如何在MVC中使用EF更新数据库中的记录？

using System.Data.Entity;

private YourDbContext db = new YourDbContext();

var entity = db.YourEntities.Find(id);
entity.Property1 = newValue1;
entity.Property2 = newValue2;

db.SaveChanges();

using System.Data.Entity;

public class YourController : Controller
{
    private YourDbContext db = new YourDbContext();

    // ...

    public ActionResult Update(int id, string newValue1, string newValue2)
    {
        var entity = db.YourEntities.Find(id);
        entity.Property1 = newValue1;
        entity.Property2 = newValue2;

        db.SaveChanges();

        // 返回更新后的视图或其他操作
    }

    // ...
}
