C# ASP.net c LINQ for循环

q.LabelID不起作用，我不能真正使用foreach，因为我必须在每次迭代中调用新的ArtworkLabel。

这将起作用：

// Load all the links
ArtworkingDataContext dc = new ArtworkingDataContext();
var q = (from Labels in dc.tblArtworkLabels where Labels.templateID == this.ID select new { LabelID = Labels.ID });

// Create labels array
this.Labels = new ArtworkLabel[q.Count()];
for (int i = 0; i < q.Count(); i++)
{
    this.Labels[i] = new ArtworkLabel(q.LabelID);
}

ArtworkingDataContext dc = new ArtworkingDataContext();
this.Labels = (from Labels in dc.tblArtworkLabels where Labels.templateID == this.ID select new ArtworkLabel(Labels.ID)).ToArray();

这将有助于：

// Load all the links
ArtworkingDataContext dc = new ArtworkingDataContext();
var q = (from Labels in dc.tblArtworkLabels where Labels.templateID == this.ID select new { LabelID = Labels.ID });

// Create labels array
this.Labels = new ArtworkLabel[q.Count()];
for (int i = 0; i < q.Count(); i++)
{
    this.Labels[i] = new ArtworkLabel(q.LabelID);
}

ArtworkingDataContext dc = new ArtworkingDataContext();
this.Labels = (from Labels in dc.tblArtworkLabels where Labels.templateID == this.ID select new ArtworkLabel(Labels.ID)).ToArray();

试着这样做：

this.Labels = dc.tblArtworkLabels
                .Where( x=> x.templateId == this.Id)
                .Select( x=> new ArtworkLabel(x.ID))
                .ToArray();

ArtworkingDataContext dc = new ArtworkingDataContext();
this.Labels = (from Labels in dc.tblArtworkLabels where Labels.templateID == this.ID select new ArtworkLabel(Labels.ID)).ToArray();

试着这样做：

this.Labels = dc.tblArtworkLabels
                .Where( x=> x.templateId == this.Id)
                .Select( x=> new ArtworkLabel(x.ID))
                .ToArray();

ArtworkingDataContext dc = new ArtworkingDataContext();
this.Labels = (from Labels in dc.tblArtworkLabels where Labels.templateID == this.ID select new ArtworkLabel(Labels.ID)).ToArray();

你可以这样做，对吗

this.Labels = q.Select(x => new ArtworkLabel(x.LabelID)).ToArray();

ArtworkingDataContext dc = new ArtworkingDataContext();
this.Labels = (from Labels in dc.tblArtworkLabels where Labels.templateID == this.ID select new ArtworkLabel(Labels.ID)).ToArray();

this.Labels = q.Select(x => new ArtworkLabel(x.LabelID)).ToArray();

ArtworkingDataContext dc = new ArtworkingDataContext();
this.Labels = (from Labels in dc.tblArtworkLabels where Labels.templateID == this.ID select new ArtworkLabel(Labels.ID)).ToArray();

您应该能够在一个linq语句中完成这一切

ArtworkingDataContext dc = new ArtworkingDataContext();

this.Labels = 
    from label in dc.tblArtworkLabels 
    where label.templateID == this.ID
    select new ArtworkLabel(label.ID).ToArray();

ArtworkingDataContext dc = new ArtworkingDataContext();
this.Labels = (from Labels in dc.tblArtworkLabels where Labels.templateID == this.ID select new ArtworkLabel(Labels.ID)).ToArray();

ArtworkingDataContext dc = new ArtworkingDataContext();

我最近试过这个，一个linq for循环。。这就是我想到的

ArtworkingDataContext dc = new ArtworkingDataContext();
this.Labels = (from Labels in dc.tblArtworkLabels where Labels.templateID == this.ID select new ArtworkLabel(Labels.ID)).ToArray();
