How to convert byte array to binary values and then write it in a comma separated text file

Question

I have a byte array:

newMsg.DATA = new byte[64];

How can I convert it into binary value and then write it in text file with comma separation. Comma should be in between binary values not bytes.....

like 1,1,1,0,0,0,1,1,1,1,1,0,0,0,0,0.......

Answer 1

Here is an example that uses LINQ:

byte[] arr = new byte[] { 11, 55, 255, 188, 99, 22, 31, 43, 25, 122 };

string[] result = arr.Select(x => string.Join(",", Convert.ToString(x, 2)
                     .PadLeft(8, '0').ToCharArray())).ToArray();

System.IO.File.WriteAllLines(@"D:\myFile.txt", result);

Every number in byte[] arr is converted to a binary number with Convert.ToString(x, 2) and the comma "," is added between binary values with string.Join(",",...) . At the end you can write all the elements in result to a text file by using System.IO.File.WriteAllLines .

The example above gives you this kind of output in a txt file:

0,0,0,0,1,0,1,1
0,0,1,1,0,1,1,1
1,1,1,1,1,1,1,1
...

Explanation of Convert.ToString(value, baseValue) :

The first parameter value represents the number you want to convert to a string and the second parameter baseValue represents which type of conversion you want to perform.

Posible baseValues are : 2,8,10 and 16.

BaseValue = 2 - represents a conversion to a binary number representation.

BaseValue = 8 - represents a conversion to a octal number representation.

BaseValue = 10 - represents a conversion to a decimal number representation.

BaseValue = 16 - represents a conversion to a hexadecimal number representation.

Answer 2

I think this will Help you c# provides inbuilt functionality to do so

with help of Convert.ToString(byte[],base); here base could be[2(binary),8(octal),16(HexaDecimal)]

        byte[] data = new byte[64];
        // 2nd parameter 2 is Base e.g.(binary)
        string a = Convert.ToString(data[data.Length], 2);
        StringBuilder sb = new StringBuilder();
        foreach(char ch in a.ToCharArray())
        {
            sb.Append(ch+",");
        }
        // This is to remove last extra ,
        string ans = sb.ToString().Remove(sb.Length - 1, 1);

Answer 3

This should get you going:

var bytes = new byte[] { 128, 255, 2 };
var stringBuilder = new StringBuilder();
for (var index = 0; index < bytes.Length; index++)
{
    var binary = Convert.ToString(bytes[index], 2).PadLeft(8, '0');
    var str = string.Join(",", binary.ToCharArray());
    stringBuilder.Append(str);
    if (index != bytes.Length -1) stringBuilder.Append(",");
}
Console.WriteLine(stringBuilder);
