GroupBy vb.net和c#之间的差异

本文关键字:之间 vb net GroupBy | 更新日期: 2023-09-27 18:20:51

我学习了一个用c#编写代码的linq教程,并尝试将代码片段翻译成vb.net

var employeeGroups = from employee  in Employee.GetAllEmployees()
                     group employee by employee.Deptartment;

我可以把它翻译成扩展方法

Dim group1 = Employee.GetAllEmployees.GroupBy(Function(x) x.Department)

工作正常,但

Dim group = From emp In Employee.GetAllEmployees
            Group emp By emp.Department

给了我一个编译错误"into expected"。我找不到任何关于它的信息,但我必须在vb中使用"INTO",而不是在c#中,这对吗?如果是这样,我必须如何调整我的查询以适应c#等价物?

GroupBy vb.net和c#之间的差异

VB.Net具有不同的组语法。试试这个。。

From emp In Employee.GetAllEmployees
         Group By Department= emp.Department Into g = Group
         Select g

或者简单的

From emp In Employee.GetAllEmployees
             Group By Department= emp.Department Into Group
