Array.AsReadOnly(T[]) Method in C#In this article, we will discuss the Array.AsReadOnly(T[]) method in C# with its syntax, parameter, and examples. What is the Array.AsReadOnly<T>(T[]) method?This method is used to return the read-only wrapper for the provided array. The Array is a helpful tool provided by the System, specifically the.NET framework in C#.The AsReadOnly(T[]) method.collections.ObjectModel is the namespace. With the help of this technique, we can provide an existing array for a read-only wrapper that offers an immutable and controlled view of the array's contents. Syntax:It has the following syntax: Parameters:
Exception:The method throws ArgumentNullException in the event that the array is null. Example 1:Let us take an example to illustrate the Array.AsReadOnly(T[]) method in C#. Output: Demonstrating LastIndexOf method... Array elements: car bike truck bus motorcycle Last occurrence of 'bus' is at index = 3 Example 2:Let us take another example to illustrate the Array.AsReadOnly(T[]) method in C#. Output: First element: 1 Elements: 1 2 3 4 5 Example 3:Let us take another example to illustrate the Array.AsReadOnly(T[]) method in C#. Output: Initial Array: Sunday Monday Tuesday Wednesday Thursday Friday Saturday Read-only Array: Sunday Monday Tuesday Wednesday Thursday Friday Saturday Conclusion:In conclusion, Array.AsReadOnly(T[]) is a useful method to create a read-only wrapper around an existing array in C#. Using this technique, developers can obtain an immutable view of the array's elements without making a duplicate of the original array. Its elements cannot be changed, safeguarding data integrity, and preventing accidental modifications because the array generates a read-only wrapper. As it implements IList and ICollection interfaces, the resulting read-only collection is compatible with methods and algorithms that require them. This method increases code safety and efficiency by providing an easy way to access array elements in a controlled and immutable manner. Array.AsReadOnly(T[]) is a vital tool for managing and interacting with arrays in C# applications. Next TopicDecimal.GetBits() Method in C# |
