c# - 刷新 EntityFramework 连接

Question

我正在 App.config 中更改 EntityFramework 连接字符串，如下所示:

        var connectionString = new SqlConnectionStringBuilder(entityConnectionString.ProviderConnectionString);

        connectionString.UserID = dbUser;
        connectionString.Password = dbPass;
        connectionString.InitialCatalog = dbCatalog;
        connectionString.DataSource = dbServer;

        entityConnectionString.ProviderConnectionString = connectionString.ToString();

        cString.ConnectionString = entityConnectionString.ToString();

        conf.Save(ConfigurationSaveMode.Full);
        ConfigurationManager.RefreshSection("connectionStrings");

但是 EntityFramework 继续使用旧的连接设置，直到应用程序重新启动。有没有办法强制 EntityFramework 从 App.config 获取新的连接字符串？

我相信特拉维斯是对的。这是我用来执行此操作的代码:

public void RefreshContext(string myConnectionString)
{
  DisposeContext();
  Context = new MyContext(myConnectionString);
}

public void DisposeContext()
{
  if (Context == null)
    return;
  Context.Dispose();
}
