "" +" 245 "+" "+" 789 ";//"" said the blank space in the middle of the
//need to convert hexadecimal ASCII form, put into a byte array, good to send out a serial port communication,

Byte [] buf16=the string converted to hexadecimal array form;

CodePudding user response:

 
Byte [] buf16=Encoding. The ASCII. GetBytes (buf);

CodePudding user response:

 buf. Split (' '). The Select (s=& gt; The Convert. ToByte (s)). ToArray ()

This is 10 hexadecimal conversion, I monitor

references on the 2nd floor buses meet response:

 buf. Split (' '). The Select (s=& gt; The Convert. ToByte (s)). ToArray ()

Output array in where

CodePudding user response:

In line of time is not short ah, give you is not complete a

 byte [] buf16=buf. Split (' '). The Select (s=& gt; The Convert. ToByte (s)). ToArray ();

CodePudding user response:

To add a 16, is the hexadecimal,
Code=csharp]
Byte [] buf16=buf. Split (' '). The Select (s=& gt; The Convert. ToByte (s, 16)). ToArray ();
[/code]

But the hex is more than 255, 124 byte can not let go, you may want to two to two, write a function,

 

Private byte [] StringToBytes16 (string source) 
{
Byte [] destination=new byte [source. Length/2]; 
For (int I=0, j=0; I & lt; Source. The Length & amp; & J & lt; Source. Length/2; I +=2, j++) 
{
String item=source. The Substring (I, 2); 
Destination [j].=the Convert ToByte (item, 16); 
} 
The return destination; 
}
