管理员如何在ASP.NET核心中更改SQL Server中的数据？

services.AddDbContext<ApplicationDbContext>(options =>
    options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));

"ConnectionStrings": {
  "DefaultConnection": "Server=(localdb)\\mssqllocaldb;Database=YourDatabase;Trusted_Connection=True;MultipleActiveResultSets=true"
}

public class ApplicationDbContext : DbContext
{
    public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
        : base(options)
    {
    }

    public DbSet<YourModel> YourModels { get; set; }
}

private readonly ApplicationDbContext _context;

public YourController(ApplicationDbContext context)
{
    _context = context;
}

public IActionResult UpdateData()
{
    // 获取要更改的数据
    var data = _context.YourModels.FirstOrDefault();

    if (data != null)
    {
        // 修改数据
        data.Property = "New Value";

        // 保存更改
        _context.SaveChanges();
    }

    return RedirectToAction("Index");
}
