Stack

این ساختمان داده، داخل Memory پیاده سازی شده است و تعدادی از متغیرهایی را که ما داخل کد ایجاد میکنیم، در این نوع ساختمان داده از Memory نگهداری میشوند.

شرط قرار گرفتن مقدار یک متغیر داخل Stack این است که متغیر از نوع Value Type باشد. در زبان #C، بطور کلی Struct و Enum‌ها Value Type هستند و بصورت پیشفرض داخل Stack قرار میگیرند. تمامی ValueType‌ها در #C، بطور implicit از System.ValueType ارث بری میکنند.

Type‌های زیر، Value Type‌های پیشفرض تعریف شده‌ی در زبان #C هستند که به آن‌ها Simple Type نیز گفته میشوند:

Heap

public static void SayHi()
{
    string name = "Moien";
}

.method private hidebysig static void SayHi() cil managed
{
  .locals init (string V_0)

  IL_0001:  ldstr      "Moien" // Stack is: [memory-address of string in heap]
  IL_0006:  stloc.0
  
  IL_0007:  ret
}

Boxing and Unboxing

public static void Boxing()
{
    const int number = 5;
    
    object boxedNumber = number;          // implicit boxing using implicit cast
    object boxedNumber = (object)number;  // explicit boxing using direct cast
}

.method public hidebysig static void Boxing() cil managed
{
  .locals init (object V_0)
  
  IL_0001:  ldc.i4.5                                // Stack is: [5]
  IL_0002:  box        [System.Runtime]System.Int32 // Stack is: [memory-address of 5 in heap]
  
  IL_0007:  stloc.0
  IL_0008:  ret
}

public static void Unboxing()
{
    object boxedNumber = 5;
    
    int number = (int)boxedNumber;
}

.method public hidebysig static void Unboxing() cil managed
{
  .locals init (object V_0, int32 V_1)
  
  IL_0001:  ldc.i4.5                                  // Stack is: [5]
  IL_0002:  box        [System.Runtime]System.Int32   // Stack is: [memory-address of 5 in heap]
  IL_0007:  stloc.0                                   // Stack is: []
                                                      
  IL_0008:  ldloc.0                                   // Stack is: [memory-address of 5 in heap]
  IL_0009:  unbox.any  [System.Runtime]System.Int32   // Stack is: [5]
  IL_000e:  stloc.1                                   // Stack is: []
  
  IL_000f:  ret

This year's State of JavaScript survey is now open, and filling it out only takes slightly longer than listening to that song in its entirety (not that anybody deserves that fate). 

When you go to https://vscode.dev, you'll be presented with a lightweight version of VS Code running fully in the browser. Open a folder on your local machine and start coding.

No install required. 

On April 18th, during our regular security audit of nonSql databases with BinaryEdge search engine, I have discovered an open and publicly available MongoDB instance which contained astonishingly sensitive information on Iranian drivers.
