is there any method provide in .net for conversion like byteToHex(byte[])

Byte[] Bytes = {0xFF, 0xD0, 0xFF, 0xD1} to "FFD0FFD1"

thnx

None that I've found. I use:

StringBuilder sb = new StringBuilder(ba.Length * 2);
foreach (byte b in
ba)
{
sb.AppendFormat(
"{0:x2}"
, b)
}
return
sb.ToString();

Note however, if

Byte[] Bytes = {0xFF, 0xD0, 0xFF, 0xD1} to "FF-D0-FF-D1"

is acceptable, you can use:

BitConverter.ToString(Bytes);

thnx a lot, this work for me

string hex = BitConverter.ToString(Bytes);
hex = hex.Replace("-","");

although not "one-step" solution, but great enough

Faster variant:

Re: Visual C# General byte[] Array to Hex String

PZahra

Here's my function:

public static string HexStr(byte[] p) {

char[] c=new char[p.Length*2 + 2];

byte b;

c[0]='0'; c[1]='x';

for(int y=0, x=2; y<p.Length; ++y, ++x) {

b=((byte)(p[y ]>>4));

c[x]=(char)(b>9 b+0x37 : b+0x30);

b=((byte)(p[y ]&0xF));

c[++x]=(char)(b>9 b+0x37 : b+0x30);

}

return new string(c);

}

it puts "0x" at the beginning of the string, but that's a simple matter to change.

HexStr(new byte[]{0x00,0xDE,0xAD,0xBE,0xEF,0x99}) ==> "0x00DEADBEEF99"

Sorry to cut you off up there, but when dealing with big arrays, every character - every processor cycle - counts.
