int[] numbers = { 1, 2, 3, 4 }; double[] doubleNumbers = numbers.Cast().ToArray();
string[] words = { "hello", "world", "foo", "bar" }; string[] filteredWords = words.CastIn this example, we are first casting each element of the "words" array to a string using the Cast method. Next, we are using the Where method to filter out any elements that have a length less than or equal to 3. Finally, we are creating a new array containing only the filtered elements using the ToArray method. Package Library: The System.Array.Cast method is a part of the .NET Framework's System.Core library, which is included in the System.Core.dll assembly. Therefore, the package library for this method is System.Core.().Where(x => x.Length > 3).ToArray();
