HttpParsingException


                public class HttpParsingException : HttpRequestException

Summary

Represents errors that occur during HTTP header parsing. This exception is thrown when the .NET HTTP client encounters malformed or invalid HTTP headers during a request or response.

Namespace: System.Net.Http.Headers

Inheritance

object
Exception
System.Net.Http.HttpRequestException
System.Net.Http.Headers.HttpParsingException

Implements

System.Runtime.Serialization.ISerializable

Exceptions

The base class, HttpRequestException, can also throw exceptions related to network connectivity or general HTTP request issues.

Properties

Headers: Gets the collection of HTTP headers that caused the parsing error.
Message: Gets a message that describes the current exception. (Inherited from Exception)
InnerException: Gets the exception that is the cause of the current exception. (Inherited from Exception)
StackTrace: Gets a string representation of the immediate frames of the call stack. (Inherited from Exception)

Remarks

This exception is primarily used internally by the .NET HTTP client implementation. Developers typically don't throw this exception directly but might catch it if they are performing advanced network protocol handling or debugging.

It signifies a violation of the HTTP/1.1 or HTTP/2 protocol specifications regarding the structure or content of headers.

Usage

While direct instantiation and throwing are uncommon, you might encounter this exception when dealing with custom HTTP header processing or when debugging network-related issues.

                // Example of catching the exception (demonstrative, as direct throwing is rare)
                try
                {
                    // Code that might trigger HttpParsingException
                    // For instance, sending a request with severely malformed headers
                    // (This is highly unlikely in standard usage)
                }
                catch (System.Net.Http.Headers.HttpParsingException ex)
                {
                    Console.WriteLine($"HTTP Parsing Error: {ex.Message}");
                    if (ex.Headers != null)
                    {
                        Console.WriteLine("Problematic Headers:");
                        foreach (var header in ex.Headers)
                        {
                            Console.WriteLine($"- {header.Key}: {string.Join(", ", header.Value)}");
                        }
                    }
                }
                catch (System.Net.Http.HttpRequestException ex)
                {
                    Console.WriteLine($"HTTP Request Error: {ex.Message}");
                }
