#高级
##批量操作
批量操作将对应的dbcontext和数据进行分离由用户自己选择第三方框架比如zzz进行批量操作或者batchextension
```c#
virtualDbContext.BulkInsert<SysUserMod>(new List<SysUserMod>())
.BatchGroups.ForEach(pair =>
{
///zzz or other
pair.Key.BlukInsert(pair.Value);
});
var shardingBatchUpdateEntry = virtualDbContext.BulkUpdate<SysUserMod>(o => o.Id == "1", o => new SysUserMod()
{
Name = "name_01"
});
shardingBatchUpdateEntry.DbContexts.ForEach(context =>
{
//zzz or other
context.Where(shardingBatchUpdateEntry.Where).Update(shardingBatchUpdateEntry.UpdateExp);
});
```
# 最后
凭借各大开源生态圈提供的优秀代码和思路才有的这个框架,希望可以为.Net生态提供一份微薄之力,该框架本人会一直长期维护,有大神技术支持可以联系下方方式欢迎star :)
