Remarks

The HttpProductInfoHeaderValue class represents product information used in the User-Agent HTTP header on an HTTP request.

The User-Agent header contains information about the user agent originating the request. The User-Agent header can contain multiple product tokens, each followed by optional comments which together identify the user agent and any sub-products. By convention, the product identifiers are listed in decreasing order of their significance for identifying the user agent software. Each product identifier consists of a name and optional version.

Each instance of the HttpProductInfoHeaderValue contains either a value for the Product or Comment property, but not both simultaneously.

The UserAgent property on the HttpRequestHeaderCollection returns an HttpProductInfoHeaderValueCollection that contains HttpProductInfoHeaderValue objects.

Constructors

HttpProductInfoHeaderValue(String, String)	Initializes a new instance of the HttpProductInfoHeaderValue class with a product name and version.
HttpProductInfoHeaderValue(String)	Initializes a new instance of the HttpProductInfoHeaderValue class with a product comment.

Properties

Comment	Gets the product comment from the HttpProductInfoHeaderValue used in the User-Agent HTTP header.
Product	Gets the product from the HttpProductInfoHeaderValue used in the User-Agent HTTP header.

Methods

Parse(String)	Converts a string to an HttpProductInfoHeaderValue instance.
ToString()	Returns a string that represents the current HttpProductInfoHeaderValue object.
TryParse(String, HttpProductInfoHeaderValue)	Determines whether a string is valid HttpProductInfoHeaderValue information.
