Array & ArrayList class<\/strong><\/h4>\n

In C#, an array is a fixed-size collection of elements of the same data type, whereas an ArrayList is a dynamic collection that can grow or shrink in size as needed.<\/p>\n

To create an array in C#, you can use the following syntax:<\/p>\n

csharp<\/p>\n

Copy code<\/p>\n

dataType[] arrayName = new dataType[arraySize];<\/p>\n

For example, to create an array of integers with a size of 5, you can write:<\/p>\n

csharp<\/p>\n

Copy code<\/p>\n

int[] myArray = newint[5];<\/p>\n

To access an element of an array, you can use the following syntax:<\/p>\n

csharp<\/p>\n

Copy code<\/p>\n

arrayName[index];<\/p>\n

For example, to access the third element of the “myArray” array, you can write:<\/p>\n

csharp<\/p>\n

Copy code<\/p>\n

int thirdElement = myArray[2];<\/p>\n

To create an ArrayList in C#, you can use the following syntax:<\/p>\n

csharp<\/p>\n

Copy code<\/p>\n

ArrayList arrayListName = new ArrayList();<\/p>\n

To add an element to an ArrayList, you can use the Add method:<\/p>\n

csharp<\/p>\n

Copy code<\/p>\n

arrayListName.Add(element);<\/p>\n

For example, to add an integer to an ArrayList, you can write:<\/p>\n

csharp<\/p>\n

Copy code<\/p>\n

arrayListName.Add(42);<\/p>\n

To access an element of an ArrayList, you can use the following syntax:<\/p>\n

csharp<\/p>\n

Copy code<\/p>\n

arrayListName[index];<\/p>\n

For example, to access the third element of an ArrayList, you can write:<\/p>\n

csharp<\/p>\n

Copy code<\/p>\n

int thirdElement = (int)arrayListName[2];<\/p>\n

Note that since ArrayList can store elements of different data types, you need to cast the retrieved element to the correct data type. In the above example, we cast the retrieved element to an integer using the (int) syntax.<\/p>\n
