Question

I have a classA that has some public properties & overrides TosString method to to concatenate strings in these properties. It also has a property that returns int key;

I am using

string str = value1 + value2 + value3; 

each value has # separated properties of classA

string[] values = Regex.Split(str,'#');

foreach(classA value in values)
{
    dictionary.add(value.key, value);
}

This works fine

=====================================================================

For this scenario I want to use

values.ToDictionary

Can any one suggest how to use this?

It occurs to me that you might really want is to get the properties from a class and turn them into key-value pairs in a dictionary.

If that’s what you’re looking to do then Class -> String -> Array -> Dictionary is taking the long way.

If that’s the case maybe you want to try a more direct approach

Given a class like this

 class classA
    { 
        public string Name{get;set;}
        public string  website { get; set; }
        public string location { get; set; }
        public int age { get; set; }
        public int reputation { get; set; }

        private string somthingPrivate { get; set; }


    }

The following creates a dictionary variable named result.

classA test = new classA() { Name = "Jeff Atwood", website = "codinghorror.com/blog", location = "El Cerrito, CA", age = 40, reputation = 15653 };


var result = test.GetType().GetProperties().ToDictionary(property => property.Name,
                                                    property => property.GetValue(test,null),
                                                     StringComparer.OrdinalIgnoreCase);

foreach (var key in result.Keys)
    Console.WriteLine("{0} : {1}", key, result[key]);

And outputs this

Name : Jeff Atwood
website : codinghorror.com/blog
location : El Cerrito, CA
age : 40
reputation : 15653
