Runtime conversion of a generic Object to its underlying type

Ever have to do manual serialization of data in a DataSet?  The challenge is being able to call BitConverter.GetBytes on the data element when at compile time you have no idea what it’s type is, and GetBytes doesn’t accept an Object (though I’d argue maybe it should and attempt to convert the underlying type if it’s resolvable).

Here’s my solution:

byte[] elementBytes = (byte[])typeof(BitConverter).GetMethod(
“GetBytes”, new Type[] { dataRow[columnNumber].GetType() }).Invoke(
    null, new object[] { dataRow[columnNumber] });
