Amazing decimal, maybe I will ask during the interview ~, Decimal interview
As busy as a dog during this time, blog writing will be delayed and we will continue to talk about it. Why is decimal magic? We all know that decimal is a primitive type,
This decimal type does not have corresponding IL commands in IL. That is to say, CLR does not know decimal at all. This layer of the compiler is fooling us.
Let's
other procedures from modifying counter variables. This is similar to object encapsulation. It should have been a local variable of a method. Now I want to be forced to separate it. It is obviously not a good design. So how does VB generate local static variables? ReplaceCodeIn the back-to-assembly process, we can clearly see that in the WordPress generated by VB, I is not a local variable, but a field of the class:
. Field private specialname int32 $ static $ test1 $2001 $ I

In the past, when developing a system, we always had to decide what to use.Programming Language. This is a difficult task because different languages have different capabilities. However, since the emergence of. net, the problem has been solved. Let's take a look at the figure below.
The Common Language Runtime (CLR) is a Runtime Library that can be u
dll with Reflector, we found that the class name and function name were changed to strings with many numbers, and the original name became totally different.
This must be the dll processed by the obfuscator. Since the function name and class name have changed, the source code output through Reflector is also composed of numbers and letters, and it is useless to re-compile the program, I had to find some ideas and methods.
Then I thought of another idea.. net Program (exe or dll) decomcompiled

CLR (Common Language Runtime): A "RunTime" that can be used by multiple programming languages ";
During runtime, CLR does not care which language is used by developers to change code. It only focuses on whether the language is oriented to CLR (runtime.2: Core CLR functions include:
Memory Management, assembly loading, security, exception handling, and thread synchronization.

So how does VB generate local static variables? By returning the code back to the assembly, we can clearly see that I was not a local variable in VB-generated CIL, but rather as a field of the class:
. field Private specialname int32 $STATIC $test1$2001$i
In other words, I was renamed as a class field, but was dubbed
.• Finally, return the address of the object that has become the reference type.
The following is the simplest Packing code line.
1 object obj = 1;
This line of statements assigns the integer constant 1 to the object type variable obj. It is well known that constant 1 is a value type, the value type is to be placed on the stack, and the object is a reference type, it needs to be placed on the stack; to put the value type on the stack, You need to perform a packing operation.
