您要查找的是不是:
- For starters, the brevity of the lambda expression can be attributed to a number of factors. 对于初学者而言,lambda表达式简明扼要的原因有很多。
- This makes it possible to pass a lambda expression as a parameter without explicitly assigning it to a delegate. 这样能以参数形式传递lambda表达式,而不用显式将其分配给委托。
- The underlying type of a lambda expression is one of the generic Func delegates. Lambda表达式的基础类型是泛型Func委托之一。
- The lambda expression returns true if the length of the String parameter is equal to the value of the Int32 parameter. 如果String参数的长度等于Int32参数的值,则此lambda表达式将返回true。
- The body of a lambda expression can be an expression or a statement block whereas the body of an anonymous method can only be a statement block. 表达式的主体可以是一个表达式或者是一个声明块,而匿名函数的主体只能是声明块。
- Even if it is an instance method, the above does not compile, because a lambda expression cannot be passed as an argument to a dynamic operation. 即便它是一个实例方法,上面的代码也无法编译,因为lambda表达式不能作为参数传递给动态操作。
- In particular, because many methods of types in the System.Linq namespace have Func parameters, you can pass these methods a lambda expression without explicitly instantiating a Func delegate. 尤其是;因为System.;Linq命名空间中许多类型方法具有[Func]参数;因此可以给这些方法传递lambda表达式;而不用显式实例化[Func]委托。
- Lambda expressions, an evolution of anonymous methods that provides improved type inference and conversions to both delegate types and expression trees. Lambda表达式,匿名函数的一种进化,为代理类型和表达式树提供改良的类型推断结果和转换。
- Lambda expressions are a language feature that is similar in many ways to anonymous methods. Lambda表达式是一种语言功能,在许多方面类似于匿名方法。
- Lambda expressions in an argument list affect overload resolution in certain situations. 参数列表中的Lambda表达式在某些条件下影响重载决议。
- Lambda expressions passed as arguments to the generic method participate in this type inference process. Lambda表达式传递参数到泛型函数,且参与这次类型推断的过程。
- In this initial phase, nothing is inferred from arguments that are lambda expressions. 在初始阶段,不能从lambda表达式参数推导出任何东西。
- In fact, if lambda expressions had been put into the language first, there would have been no need for anonymous methods. 事实上,如果lambda表达式首先被引入语言,那么就不会有对匿名方法的需要了。
- Finally, Lambda expressions support a more verbose syntax that allows you to specify the types explicitly, as well as execute multiple statements. 最后,Lambda表达式支持更冗长的语法,允许您显式指定类型,以及执行多条语句。
- Lambda expressions permit parameter types to be omitted and inferred whereas anonymous methods require parameter types to be explicitly stated. 表达式允许参数类型被省略掉和被推导,尽管匿名方法要求显式指定参数类型。
- An expression of pain flitted across her face. 她脸上闪过一种痛苦的表情。
- He always shows a doleful expression. 他总是露出忧郁的表情。
- I can think of no greater expression of defeatism. 这是我听到的最悲观的失败主义论调了。
- A constant, variable, function name, or expression. 一种常数、变量、函数名或表达式。
- She looked at me without expression. 她毫无表情地朝我看着。
