casting an object to a specific type

[Steve Teeples]

I have a method that passes in two string objects (both numerical numbers)
and a string identifying their type.

public bool DoCompare(strin g num1, string num2, string theirType)
{
System.Type type = System.Type.Get Type(theirType) ;
return ((type)num1 <= (type)num2) ? true : false;
}

The compiler doesn't like the (type) casting that I do. What is the proper
way of casting an object to its correct type to do such a mathematical
operation?

This question was answered in another thread. Thanks.

I was looking at some of your other threads and I saw a REALLY big if,
but here is a simpler version and number safe...

public bool DoCompare( string num1, string num2) {
Decimal num1 = Decimal.Parse( num1);
Decimal num2 = Decimal.Parse( num2);

return Decimal.op_Less ThanOrEqual( num1, num2);
}

Re: casting an object to a specific type

I see you're simply converting everything to a double and managing it that
way. Simple and dependable. Thanks for the insight.
