C# | Get value of the bit at a specific position in BitArray Last Updated : 01 Feb, 2019 Comments Improve Suggest changes Like Article Like Report The BitArray class manages a compact array of bit values, which are represented as Booleans, where true indicates that the bit is on i.e, 1 and false indicates the bit is off i.e, 0. This class is contained in System.Collections namespace. BitArray.Get(Int32) method is used to get the value of the bit at a specific position in the BitArray. Properties: The BitArray class is a collection class in which the capacity is always the same as the count. Elements are added to a BitArray by increasing the Length property. Elements are deleted by decreasing the Length property. Elements in this collection can be accessed using an integer index. Indexes in this collection are zero-based. Syntax: public bool Get (int index); Here, index is the zero-based index of the value to get. Return Value: It returns the value of the bit at position index. Exception: This method will give ArgumentOutOfRangeException if the index is less than zero or index is greater than or equal to the number of elements in the BitArray. Below given are some examples to understand the implementation in a better way: Example 1: CSHARP // C# code to get the value of // the bit at a specific position // in the BitArray using System; using System.Collections; class GFG { // Driver code public static void Main() { // Creating a BitArray BitArray myBitArr = new BitArray(5); myBitArr[0] = true; myBitArr[1] = true; myBitArr[2] = false; myBitArr[3] = true; myBitArr[4] = false; // To get the value of index at index 2 Console.WriteLine(myBitArr.Get(2)); // To get the value of index at index 3 Console.WriteLine(myBitArr.Get(3)); } } Output: False True Example 2: CSHARP // C# code to get the value of // the bit at a specific position // in the BitArray using System; using System.Collections; class GFG { // Driver code public static void Main() { // Creating a BitArray BitArray myBitArr = new BitArray(5); myBitArr[0] = true; myBitArr[1] = true; myBitArr[2] = false; myBitArr[3] = true; myBitArr[4] = false; // To get the value of index at index 6 // This should raise "ArgumentOutOfRangeException" // as index is greater than or equal to // the number of elements in the BitArray. Console.WriteLine(myBitArr.Get(6)); } } Runtime Error: Unhandled Exception: System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index Example 3: CSHARP // C# code to get the value of // the bit at a specific position // in the BitArray using System; using System.Collections; class GFG { // Driver code public static void Main() { // Creating a BitArray BitArray myBitArr = new BitArray(5); myBitArr[0] = true; myBitArr[1] = true; myBitArr[2] = false; myBitArr[3] = true; myBitArr[4] = false; // To get the value of index at index -2 // This should raise "ArgumentOutOfRangeException" // as index is less than zero. Console.WriteLine(myBitArr.Get(-2)); } } Runtime Error: Unhandled Exception: System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index Note: This method is an O(1) operation.
