I have this:

 this.button1.Text = DateTime.Now.Ticks.ToString();


which gives me numbers like:


632855413326400752


what I want to do is store this number, not in a text box, but in a variable whose type is large enough to store this value.


I don't know of any variable large enough to store this number.


What options do I have?

Also, i need an online reference for the C# data types and how large of values can each one hold:  int, long, double, word, etc.

Huh, I guess a "long" does hold a number that big.

Here is the link you want, just click on the data type you would to see more info about it:  http://msdn2.microsoft.com/en-us/ya5y69ds.aspx

You can use long to store that number, or use ulong to be safe because that number can't be negative anyways.

Cheers,

Aaron

Hi, just to make it clear:

long actualNow = DateTime.Now.Ticks;

because DateTime.Now.Ticks property is defined:

public long Ticks {get; }

regards,
Kate

You could also use the BigInteger datatype from J#:

(from http://msdn.microsoft.com/msdnmag/issues/05/12/NETMatters/)

BigInteger i = new BigInteger(ulong.MaxValue.ToString());
BigInteger iSquared = i.multiply(i);
Console.WriteLine("i:\t" + i);
Console.WriteLine("i^2:\t" + iSquared);



i:      18446744073709551615
i^2:    340282366920938463426481119284349108225
