linq-to-sql - 将 SQL 转换为 LINQ 到 SQL

Question

我在将以下 SQL 转换为 LINQ to SQL 时遇到了很大的麻烦，有人能帮忙吗？

SELECT     dbo.ExpensesGroup.ExpenseGroupId, dbo.ExpensesGroup.Title, SUM(dbo.Expenses.Amount) AS TotalAmount, MAX(dbo.Expenses.DateLastTickled) 
                      AS LastTickledDate, MAX(dbo.ExpensesGroup.DateTime) AS Date, Username
FROM         dbo.Expenses INNER JOIN
                      dbo.ExpensesGroup ON dbo.Expenses.ExpenseId = dbo.ExpensesGroup.ExpensesId
WHERE     dbo.Expenses.Status = 'AwaitingApproval' or dbo.Expenses.Status = 'AwaitingApprovelGrouping'
GROUP BY dbo.ExpensesGroup.ExpenseGroupId, dbo.ExpensesGroup.Title, dbo.Expenses.Username
ORDER BY MAX(dbo.ExpensesGroup.DateTime) DESC, dbo.ExpensesGroup.Title

或者甚至更好的人知道自动 SQl 到 LINQ 转换器？

如果您决定手工制作，Linqpad应该有用。
