In-depth discussion of const, readonly keywords in C #

First of all, these interviews will often be asked by the interviewer, but you answer to the interviewer satisfaction? Of course, if you know these principles, you may not

Afraid of. Since we're talking about the principle, we'll start with MSDN.

A: A few places worth scrutiny

1. Let's take a look at MSDN above on how const is said, we will see. Cannot be modified, compile the constant amount of these critical information.

Why Q:const cannot be modified.

A: This is very simple, and many textbooks say that when the compiler compiles, the values of the constants are stored in the assembly's metadata, and we do an example

Take a look at it.

①: Create a new projecta.

The code is as follows:

ProjectA

public class TestClass

{

public const int Ctrip = Int. MaxValue;

}

Build another mainproject, quoting the next projecta.

The code is as follows:

Using System;

Class Program

{

static void Main (string[] args)

{

Console.WriteLine (Testclass.ctrip);

Console.read ();

}

}
