Is there a string math evaluator in .NET?

Question

If I have a string with a valid math expression such as:

String s = \"1 + 2 * 7\";

Is there a built in library/function in .NET that will p

MathNet.Symbolics

using System;
using static MathNet.Symbolics.SymbolicExpression;
using static System.Console;
using static System.Numerics.Complex;
using Complex = System.Numerics.Complex;

namespace MathEvaluator
{
    class Program
    {
        static readonly Complex i = ImaginaryOne;

        static void Main(string[] args)
        {
            var z = Variable("z");
            Func f = Parse("z * z").CompileComplex(nameof(z));
            Complex c = 1 / 2 - i / 3;
            WriteLine(f(c));


            var x = Variable("x");
            Func g = Parse("x * x + 5 * x + 6").Compile(nameof(x));
            double a = 1 / 3.0;
            WriteLine(g(a));
        }
    }
