Call base method at beginning or end of method in C#?

Call base method at beginning or end of method in C#?

In C#, when overriding a method in a derived class, you can choose whether to call the base method at the beginning or the end of your overridden method. The choice depends on the specific requirements of your scenario and the behavior you want to achieve.

  1. Call Base Method at the Beginning:

    public override void SomeMethod() { // Perform additional logic before calling the base method // Call the base method base.SomeMethod(); }

    By calling the base method at the beginning, you allow the base implementation to execute first, and then you can add or modify the behavior as needed. This approach is useful when you want to extend the functionality of the base method while preserving its original behavior.

  2. Call Base Method at the End:

    public override void SomeMethod() { // Perform additional logic // Call the base method at the end base.SomeMethod(); }

    Calling the base method at the end allows you to execute your custom logic first and then invoke the base implementation. This approach is suitable when you want to override the behavior of the base method entirely or when you want to modify the result or outcome of the base method.

The decision of whether to call the base method at the beginning or the end depends on your specific requirements. Consider the intended behavior, the order of execution you need, and the interaction between the base and derived implementations. Choose the approach that best meets your needs for each particular scenario.

Examples

  1. "C# call base method at the beginning of override method"

    • Code:
      public class BaseClass { public virtual void MyMethod() { // Base class method logic } } public class DerivedClass : BaseClass { public override void MyMethod() { // Call base method at the beginning base.MyMethod(); // Derived class method logic } }
    • Description: This code demonstrates calling the base class method at the beginning of an overridden method in the derived class.

  2. "C# call base method at the end of override method"

    • Code:
      public class BaseClass { public virtual void MyMethod() { // Base class method logic } } public class DerivedClass : BaseClass { public override void MyMethod() { // Derived class method logic // Call base method at the end base.MyMethod(); } }
    • Description: This code illustrates calling the base class method at the end of an overridden method in the derived class.

  3. "C# call base method before custom logic in override"

    • Code:
      public class BaseClass { public virtual void MyMethod() { // Base class method logic } } public class DerivedClass : BaseClass { public override void MyMethod() { // Call base method before custom logic base.MyMethod(); // Derived class custom logic } }
    • Description: This code shows calling the base class method before adding custom logic in an overridden method of the derived class.

  4. "C# call base method after custom logic in override"

    • Code:
      public class BaseClass { public virtual void MyMethod() { // Base class method logic } } public class DerivedClass : BaseClass { public override void MyMethod() { // Derived class custom logic // Call base method after custom logic base.MyMethod(); } }
    • Description: This code exemplifies calling the base class method after adding custom logic in an overridden method of the derived class.

  5. "C# base method call in try-catch block"

    • Code:
      public class BaseClass { public virtual void MyMethod() { // Base class method logic } } public class DerivedClass : BaseClass { public override void MyMethod() { try { // Call base method in try block base.MyMethod(); // Derived class custom logic } catch (Exception ex) { // Handle exception } } }
    • Description: This code demonstrates calling the base class method within a try-catch block in an overridden method of the derived class.

  6. "C# call base method conditionally in override"

    • Code:
      public class BaseClass { public virtual void MyMethod() { // Base class method logic } } public class DerivedClass : BaseClass { public override void MyMethod() { // Some condition if (/* condition */) { // Call base method conditionally base.MyMethod(); } // Derived class custom logic } }
    • Description: This code showcases calling the base class method conditionally in an overridden method of the derived class.

  7. "C# call base method in using statement"

    • Code:
      public class BaseClass { public virtual void MyMethod() { // Base class method logic } } public class DerivedClass : BaseClass { public override void MyMethod() { // Call base method in using statement using (var resource = new SomeDisposableResource()) { base.MyMethod(); // Derived class custom logic } } } public class SomeDisposableResource : IDisposable { public void Dispose() { // Dispose logic } }
    • Description: This code demonstrates calling the base class method within a using statement for a disposable resource in an overridden method of the derived class.

  8. "C# call base method in a loop"

    • Code:
      public class BaseClass { public virtual void MyMethod() { // Base class method logic } } public class DerivedClass : BaseClass { public override void MyMethod() { for (int i = 0; i < 5; i++) { // Call base method in a loop base.MyMethod(); // Derived class custom logic } } }
    • Description: This code shows calling the base class method within a loop in an overridden method of the derived class.

  9. "C# call base method in a parallel task"

    • Code:
      using System.Threading.Tasks; public class BaseClass { public virtual void MyMethod() { // Base class method logic } } public class DerivedClass : BaseClass { public override void MyMethod() { Parallel.For(0, 5, i => { // Call base method in a parallel task base.MyMethod(); // Derived class custom logic }); } }
    • Description: This code demonstrates calling the base class method within a parallel task using Parallel.For in an overridden method of the derived class.

  10. "C# call base method with different parameters in override"

    • Code:
      public class BaseClass { public virtual void MyMethod(int value) { // Base class method logic with parameter } } public class DerivedClass : BaseClass { public override void MyMethod(int value) { // Call base method with different parameters in override base.MyMethod(value); // Derived class custom logic } }
    • Description: This code exemplifies calling the base class method with different parameters in an overridden method of the derived class.
