CharVal() [1/2]

static byte pluginbase.Helpers.Hex.CharVal ( char  c )

static

Convert a hex digit to its corresponding decimal digit

Returns

The base10 digit.

Parameters

c

C.

Attribute: c & 0xff

;

        {

CharVal() [2/2]

static byte pluginbase.Helpers.Hex.CharVal ( char  c1, char  c2  )

static

Gets the byte val of 2 hex digits

Returns

The decimal value.

Parameters

c1	C1.
c2	C2.

Attribute: c1 & 0xff] << 4 | _charValues[c2 & 0xff

);

        {
            return (byte)(_charValues[c1 & 0xff] << 4 | _charValues[c2 & 0xff]);

static

Convert an integer to its hex string

Returns

The hex.

Parameters

val	Value.
minLen	Minimum length.

Attribute: val & 0xf

);

        {
            var s = new StringBuilder();
            while(val > 0)
            {
                s.Insert(0, _valueSymbol[val & 0xf]);
                val >>= 4;
            }
            while (s.Length < minLen)
                s.Insert(0, '0');
            return s.ToString();
        }

ToHex() [2/2]

static string pluginbase.Helpers.Hex.ToHex ( byte []  bytes )

static

Convert an array of bytes to its hex string

Returns

The hex.

Parameters

bytes

Bytes.

); //Right bits

        {
            var s = new StringBuilder();
            for (int i=0; i<bytes.Length; ++i)
            {
                s.Append(_valueSymbol[bytes[i] >> 4]); //Left bits
                s.Append(_valueSymbol[bytes[i] & 0xf]); //Right bits
            }
            return s.ToString();
        }

ToInt32()

static int pluginbase.Helpers.Hex.ToInt32 ( string  s )

static

;

        {
            int v = 0;
            for (int i=0; i<s.Length; ++i)
            {
                v = (v << 4) | _charValues[s[i] & 0xff];
            }
            return v;
        }
