虽然Code First Database Evolution尚未提供,但即使在开发期间,我仍希望在我的数据库中保留一些基本数据。我的想法是将数据保存在备份数据库中,并在初始化时自动将其读取到数据库中。
是否可以做这样的事情?
class MyInitializer : DropCreateDatabaseIfModelChanges<MyDatabase>
{
protected override void Seed(MyDatabase context)
{
var questions = new List<Question>
{
foreach(var row in MySecondDataSource)
{
new Question
{
QuestionID = row.Column["a"]
QuestionText = row.Column["b"],
SortOrder = row.Column["c"],
QuestionType = questionTypes.Find(q => q.QuestionTypeID == row.Column["d"]),
Category = categories.Find(c => c.CategoryID == row.Column["e"]),
Target = targets.Find(t => t.TargetID == row.Column["f"]),
Unit = units.Find(u => u.UnitID == row.Column["g"])
};
}
};
questions.ForEach(q => context.Questions.Add(q));
关于如何在放弃数据后保存或重新输入数据的任何其他想法?
