using System; using System.Data.SqlClient; namespace DataAccessExceptionExample { class Program { static void Main(string[] args) { string connectionString = "Data Source=myServerAddress;Initial Catalog=myDataBase;User Id=myUsername;Password=myPassword;"; try { using SqlConnection connection = new SqlConnection(connectionString); connection.Open(); Console.WriteLine("Connected successfully!"); } catch (Exception ex) { Console.WriteLine($"Error: {ex.Message}"); } } } }
using System; using System.IO; namespace DataAccessExceptionExample { class Program { static void Main(string[] args) { try { string filePath = @"C:\Program Files\MyApp\myDataFile.txt"; using StreamReader streamReader = new StreamReader(filePath); string fileContent = streamReader.ReadToEnd(); Console.WriteLine($"File content: {fileContent}"); } catch (Exception ex) { Console.WriteLine($"Error: {ex.Message}"); } } } }In this example, the file is being accessed from the Program Files directory, which requires elevated privileges. As a result, the Data AccessDenied exception is thrown. The package library for working with Data AccessDenied exceptions in C# could be the System.Data.SqlClient or System.IO namespaces, depending on the type of resource being accessed.
