Here's an example of a method with parameters in C#:
public void CalculateSum(int num1, int num2)
{
int sum = num1 + num2;
Console.WriteLine("Sum: " + sum);
}
In this method, num1 and num2 are parameters that specify the data types (int in this case) and order of the values that the CalculateSum method expects to receive.
Arguments :
Arguments, on the other hand, are the actual values that are passed to a method when it is called. These values are assigned to the parameters defined in the method signature. When you invoke a method, you provide arguments that match the data types and order of the parameters in the method declaration.
Here's an example of calling the CalculateSum method with arguments:
CalculateSum(5, 3);
In this call, 5 and 3 are the arguments passed to the CalculateSum method. These values are assigned to num1 and num2 respectively within the method.
Key Differences :
- Parameters are defined in the method signature, while arguments are the actual values passed to the method.
- Parameters act as placeholders for data types and order, while arguments are the concrete values supplied to the method.
- Parameters are used to define the method's input requirements, while arguments fulfill those requirements during method invocation.
