C# Implicit/Explicit Type Conversion

Question

I have a simple scenario that may or may not be possible. I have a class that contains an integer, for this purpose I\'ll make it as simple as possible:

pub         


        

Answer 1

Implicit type conversion: Implicit type conversion takes place between smaller to larger integral types but not vice-versa or between derived class and base class. Conversion takes place in type safe manner by C# and no data loss takes place. For example,

int a = 10;
long b = a;
float f = a;

Explicit type conversion: Explicit type conversion done by using built-in C# functions. Data may be lost while explicit type conversion, means if we convert double to int then precision may be lost. Explicit type conversion require casting. To do a casting, need to specify the type that you are casting to in front of the value or variable to be converted.

For example,

double d = 10.20;
int a = (int)d;
//Output: 10

To understand in details follow C# Basics - C# Type Conversion

Answer 2

Implicit conversion

// Implicit conversion. num long can
// hold any value an int can hold, and more!
int num = 2147483647;
long bigNum = num;

Explicit Conversion

class Test
{
    static void Main()
    {
        double x = 1234.7;
        int a;
        // Cast double to int.
        a = (int)x;
        System.Console.WriteLine(a);
    }
}

Hope this may help you.

Answer 3

Try something like this

    public static implicit operator int(Number num)
    {
        return num.Value;
    }

Answer 4

class Number
{  
    public static implicit operator int(Number n)
    {
       return n.Value;
    }
}
