Body
I have an array of bytes (any length), and I want to encode this array into string using my own base encoder. In <code>.NET</code> is standard <code>Base64</code> encoder, but what if I want to encode the array in <code>Base62</code>, <code>Base53</code> or <code>Base13</code>? Is it even possible to create such universal base encoder? I know I could do it the simple way, that is, for each byte reserve fixed number of chars (in case of <code>Base62</code>, that would be 5 chars), and do direct byte->chars encoding, but I would be wasting space, as 5 <code>Base62</code> chars are able to contain more than 1 byte, but less than 2 bytes. How should I write such an encoder? Or is there already some class for this? And please note that I need universal decoder as well, otherwise this is useless to me. <h2>Resources</h2> As the solution is already known (use <code>BigInteger</code>), I would just like to put here some resources relating the <code>BigInteger</code> class, as it is not available in .NET 3.5: <a href="https://stackoverflow.com/questions/176775/big-integers-in-c">Big integers in C#</a> <a href="http://intx.codeplex.com/" rel="nofollow noreferrer">http://intx.codeplex.com/</a> <a href="https://svn.apache.org/repos/asf/incubator/heraldry/libraries/csharp/openid/trunk/Mono/Mono.Math/BigInteger.cs" rel="nofollow noreferrer">https://svn.apache.org/repos/asf/incubator/heraldry/libraries/csharp/openid/trunk/Mono/Mono.Math/BigInteger.cs</a> <a href="http://www.codeproject.com/KB/cs/BigInteger_Library.aspx" rel="nofollow noreferrer">http://www.codeproject.com/KB/cs/BigInteger_Library.aspx</a> <a href="http://www.codeproject.com/KB/cs/biginteger.aspx" rel="nofollow noreferrer">http://www.codeproject.com/KB/cs/biginteger.aspx</a>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
