Sample Program to Convert String to Hex and Hex to String in CSharp (C#)

Here is the sample program to convert String to Hex and Hex to String in CSharp (C#).

String to Hex:

public static string ConvertStringToHex(String input, System.Text.Encoding encoding)
{
    Byte[] stringBytes = encoding.GetBytes(input);
    StringBuilder sbBytes = new StringBuilder(stringBytes.Length * 2);
 
    foreach (byte b in stringBytes)
    {
        sbBytes.AppendFormat("{0:X2}", b);
    }
 
return sbBytes.ToString();
}

Hex to String:

public static string ConvertHexToString(String hexInput, System.Text.Encoding encoding)
{
    int numberChars = hexInput.Length;
    byte[] bytes = new byte[numberChars / 2];
 
    for (int i = 0; i < numberChars; i += 2)
    {
        bytes[i / 2] = Convert.ToByte(hexInput.Substring(i, 2), 16);
    }
 
    return encoding.GetString(bytes);
}
