Need help with C# programming
Given Code:

**************Form1.Designer.cs
If you run it, you will notice that every time you exit the program, all your data in your dictionary is lost. Please fix that. Add 2 buttons to the form, one is "Save Data" the other is "Load Data" Save data reads each animal object from the Dictionary and saves the 4 values in a SQL table. Load data reads that SQL table and creates new objects for each row and adds them to the dictionary. So, if the user starts the program, add 3 animals using the form, and then clicks the new Save button, and then stops the program and re-starts it, and clicks the load button, those 3 animals should be back in the dictionary. If they then add 2 more animals, those 2 should be ADDED to the existing data in SQL. So you can either - in the save, clear all SQL rows and then just add all the entries from the DB (easier, but not very efficient!) Or, - you could add a 5th property to the objects called "saved", and then as you write dictionary objects out to SQL, check that property, if it is false, set it to true and write it to SQL, if it is already true, skip it.
