Provides functionality to manage the lifetime of HTTP-related objects, ensuring proper disposal and resource management.

Summary

The HttpLifetimeProvider class is a utility designed to simplify the management of the lifecycle of HTTP clients and their associated resources. It helps in scenarios where multiple HTTP requests might be made, and it's crucial to ensure that underlying connections and other resources are handled correctly to avoid leaks or performance issues.

Remarks

This class is typically used internally by the .NET framework to manage the lifetime of HttpClient instances, particularly in scenarios involving connection pooling and keep-alive mechanisms. Developers might interact with it indirectly through the behavior of HttpClient itself, or in advanced scenarios where custom resource management for HTTP operations is required.

Proper management of HTTP lifetimes is essential for building robust and scalable network applications. Issues like unbounded resource consumption or premature disposal of connections can lead to errors and degraded performance.

Members

Constructors

HttpLifetimeProvider()

public HttpLifetimeProvider()

Initializes a new instance of the HttpLifetimeProvider class.

Fields

Disposed

protected bool Disposed

Indicates whether the object has been disposed.

This protected field is a common pattern for tracking the disposal state of an object implementing IDisposable.

Properties

IsDisposed

public bool IsDisposed { get; }

Gets a value indicating whether the object has been disposed.

A public accessor to check the disposal status of the HttpLifetimeProvider instance.

Methods

Dispose()

public void Dispose()

Releases the unmanaged resources used by the HttpLifetimeProvider and optionally releases the managed resources.

This method is part of the IDisposable pattern and should be called when the object is no longer needed to free up system resources.

DisposeAsync()

public ValueTask DisposeAsync()

Asynchronously releases the unmanaged resources used by the HttpLifetimeProvider and optionally releases the managed resources.

This asynchronous version of Dispose is useful for scenarios where disposal operations might involve I/O or other asynchronous operations.

Example

Basic Usage (Illustrative)

While HttpLifetimeProvider is often used internally, a conceptual example of managing an HttpClient's lifetime might look like this:

// Note: This is a conceptual illustration. // Direct instantiation and management of HttpLifetimeProvider // is typically handled by higher-level .NET constructs. // using var httpClient = new HttpClient(); // // HttpClient itself manages its lifetime and underlying resources. // // The HttpLifetimeProvider is part of this internal management. // Console.WriteLine("HttpClient operations..."); // // When httpClient goes out of scope, its Dispose method is called. // // This implicitly involves HttpLifetimeProvider's logic. // Console.WriteLine("HttpClient disposed."); // // Example demonstrating the need for proper disposal: // var lifetimeProvider = new HttpLifetimeProvider(); // try // { // // Perform HTTP operations here... // Console.WriteLine("Performing HTTP operations..."); // } // finally // { // lifetimeProvider.Dispose(); // Or DisposeAsync() // }
