How do I handle errors in C# collections?

In C#, you can handle errors in collections using try-catch blocks. For example, when accessing an index in a list, you can catch an IndexOutOfRangeException.

Can you show me a code example?

Sure! Here's a simple example:

List<int> numbers = new List<int> { 1, 2, 3 };
try {
    int value = numbers[5]; // This will throw an exception
} catch (IndexOutOfRangeException e) {
    Console.WriteLine("Error: " + e.Message);
}

What about handling null values in collections?

You can check for null values before performing operations. For instance:

List<string> names = null;
if (names != null) {
    // Safe to access names
} else {
    Console.WriteLine("The collection is null.");
}
