我有一个解决方案,两个 MVC 3 应用程序共享同一个 DAL libaray。每个应用程序都指向不同的数据库,它们的连接字符串存储在各自的 web.config 文件中。

将他们的连接字符串传递给 DAL 的最佳方法是什么?

从 MVC 控制器:

string _connectionString = WebConfigurationManager.ConnectionStrings["NexGenContext"].ToString();
// Changes???
QuestionDAL qd = new QuestionDAL();
var agency = qd.SearchAgencies(ori, name)

DAL 代码:

public IEnumerable<AgencyTerm> SearchAgencies(string ori, string name)
        {
            log.Debug("Executing: SearchAgencies(string ori, string name)");
            List<AgencyTerm> agencies = new List<AgencyTerm>();
            using (var conn = new SqlConnection(_connectionString))
            {
                var com = new SqlCommand();
                com.Connection = conn;
                com.CommandType = CommandType.StoredProcedure;
                ... etc....

//添加构造函数

public QuestionDAL(string connectionString)
        {
            _connectionString = connectionString;
        }
