我有以下代码。该函数有很多 Linq 调用,我在将其落实到位时得到了帮助。
public IList<Content.Grid> Details(string pk)
{
IEnumerable<Content.Grid> details = null;
IList<Content.Grid> detailsList = null;
var data = _contentRepository.GetPk(pk);
var refType = this.GetRefType(pk);
var refStat = this.GetRefStat(pk);
var type = _referenceRepository.GetPk(refType);
var stat = _referenceRepository.GetPk(refStat);
details =
from d in data
join s in stat on d.Status equals s.RowKey into statuses
from s in statuses.DefaultIfEmpty()
join t in type on d.Type equals t.RowKey into types
from t in types.DefaultIfEmpty()
select new Content.Grid
{
PartitionKey = d.PartitionKey,
RowKey = d.RowKey,
Order = d.Order,
Title = d.Title,
Status = s == null ? null : s.Value,
StatusKey = d.Status,
Type = t == null ? null : t.Value,
TypeKey = d.Type,
Link = d.Link,
Notes = d.Notes,
TextLength = d.TextLength
};
detailsList = details
.OrderBy(item => item.Order)
.ThenBy(item => item.Title)
.Select((t, index) => new Content.Grid()
{
PartitionKey = t.PartitionKey,
RowKey = t.RowKey,
Row = index + 1,
Order = t.Order,
Title = t.Title,
Status = t.Status,
StatusKey = t.StatusKey,
Type = t.Type,
TypeKey = t.TypeKey,
Link = t.Link,
Notes = t.Notes,
TextLength = t.TextLength,
})
.ToList();
return detailsList;
}
第一个对 Linq 使用一种格式,第二个使用另一种格式。有什么方法可以简化和/或组合这些吗?我真的很想让这段代码更简单,但我不知道该怎么做。任何建议将不胜感激。
