在linq中有没有一种方法可以使用over with order by子句?

也许这可以奏效:

已编辑(我已经尝试了您的查询,我认为这是您正在寻找的)

List<TableName> tableNames = new List<TableName> {
    new TableName { Number = 2},
    new TableName { Number = 4},
    new TableName { Number = 3},
    new TableName { Number = 3},
    new TableName { Number = 2},
    new TableName { Number = 3},
    new TableName { Number = 4},
    new TableName { Number = 4},
    new TableName { Number = 4},
    new TableName { Number = 4}
};

IEnumerable<int> runningSum = tableNames.Select(r => (tableNames.Where(ri => ri.Number <= r.Number).Sum(rii => rii.Number))).OrderBy(num => num);

结果:

4
4
13

13
33
