# Express AOP
[](https://www.nuget.org/packages/expressaop)
[](https://ci.appveyor.com/project/chsword/expressaop)
### NuGet Install
``` powershell
PM> Install-Package ExpressAOP
```
### Test case
You can define a fillter like this:
```c#
public class MyFilter : AOPFilterAttribute
{
private readonly string _key;
public MyFilter(String key)
{
_key = key;
}
protected override void Executing(IProcesser processer)
{
Setting.List.Add("Executing-" + _key);
}
protected override void Executed(IProcesser processer)
{
Setting.List.Add("Executed-" + _key);
}
}
```
eg: You have a class like following:
```c#
class MyClass {
public void Foo1()
{
}
}
```
And you want the filter is working on the Method.
You have 2 methods to use the filter;
### 1.Use the ContextBoundObject baseclass
```c#
[AOPProxy]// Use the AOP
class MyModel2 : ContextBoundObject// baseclass
{
[MyFilter(":filter")]//AFilter
public void Foo1()
{
Setting.List.Add("method");
}
}
```
I write a test case for this way:
```c#
[TestMethod]
public void ClassContextBoundObject()
{
var o = new MyModel2();
o.Foo1();
Assert.AreEqual(new[]
{
"Executing-:filter",
"method",
"Executed-:filter"
}.GetStr(), Setting.List.GetStr());
}
```
It'll be working well.
### 2.Use the Interface
You must impl a interface for your class
```c#
public interface IMyModel
{
void Foo(int i);
}
public class MyModel : IMyModel
{
private readonly string _key;
public MyModel(string key)
{
_key = key;
}
[MyFilter("method:filter")]
public void Foo(int i)
{
Setting.List.Add("method-foo-" + _key);
}
}
```
And use this code:
```c#
var proxy = new AOPProxy(new MyModel("1"));
var obj = proxy.GetObject();
obj.Foo(1);
```
It'll be running.
### 3.Other
You can use Filter like this:
```c#
[MyFilter("I:filter")]
public interface IMyModel
{
[MyFilter("I-Method1:filter")]
[MyFilter("I-Method2:filter")]
void Foo(int i);
string MyProperty
{
[MyFilter("I-prop-get:filter")]
get;
}
}
[MyFilter("class:filter")]
public class MyModel : IMyModel
{
private readonly string _key;
public MyModel(string key)
{
_key = key;
}
[MyFilter("method:filter")]
public void Foo(int i)
{
Setting.List.Add("method-foo-" + _key);
}
public string MyProperty
{
[MyFilter("prop-get:filter")]
get
{
Setting.List.Add("prop-ins-" + _key);
return _key;
}
}
}
```
Execute Order is
Order | Description
------------- | -------------
1 | The Filter on Interface
2 | The Filter on Class
3 | The Filter on Interface's Method or Property
4 | The Filter on Class 's Method or Property
5 | Method or Property
