Can two objects reference each other?
Of course you can have objects reference each other. You could simply pass the this pointer in both objects to each other, which is perfectly valid.
How to check If two objects are Equal c#?
The most common way to compare objects in C# is to use the == operator. For predefined value types, the equality operator (==) returns true if the values of its operands are equal, false otherwise. For reference types other than string, == returns true if its two operands refer to the same object.
Can two objects have same reference in Java?
Yes, two or more references, say from parameters and/or local variables and/or instance variables and/or static variables can all reference the same object.
Can the same object belong to two different ArrayLists?
An ArrayList can contain multiple references to the same object. The same object may belong to 2 different ArrayLists. ArrayList’s add method makes a copy of the object and adds it to the list. Two variables can refer to the same Arraylist.
Can you force two objects to refer to each other in a way that they never garbage collected?
3 Answers. No. The garbage collector doesn’t count references to know is an object is collectable or not.
Should I override equals C#?
If you’re implementing a reference type, you should consider overriding the Equals method if your type looks like a base type, such as Point, String, BigNumber, and so on. Override the GetHashCode method to allow a type to work correctly in a hash table.
What is difference between == and equals in C#?
The Equality Operator ( ==) is the comparison operator and the Equals() method compares the contents of a string. The == Operator compares the reference identity while the Equals() method compares only contents. In the first example we assigned a string variable to another variable.
How do you make one object refer to the same object?
11. How to make more than one object refer to the same object? Explanation: The object must get initialized with another object at time of declaration only. We don’t have to create a new object we just have to get name of new object because there after same address will be referred.
Can a list contain multiple references to the same object?

Should I use GC collect?
Collect() to bring the heap to a mostly-known state. For example, when benchmarking, you need to make sure that you start each run from a known state, and GC. Collect() helps with this. It should not be used to dispose of unmanaged resources — for that you should use using or manually call Dispose .
