Question

I have been trying to use the BigInteger type, that is supposedly new in .NET Framework 4.0.

I don’t seem to be able to get to it, and get an error when trying to reference it via Using System.Numerics.

Any idea what I’m doing wrong? Sorry if this is a stupid question…

Answer 1

1. Add a reference to the System.Numerics assembly to your project.

   a. In Solution Explorer, right-click the project node and click Add Reference.

   b. In the Add Reference dialog box, select the .NET tab.

   c. Select System.Numerics, and then click OK.

2. Add a using directive importing the System.Numerics namespace:

   using System.Numerics;
   

3. Use the BigInteger structure:

   var i = new BigInteger(934157136952);
