How to store Object in SortedList

I have a sorted list that contains a name and a integer value. I am new to c sharp, so I am not sure what am I doing wrong.

My code:

//first class

class Tool {
 public Tool(string name, int quantity)
        {
            this.name = name;
            this.quantity = quantity;
        }
}

//main class

This is a different class (2nd class) 

 SortedList<Tool> gardeningTools = new SortedList<Tool>(); //error


        gardeningTools.Add(new Tool("nameA", 1)); //error

Here I am trying to add some kinds of tools inside the gardening tools. The above two lines has error says "new" is not a valid keyword and both of the lines are red. I assume it's completely a wrong way to write like that. Could anyone tell me how to write it the right way?

SortedList requires two generic type arguments, the type of the key and the type of the item you're storing. In your case this might be:

SortedList<string, Tool> gardeningTools = new SortedList<string, Tool>();

Assuming that Tool is defined something like this:

class Tool
{
  public Tool(string name, int quantity)
  {
    this.Name = name;
    this.Quantity = quantity;
  }

  public string Name{get;}
  public int Quantity{get;}
}

Also, the Add method takes two parameters, the key, and the value, so you want something like this:

Tool tool = new Tool("nameA", 1);
gardeningTools.Add(tool.Name, tool);

Now you can acccess them in order. For example:

foreach(var tool in gardeningTools.Values)
{
  Console.WriteLine("Name = {0}, Qty = {1}", tool.Name, tool.Quantity);
}
