Input - String : Output - Binary Oct Dec Hex

[Markus Sommer]

Hello!

string test = char(2) + "HelloWorld" + char(29);

IsPrintableCharToDec(test);

My target:
Example
Output <2>HelloWorld<29>

public string IsPrintableCharToDec(char c)
{
string ret= c.ToString();
if ((!char.IsLetterOrDigit(c) &&
!char.IsPunctuation(c)) &&
!char.IsSymbol(c))
{
ret = "<" + c.ToString() + ">";
}
return ret;
}


Output <2>HelloWorld<1D>

public string IsPrintableCharToHex(char c)
{
string ret= c.ToString();
if ((!char.IsLetterOrDigit(c) &&
!char.IsPunctuation(c)) &&
!char.IsSymbol(c))
{
ret = "<" + c.ToString() + ">";
}
return ret;
}

Hello,

(assuming your problem is the converting to base 2, 8 or 16).

yes works well.
Is that or know you another way?

Maybe GetByteConverter? I'm not sure.

If it works stick to it.. This is a lower level infrastructure for type
conversion and I'm not even sure it supports using a base.

For simple cases see the code below.
