You are developing a Windows Forms (WinForms) application. The application displays a TreeView that has 1,000 nodes.
You need to ensure that if a user expands a node, and then collapses the TreeView, the node object is kept in memory unless the Garbage Collector requires additional memory.
Which object should you use to store the node?

You have the following code.
You need to ensure that the classify string contains the next "positive" if the input number is more than zero and "negative" if the input number is less than or equal to zero.
How should you complete the code? To answer, drag the appropriate code elements to the correct targets in the answer area. Each code element may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

You are developing a class named Temperature.
You need to ensure that collections of Temperature objects are sortable.
You have the following code:
Which code segments should you include in Target 1, Target 2 and Target 3 to complete the code? (To answer, drag the appropriate code segments to the correct targets in the answer area. Each code segment may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.)

Explanation:
Note:
Target 1:
The role of IComparable is to provide a method of comparing two objects of a particular type. This is necessary if you want to provide any ordering capability for your object.
Incorrect: The role of IComparer is to provide additional comparison mechanisms. For example, you may want to provide ordering of your class on several fields or properties, ascending and descending order on the same field, or both.
Target 2, Target 3:
Example:
// Implement IComparable CompareTo method - provide default sort order.
int IComparable.CompareTo(object obj)
{
car c=(car)obj;
return String.Compare(this.make,c.make);
}
