Question

I’ve got a simple table:
Year – Quarter – Value
2012 1 177
2012 2 213
2012 3 168
2012 4 313

I want to return the data via Linq as this:

Year – Q1 – Q2 – Q3 – Q4
2012 177 213 168 313

Any suggestions on the best way to do this? I assume some sort of Pivot?

TIA

Answer 1

This is what I worked out:

 Metrics.GroupBy(c => c.Year) 
 .Select(g => new {
Year = g.Key,
Q1 = g.Where(c => c.Quarter == 1).Sum(c => c.Value), 
      Q2 = g.Where(c => c.Quarter == 2).Sum(c => c.Value), 
Q3 = g.Where(c => c.Quarter == 3).Sum(c => c.Value),
Q4 = g.Where(c => c.Quarter == 4).Sum(c => c.Value) 
})

Any better suggestions?
