After studying it, I found that the system already has such functions. Dizzy !! Implement a method similar to func and action.Call example:Object inst = new program ();Decimal ret = Inst. Dynamic ("helloworld", guid. newguid (), 2009 );The source
Private Sub SetFocus (ByVal controltofocus as Control)
Dim Scriptfunction as New StringBuilder
Dim Scriptclientid as String
Scriptclientid = Controltofocus.clientid
Scriptfunction.append ("")
RegisterStartupScript ("Focus", scriptfunction.tostring ()
Dynamically generating a class is very helpful for technologies such as AOP,O/R mapping. For Java, it's not a big problem, but for. NET, it's a bit of a hassle (the main problem is that the generation of code needs IL), so it's probably also the
Earlier in the emit learning process, many times encountered the call to the method, found that sometimes use calls and sometimes the use of callvirt, has been not very understanding of the difference between the two. The MSDN is then reviewed and
Brief introduction
Understanding business processes, more agility, and near-real-time monitoring of management and compliance are growing business line requirements. Event-based Solutions support business and IT management enterprise risk by
In the previous blog ( say emit ), I described the basic technology implementation requirements, the difficulty and the scope of the target is very small, build a basic shelf. The only drawback to implementing the creation of assemblies, modules,
IL preliminary understanding, preliminary understanding of English
I. Overview:
Recently, I have been looking at AOP and learned that Emit can be implemented. Previous knowledge of Emit is part of the commands decompiled by Reflector. I will use

Analysis and utilization of a simple small program VulnerabilityBody
Note: readfile.exe is a vulnerability program that reads the c: \ overflow.txt file and pops up the file content in the form of a dialog box.

Signals (Singal) and slots (slots) are used to communicate with each other, signaling that when an event of an object occurs, a signal is triggered, a slot: the response to the specified signal, in fact the signal slot is similar. NET delegate,
topologies
The logic for a realtime application was packaged into a Storm topology. A Storm topology is analogous to a MapReduce job. One key difference is the a MapReduce job eventually finishes, whereas a topology runs forever (or until you kill
Shallow copy: when a reference member is copied, only the address referenced by the referenced member in the original object is copied to the new object, using the newly copied object,If you change the reference member within the value may be will
When developing with Dapper and sqlce, if a field in the database is the ntext data type used, and the data stored in this field exceeds 4,000 characters, the following error is reported:
Invalid parameter Size value '-1 '. The value must
IL interface and class attributes, IL interface attributes
In the previous article, I learned how to get started with IL. Next, I will use two examples to understand the attributes, constructor, and Interface Usage of the class.

Sometimes the whole project architecture also needs to dynamically create the assembly, so how to create the Assembly, please come with me to learn.
First, you need to know what technologies are used to dynamically create these types? In fact, as

There are many forms of hook. Here we analyze the inline HOOK API
This type of hook only targets the process to be hooked, and does not affect other processes.
For example, a process uses the MessageBox API,

I have been learning Emit recently and have some knowledge about commands. I have summarized some small experiences in the frequent use of commands in IL.
It is to push the variables, parameters to the stack, and then call some methods. This will be
