You could implement your own based on .NET 4.0’s BigInteger class. I did this for fun, it does multiplication only: public struct BigDecimal { public BigInteger Integer { get; set; } public BigInteger Scale { get; set; } public BigDecimal(BigInteger integer, BigInteger scale) : this() { Integer = integer; Scale = scale; while (Scale > … Read more
As of .NET 4.0 you can use the System.Numerics.BigInteger class. See documentation here: http://msdn.microsoft.com/en-us/library/system.numerics.biginteger(v=vs.110).aspx Another alternative is the IntX class. IntX is an arbitrary precision integers library written in pure C# 2.0 with fast – O(N * log N) – multiplication/division algorithms implementation. It provides all the basic operations on integers like addition, multiplication, comparing, … Read more
You can use Enumerable.SequenceEqual method. using System; using System.Linq; … var a1 = new int[] { 1, 2, 3}; var a2 = new int[] { 1, 2, 3}; var a3 = new int[] { 1, 2, 4}; var x = a1.SequenceEqual(a2); // true var y = a1.SequenceEqual(a3); // false If you can’t use .NET 3.5 … Read more
