Convert Expression> to String and vice versa In c#

I want to convert Expression<Func<Loan, bool>> To string and vice versa. can I do it? how can implement ConvertStringToExpression method?

internal class Program
{
    public class Loan
    {
        public bool IsActive { get; set; }
    }

    private static void Main(string[] args)
    {
        Expression<Func<Loan, bool>> expression = l => !l.IsActive;

        var expStr = ConvertExpressionToString(expression);

        var exp = ConvertStringToExpression(expStr);
    }

    public static string ConvertExpressionToString(Expression<Func<Loan, bool>> expression)
    {
        //return ???
        throw new NotImplementedException();
    }

    public static string ConvertStringToExpression(string expression)
    {
        //return ???
        throw new NotImplementedException();
    }
}
