我没学过VB，只是凭直觉看着这么改了一下，也没在VC#下编译，不知道正确与否 [所有相关帖子] 
using System.Data.Sqlclient;public class Catalog
{
    public SqlDataReader GetDepartments()
    {
        SqlConnection connection = new Sqlconnection(connectionString);
        SqlCommand command = new SqlCommand("GetDepartments", connection);
        
        command.CommandType = CommandType.StoredProcedure;
        connection.Open();
        
        return command.ExecuteReader(CommandBehavior.CloseConnection);
    }
    
    private string connectionString
    {
        get
        {
            return ConfigurationSettings.AppSettings("ConnectionString");
