C # System Learning (Second-class compilation, binary conversion)

Compile:

Machine language 00001 000101

Symbolic ADD SUB for assembly language Machine languages

High-level language C source code--compilation--"machine language (the role of the compiler)

C # Compilation

C # source code--"Microsoft intermediate Language (MSIL) (release software)--" machine language

2 compilations. The second compilation is called Instant compilation (JIT)

Binary conversion

Change the 2,8,16 into a 10-input system, respectively.

Console.WriteLine (Convert.ToInt32 ("110011", 2));
Console.WriteLine (Convert.ToInt32 ("567", 8));
Console.WriteLine (Convert.ToInt32 ("6f", 16));

Convert the 10 binary to the 2,8,16 binary respectively. Note that the string returned is actually

Console.WriteLine (Convert.ToString (89, 2));
Console.WriteLine (Convert.ToString (89, 8));
Console.WriteLine (Convert.ToString (89, 16));
