C # Assembly series 02. use NotePad to view the IL code of the executable assembly,

Continue to the previous article "C # Assembly series 01, write C # And IL code in notepad, compile the Assembly with the DOS command, and run the program". There are already several assemblies in the as folder of the F disk. In this article, use NotePad to view the IL code of the executable assembly.

 

→ Open "VS2012 developer command prompt", enter the following command, and press ENTER

Add the 1.txt and 1. res files to the asfile folder.
For example, to open 1.txt

Above,

○. Assembly extern mscorlib indicates that the. NET default assembly mscorlib needs to be referenced during CLR running.
○. Assembly extern MyClass, indicating that the custom assembly MyClass needs to be referenced during CLR operation
○. Assembly MainClass statement block, including the Manifest list of the MainClass assembly
○. Module mainclass.exe, mainclassthis program set has a modulenamed mainclass.exe. Of course, an assembly can contain multiple modules

 

"C # Assembly series" includes:

C # Assembly series 01, use NotePad to write C # And IL code, use the DOS command to compile the assembly, and run the C # Assembly series 02 program, use NotePad to view the IL code C # Assembly series 03 of the executable assembly, reference multiple module C # Assembly series 04, understand the keyword internal C # Assembly generation 05 when the Assembly contains multiple modules, so that the Assembly contains multiple modules

C Language & |! What are

& Is the address fetch operator used to extract the address of a variable.
For example, if you define a variable, the system will allocate a space in the memory during compilation.
The location of the space in the memory is its address. & Extract its address.
E. g int a; assign an address to it during compilation, for example, 2000; & a is 2000.
If an integer pointer Variable p, p = & a; is defined, the address 2000 of a is assigned to p. P = 2000 after running.
Another example is scanf ("% d", & a). When you enter 3, it first knows the address of a according to & a, and finds the space of a in the memory by the address, write 3 to this space.
* Is a pointer operator, which is opposite to &. It extracts the value of a Variable Based on the address of the variable.
For example, * the value of a is 3 of variable.
The following is a summary of the pointer used in the definition and description.
Int * p; defines a pointer to integer data.
Int * p [n]; defines the pointer array p, which consists of n pointer elements pointing to integer data.
Int (* p) [n]; p is the pointer variable pointing to a one-dimensional array containing n elements.
Int * p (); p is the function that returns a pointer pointing to integer data.
Int (* p) (); p is the pointer to the function. This function returns an integer value.
Int ** p; p is a pointer variable that points to an integer Data Pointer variable.
If you want to learn more about the system, you can refer to tan haoqiang's c Programming (the third edition), which is easy to understand. Is a good C language learning material.
