C#按值调用

在C#中,值类型参数是将原始值的副本传递给函数而不是引用的函数。它不会修改原始值。传递值的更改不会更改实际值。在以下示例中,我们在函数调用期间获得了传递值。

C#按值调用示例

using System;
namespace CallByValue
{
    class Program
    {
        // User defined function
        public void Show(int val)
        {
             val *= val; // Manipulating value
            Console.WriteLine("Value inside the show function "+val);
            // No return statement
        }
        // Main function, execution entry point of the program
        static void Main(string[] args)
        {
            int val = 50;
            Program program = new Program(); // Creating Object
            Console.WriteLine("Value before calling the function "+val);
            program.Show(val); // Calling Function by passing value          
            Console.WriteLine("Value after calling the function " + val);
        }
    }
}

输出:

Value before calling the function 50
Value inside the show function 2500
Value after calling the function 50
