What are 'closures' in C#?

A closurein C# takes the form of an in-line delegate/anonymous method. A closureis attached to its parent method meaning that variables defined in parent's method body can be referenced from within the anonymous method. There is a great Blog Posthere about it.
C# 中的闭包采用内联委托/匿名方法的形式。甲闭合连接到它的父方法意味着在父母的方法体定义的变量可以从匿名方法中被引用。这里有一篇很棒的博客文章。
Example:
例子：
public Person FindById(int id)
{
return this.Find(delegate(Person p)
{
return (p.Id == id);
});
}
You could also take a look at Martin Fowleror Jon Skeetblogs. I am sure you will be able to get a more "In Depth" breakdown from at least one of them....
您还可以查看Martin Fowler或Jon Skeet 的博客。我相信您将能够从其中至少一个中获得更“深入”的细分......
Example for C# 6:
C# 6 的示例：
public Person FindById(int id)
{
return this.Find(p => p.Id == id);
}
which is equivalent to
这相当于
public Person FindById(int id) => this.Find(p => p.Id == id);
