C# dynamic operator

I don’t know if this is possible but let me ask:

For example I generate a simple math operation from a list

such as

List lstMat={=,+,-}

Then I generate a random value between 0-2 and select that operator from that list

such as

    int ir1=1;
    int ir2=2;

    int irNew=    ir1 lstMat[1] ir2 ;
    //irNew would be 3

Is this possible?

Answer 1

The closest thing I can think of

List<Func<int, int, int>> lstMat = new List<Func<int, int, int>>()
{
    (x,y)=>x.CompareTo(y),
    (x,y)=>x+y,
    (x,y)=>x-y
};

int ir1=1;
int ir2=2;

int irNew= lstMat[1](ir1,ir2);
