GroupBy vb.net和c#之间的区别

Question

我正在使用linq教程,其中代码是用c#编写的,并尝试将片段翻译成vb.net.以下是在c#下工作:

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)

工作得很好但是

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

给我一个编译错误'进入预期'.我无法找到任何关于它的信息,但是它是正确的,我必须在vb中使用'INTO'而不是在c#中使用它？如果是这样,我如何调整我的查询以适应c#aquivalent？

Answer 1

VB.Net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

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