int input = Console.ReadInt32();
using System.IO; ... string fileName = "data.txt"; int[] data = new int[10]; using (StreamReader file = new StreamReader(fileName)) { for (int i = 0; i < data.Length; i++) { data[i] = file.ReadInt32(); } }In this example, the ReadInt32 method is used to read integer values from a text file called 'data.txt'. The values are stored in an array for later use. Package library: The System ReadInt32 method is part of the System namespace, which is included in the .NET Framework Class Library.
