C# 是否有与 ActiveRecord#find_by 等效的等效项？
我最初是一名 C# 开发人员（作为一种爱好），但最近我一直在深入研究 Ruby on Rails，并且非常喜欢它。现在我正在用 C# 构建一个应用程序，我想知道 C# 是否有任何集合实现可以匹配（或“半匹配”）ActiveRecord 的 find_by 方法。
我本质上要寻找的是一个包含矩形的列表：
class Rectangle
{
public int Width { get; set; }
public int Height { get; set; }
public string Name { get; set; }
}
我可以在其中查询此列表并查找Height = 10，Width = 20<的所有条目/code> 或 name = "Block"。这是通过 ActiveRecord 进行类似于 Rectangle.find_by_name('Block') 的调用来完成的。我能想到的在 C# 中执行此操作的唯一方法是创建我自己的列表实现，并迭代每个项目，根据条件手动检查每个项目。我担心我会重新发明轮子（而且质量较差）。
我不一定要尝试匹配命名约定 find_by_...，而是要具有该方法的功能。
非常感谢任何意见或建议。
I'm originally a C# developer (as a hobby), but as of late I have been digging into Ruby on Rails and really enjoying it. Right now I am building an application in C#, and I was wondering if there is any collection implementation for C# that could match (or "semi-match") the find_by method of ActiveRecord.
What I am essentially looking for is a list that would hold Rectangles:
class Rectangle
{
public int Width { get; set; }
public int Height { get; set; }
public string Name { get; set; }
}
Where I could query this list and find all entries with Height = 10, Width = 20, or name = "Block". This was done with ActiveRecord by doing a call similar to Rectangle.find_by_name('Block'). The only way I can think of doing this in C# is to create my own list implementation and iterate through each item manually checking each item against the criteria. I fear I would be reinventing the wheel (and one of poorer quality).
I am not necessarily trying to match the naming convention find_by_..., but rather to have the functionality of the method.
Any input or suggestions is much appreciated.

“Linq 方法”，即添加在 . NET 3.5 非常接近您正在寻找的东西。
The "Linq methods", namely Where, that were added in .NET 3.5 are pretty close to what you're looking for.
