C# BYTE[] 與16進制字符串互相轉換

byte[] 轉16進制字符串

方法一、

BitConverter.ToString(resultArray).Replace("-", "")

 

方法二、

/// <summary> 
/// 字節數組轉16進制字符串 
/// </summary> 
/// <param name="bytes"></param> 
/// <returns></returns> 
public static string byteToHexStr(byte[] bytes)
{
string returnStr = "";
if (bytes != null)
{
for (int i = 0; i < bytes.Length; i++)
{
returnStr += bytes[i].ToString("X2");
}
}
return returnStr;
}

 

16進制的字符串轉為byte[]

/// <summary>
/// 將16進制的字符串轉為byte[]
/// </summary>
/// <param name="hexString"></param>
/// <returns></returns>
public static byte[] StrToHexByte(string hexString)
{
hexString = hexString.Replace(" ", "");
if ((hexString.Length % 2) != 0)
hexString += " ";
byte[] returnBytes = new byte[hexString.Length / 2];
for (int i = 0; i < returnBytes.Length; i++)
returnBytes[i] = Convert.ToByte(hexString.Substring(i * 2, 2), 16);
return returnBytes;
}
