在LINQ中是否有与SQL Server PARTITION OVER功能相当的功能？

Question

LINQ中是否存在SQL Server PARTITION OVER功能的等效项？

SELECT Decision_ID , 
     ID 
     ROW_NUMBER() OVER (PARTITION BY Decision_ID 
          ORDER BY Decision_ID, ID ASC) calcAmend 
FROM dbo.Decision_Data 

这给每个记录

Answer 1

DecisionData 
    .GroupBy(d => d.DecisionID, 
     (key, dd) => dd 
        .OrderBy(d => d.Id) 
        .Select((d, i) => new {d.DecisionId, d.Id, calcAmend = i})) 
    .SelectMany(d => d)
