敬请参考以下解决方法:
Include
方法来显式加载相关数据。var customers = await context.Customers.Include(c => c.Orders).ToListAsync();
Skip
和Take
方法来实现分页加载。var customers = await context.Customers.Skip(pageSize * (pageIndex - 1)).Take(pageSize).ToListAsync();
MemoryCache
或其他缓存库来缓存查询结果。var customers = await cache.GetOrCreateAsync("customers", entry =>
{
entry.AbsoluteExpirationRelativeToNow = TimeSpan.FromMinutes(10);
return context.Customers.ToListAsync();
});
Include
方法来预加载相关数据,或者使用ThenInclude
方法来加载多级关联数据。var customers = await context.Customers.Include(c => c.Orders).ThenInclude(o => o.Items).ToListAsync();
var customers = await context.Customers.ToListAsync();
以上是一些常见的解决方法,具体的解决方案可能因情况而异。如果问题仍然存在,建议使用性能分析工具来查找性能瓶颈并优化代码。
