Hexadecimal

In the code below, ans is declare as byte.  It reads values from the registry and converts them to a string.  However in the string the values are not returned as hexadecimal as they are in the registry instead they are converted to decimal (i.e. "23" instead of "17" and "245" instead of "f5").  Can anyone help me keep these in hexadecimal format   I appreciate the help.  Thanks


ans = regKey.GetValue("F")
For i = 0 To ans.Length - 1
' Create a string from the byte array
value = value + Convert.ToString(ans.GetValue(i)) + " "
Next

ListBox1.Items.Add(value)

    Do you mean convert it to binary Or do you mean ascii or UTF-8 character representing a hex string

    Hello

    I have a similar sort of problem, accept I wish to convert a string to hexadecimal, and then write it to a registry key.

    I would like to use the string that is typed into : txtPassword

    I can manage all the reading and writing registry stuff, I just cant figure out how to convert a string to hexadecimal!

    Any ideas on this would be great.

    Would something like this work



    Dim bytes As Byte() = New Byte() {1, 23, 245, 17}
    Dim sb As New System.Text.StringBuilder
    For Each b As Byte In bytes
       sb.Append(b.ToString(
    "x2"))
       sb.Append(" ")
    Next
    ListBox1.Items.Add(sb.ToString())

     


    The only other change that I made was to use a string builder instead of a string, since that is a much faster method of building a string like this. Using your original method of concatenating strings will produce the same output...
