Sheepaspect Introduction and Code Listing:

Sheepaspect is an AOP framework for the. NET platform, deeply aspectj. It statically weaves the target component as a compiled task (the AOP code is implanted at compile time).

When there are many characteristics, you can set the sequential order according to the parameter value.

The following begins the Code implementation tour:

First, the new console program: scheme name: sheepaecttest

Second, NuGet search sheepaspect for installation

Three, after the installation of the appearance

The entry type of the member (Selectmethdos):

"SAQL":

Criteria	Argument	Examples
Name	String	Name: ' *customer ' Name: (' *service ' | ' *repository ')
Namespace	String	! Namespace: ' system.* '
Implementstype	Type Pointcut	Implementstype: ' System.Collections.IEnumerable ' Implementstype: (Name: ' *repository ' | Namespace: ' *. Datacontexts ')
Assignabletotype	Type Pointcut	Assignabletotype: (' system.collections.* ' & Interface) Assignabletotype:namespace: ' system.collections.* '
Hasmethod	Method Pointcut	Hasmethod:name: ' get* ' Hasmethod: (Public & Args (' System.Int32 ')
Hasproperty	Property Pointcut	Hasproperty:name: ' Length ' HasProperty:Type:Implements: ' *.*service '
Hasfield	Field Pointcut	Hasfield:name: (' _createddate ' | ' _entrydate ') Hasfield: ((Public & Static) | Protected)

interface*	(none)	Interface ! Interface
abstract*	(none)	Abstract & Name: ' *strategy '
valuetype*	(none)	ValueType & hasmethod:name: ' Equals '
class*	(none)	Class & Implements: ' Sheep.irepository '

Attributes are implanted in the following columns:

First, new features

    Public class Logattribute:attribute    {        publicstringgetset;}          Public Logattribute (string  name)        {            = name;        }    }

Second, a new test class TestClass.cs

    public class TestClass    {        [Log (first method obtained]] public        string Get ()        {            return "test1";        }        public string Get2 ()        {            return ' test2 ';        }    }

Third, change Sampleaspect to: hascustomattributetype: ' SheepAectTest.Attr.LogAttribute ' > namespace + class name

Four: Write the test code:

Output Result:

What if we change the results in AOP?

Output Result:

To get the properties of an attribute:

  [Aspect]    public class Sampleaspect    {        [Selectmethods ("Hascustomattributetype: ' SheepAectTest.Attr.LogAttribute '")] Public        void Publicmethods () {}        [Around ("publicmethods", priority = +)]        public Object Logaroundmethod (methodjointpoint jp)        {            try            {                var log = (Logattribute) JP. Method.getcustomattributes (typeof (Logattribute), false) [0];                This allows you to get the property name: Log. Name;                Jp. Args  --Contains the pass parameter                var result = JP. Execute ();                if (JP. Method.returntype = = typeof (void))                    result = "{void}";                result = "AOP change result";                return result;            }            catch (Exception e)            {                throw;            }        }    }

　　

Multiple attribute Injection order: The Priority attribute value controls the lower precedence value;
