HttpParsingException

public sealed class HttpParsingException : FormatException

Overview

Represents an error that occurs when parsing an HTTP header. This exception is thrown when the content of an HTTP header cannot be parsed into a valid .NET type according to RFC specifications.

When to Catch

Catch HttpParsingException when you are performing operations that involve parsing or validating HTTP headers, such as:

  • Deserializing HTTP messages.
  • Processing custom HTTP headers.
  • Validating incoming or outgoing HTTP traffic.

Exceptions thrown by this class

This class does not throw exceptions by itself.

Remarks

The HttpParsingException provides details about the invalid header content, including the invalid value and the position within the header where the parsing error occurred. This information can be useful for debugging and for providing more specific error messages to users or other systems.

Note: It is generally recommended to catch more specific exceptions like ArgumentException or FormatException if your operation could lead to those, but HttpParsingException provides a more context-specific error for HTTP header parsing failures.
