what does static mean in csharp
Code Example - what does static mean in csharp
In C#, static means something which cannot be instantiated. You cannot create an object of a static class and cannot access static members using an object. C# classes, variables, methods, properties, operators, events, and constructors can be defined as static using the static modifier keyword.
csharp public static string
public static string saytest = "test";
private static void Main()
{
Console.WriteLine(saytest);
}
csharp static
public class MyClass
{
//Instance variable to be automatically set to five
public int instanceVar = 5;
//Variable belonging to the type/class
public static int typeVar = 10;
}
public class MainClass
{
void Main()
{
//Field is accesible as it is a variable belonging to the type as a whole
Console.WriteLine(MyClass.typeVar);
//The following would throw an error, because the type isn't an instance
//Console.WriteLine(MyClass.instanceVar)
//Create an instance of the defined class
MyClass instance = new MyClass();
//Writes 5, because we told it to be set to 5 upon creation of the object
Console.WriteLine(instance.instanceVar);
instance.instanceVar += 22; //Add 22 to the instance's variable
NyClass second = new MyClass(); //Create a second instance, named 'second'
Console.WriteLine(instance.instanceVar);//27, unless i did my math wrong :/
//The second instance has it's own variable separate from the first
Console.WriteLine(second.instanceVar);//5
}
}
static property in csharp
using System;
class Example
{
static int _count;
public static int Count
{
get
{
// Side effect of this property.
_count++;
return _count;
}
}
}
class Program
{
static void Main()
{
Console.WriteLine(Example.Count);
Console.WriteLine(Example.Count);
Console.WriteLine(Example.Count);
}
