Question

Is there any way to convert from DB.Null to decimal in C#?

Like

Object[] returnvalue = new Object[1];
returnvalue[0] = null;
returnvalue[0] = Convert.ToDecimal(returnvalue[returnvalue.Length - 1]);

Though CLR is saying that DBNull.Value cannot be type casted. Still I want to know is there

any work around?
Thanks in advance

How do you expect to cast null to anything? It’s null, nothing, nada…

That said, your best bet would be to check for DBNull (or null in the above case) and use/return/whatever default(decimal) instead, though null and DBNull both have a significant semantic difference from just a default value; they are the absence of a value, so this is probably not what you want to do.
