如何使用 Lambda 将 LINQ Comprehension 查询语法转换为方法语法 [英] How to Convert LINQ Comprehension Query Syntax to Method Syntax using Lambda

问题描述

是否有工具、流程或解决方案可以将以下 LINQ 查询语法转换为使用 Lambda 的方法语法(点表示法)?我希望解决方案将以下查询语法转换为这样的方法语法.

Is there a tool, process or a solution that will convert the following LINQ Query Syntax to Method Syntax with Lambdas (dot notation)? I would expect the solution to convert the following Query Syntax to a Method Syntax such as this.

var filteredEmployees = 
    from employee in allEmployees
    where employee.DepartmentID < 4 && employee.EmployeeID < 10
    orderby employee.DepartmentID descending,
            employee.LastName descending
    select employee;

以下内容

var filteredEmployees2 = allEmployees.Where(employee => ((employee.DepartmentID < 4) && (employee.EmployeeID < 10)))
        .OrderByDescending(employee => employee.DepartmentID)
        .ThenByDescending(employee => employee.LastName);

我想用它来更好地学习方法语法.

I'm would like to use this to learn Method Syntax better.

LINQPad 是一个很好的工具你需要.我从他们的网站窃取"了以下屏幕截图，以更好地说明它是如何工作的.如果您使用 linq 语法编写查询，则可以单击以红色突出显示的按钮以查看等效的 lambda 语法:

LINQPad is a good tool for what you need. I "stole" the following screenshot from their website to better illustrate how it works. If you write a query using linq syntax you can click on the button highlighted in red to see the equivalent lambda syntax:
