有人可以吗向我解释如何使用它并给我例子？我们如何阅读它？

“=>”是 lambda 运算符，读作“前往”
"=>" is lambda operator and is read as "goes to"
这就是 lambda 运算符。这意味着“去”。它用于创建 lambda 表达式，这是 C# 为匿名方法提供的语法。
例如。 lamda 表达式 x=>x > 2.。这意味着给定 x，x 会选择大于 2 的 x。换句话说，此 lambda 表达式将选择大于 2 的 x。
相同的匿名方法可以写为
This is the lambda operator. Which means 'goes to'. It is used to create lambda expressions which is syntax offered by C# for anonymous methods.

x=>x > 2. This mean that given x, x goes to x greater than 2. In other words this lambda expression will select x greater than 2.Anonymous method for the same can be written as
