Can we add variables and properties in interfaces in C#.NET?
提问by Kiran Thokal
I want to know that how to add variables (i.e. with which access specifier) in interfaces and also can we write property in interfaces in C#.net?
我想知道如何在接口中添加变量（即使用哪个访问说明符）以及我们是否可以在 C#.net 的接口中编写属性？

This should have been easy to find on the internet.
这应该很容易在互联网上找到。
Interfaces are contracts to be fulfilled by implementing classes. Hence they can consist of publicmethods, properties and events (indexers are permitted too).
接口是通过实现类来实现的契约。因此它们可以由公共方法、属性和事件组成（也允许索引器）。
Variables in Interfaces - NO. Can you elaborate on why you need them? You can have variables in Base classes though.
Properties in Interfaces - Yes, since they are paired methods under the hood.
Members of an interface are implicitly public. You cannot specify access modifiers explicitly
接口中的变量 - 否。你能详细说明你为什么需要它们吗？不过，您可以在基类中使用变量。
接口中的属性 - 是的，因为它们在幕后是成对的方法。
接口的成员是隐式公开的。您不能显式指定访问修饰符
public interface ISampleInterface
{
// method declaration
bool CheckSomething(object o);
// event declaration
event EventHandler ShapeChanged;
// Property declaration:
string Name
{
get;
set;
}
}

Variables in interfaces, I don't think so but I'm not 100% certain?
接口中的变量，我不这么认为，但我不是 100% 确定？
And yes, you can have properties in interfaces. See the MSDN reference:
Interface Properties (C# Programming Guide)
是的，您可以在接口中拥有属性。请参阅 MSDN 参考：
接口属性（C# 编程指南）
