c How do I convert a byte array to a string so that it can be displayed in the textbox?

You didn't show the array when you wrote it like that!

You should: byte a = new byte[10] ;

foreach(byte b in a)

I didn't test it! But that's the right way to write it!

I hope to give a good review, and I'll collect the score again.

There are two ways to do this:1.

byte a = new byte[10] ;

foreach (var b in a)

2。Rewrite byte's tostring method, but I think the first one is enough for you to use and test, no problem.

1. All of them must first know what encoding your byte array is based on, and then you can convert back to string according to this encoding

Example: byte bytes ="A string to be converted to a byte array");If you want to convert back to the correct string, it must also be UTF-8 encoded, otherwise the successful conversion will be garbled.

string s = ;Here the byte array is converted back to a string.

If it's just for display, there's no need to convert it to an array, just like this:

To convert to an array, you can use the split function, string nums= char);

Whether it's a string array or an int array, your above declaration can't be compiled.

I didn't look at Bai Cai's Du words, the knot you wanted.

zhi guo dao is this.

byte b = new byte ;

The output is back to answer 22-fe-77-ef

string to byte array.

byte arr = "abcde")

byte array to string with :

string str = ;

You can go directly to it, and directly call getbytes(); Isn't it possible?

You're mistaken, there are no two 0s in the byte, 05 is a hexadecimal string, you just need to pass the string into the following function and send the resulting array.

public static byte hexstringtobytearray(string s)

return buffer;}

string[0] = byte[0].tostring().padleft(2, '0');Less than 2 bits on the left are supplemented with the string 0, which is displayed as: 00

string[1] = byte[1].tostring().padleft(2, '0');

string[2] = byte[2].tostring().padleft(2, '0');

..And so on.

string5] = byte[5].tostring().padleft(2, '0');--- is displayed as: 05

I don't understand why I have to convert it to a byte array, and the string array can't be.

3 all byte b = .

string s = ;

Remove white space (spaces).

s = ;
