.NET中的闭包

h2_lin>解决方案

C＃中的关闭内联代表/ 匿名方法的形式a>。 闭包附加到其父方法，意味着父项方法体中定义的变量可以从匿名方法中引用。在这里有一个伟大的博客。

示例

  public Person FindById （int id）
 {
 return this.Find（delegate（Person p）
 {
 return（p.Id == id）; 
} 
} 
  

您还可以查看 Martin Fowler 或 Jon Skeet 博客。我相信你将能够从他们中的至少一个得到更多的深度细分。

What are closures in C#?

解决方案

A closure in C# takes the form of an in-line delegate/anonymous method. A closure is 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 Post here about it.

Example

public Person FindById(int id)
{
    return this.Find(delegate(Person p)
    {
        return (p.Id == id);
    });
}

You could also take a look at Martin Fowler or Jon Skeet blogs. I am sure you will be able to get a more "In Depth" breakdown from at least one of them....
