In c#, Passing a Value-Type parameter to a method by value means passing a copy of the variable to the method. So the changes made to the parameter inside the called method will not affect the original data stored in the argument variable.
Following is the example of passing a value type parameter to a method by value in the c# programming language.
If you observe the above example, the variable x is a value type, and it is passed to the Multiplication method. The content of variable x copied to the parameter a and made required modifications in the Multiplication method. Still, the changes made inside of the method do not affect the original value of the variable.
When we execute the above c# program, we will get the result as shown below.
If you observe the above result, the variable value not changed even after we made the modifications in our method.
This is how we can pass parameters to the method by value in the c# programming language based on our requirements.
