Condense single-line methods

                   public override object SolvePart1() 
        
                   { 
        
                       return passwordAndPolicies.Count(p => p.min <= p.password.CountChar(p.@char) 
        
                                                        && p.password.CountChar(p.@char) <= p.max); 
        
                   } 
        
                   public override object SolvePart2() 
        
                   { 
        
                       return passwordAndPolicies.Count(p => p.password[p.min - 1] == p.@char 
        
                                                           ^ p.password[p.max - 1] == p.@char); 
        
                   }

For single-line methods, you can use expression bodies.

Regular expressions

Try to use regular expressions when parsing text. It will make your life much easier.

           string[] parts = line.Split(' '); 
        
           (int min, int max, char @char, string password) passwordAndPolicy; 
        
           passwordAndPolicy.min = int.Parse(parts[0].Split('-')[0]); 
        
           passwordAndPolicy.max = int.Parse(parts[0].Split('-')[1]); 
        
           passwordAndPolicy.@char = char.Parse(parts[1].Substring(0,1)); 
        
           passwordAndPolicy.password = parts[2];
