Create a key value pair in c#

I have been trying to create a class which has a property for key value pair, I have tried the Dictionary keyword, but I need something like this:

ClassName clsName = new ClassName();

clsName.PropertyName.Add["Key"] = value;

I want it to be dynamic property so I can send any datatype.

If we suppose that KeyValuePair has as a key as a string, and a value as int, then you could try this:

clsName.PropertyName = new KeyValuePair<string, int>("keyName", 2);

You don't need to use the Add method. Actually, the latter makes sense when you have a collection and don't want to add an item to it. From what you have posted in your question, we can't say that this is your case.

I'm not sure if I understood the question correctly, but apparently your requirements can be met using a generic Dictionary, where the key type parameter is string and the value type parameter is object, i.e. you could use Dictionary<string,object> like this:

public class ClassName {
    public Dictionary<string, object> Dictionary { get; set; }
}

And then:

ClassName classObject = new ClassName();
classObject.Dictionary.Add("Key", new { "value" });

public class ClassName
{
  public KeyValuePair<string, object> PropertyName {get; set; }
}

var c = new ClassName();
c.PropertyName = new KeyValuePair<string, object>("keyName", someValue);

or, if you need to store multiple values, use Dictionary<string, object> as type of your property.

public class ClassName
{
    public ClassName()
    {
       this.PropertyName = new Dictionary<string, object>();
    }

    public Dictionary<string, object> PropertyName {get; set; }
}

var c = new ClassName();
c.PropertyName.Add("stringKey", anyValue);

I suggest you to simply use the "HASHTABLE" its so much easier for you.Below is syntax.

    Hashtable hashtable = new Hashtable();
    hashtable.Add("Area", 1000);
    hashtable.Add("Perimeter", 55);

1st parameter represents the key and 2nd one represents the value.So its the key value pair.

If you are after a basic class, for key and value, would

KeyValuePair<string, object>

work for you?
