Public Methods

Method Description
ConcatenateRequestElements ( string method, string url, WebParameterCollection parameters ) : string

Creates a request elements concatentation value to send with a request. This is also known as the signature base.
ConstructRequestUrl ( Uri url ) : string

Creates a request URL suitable for making OAuth requests. Resulting URLs must exclude port 80 or port 443 when accompanied by HTTP and HTTPS, respectively. Resulting URLs must be lower case.
GetNonce ( ) : string

Generates a random 16-byte lowercase alphanumeric string.
GetSignature ( OAuthSignatureMethod signatureMethod, OAuthSignatureTreatment signatureTreatment, string signatureBase, string consumerSecret ) : string

Creates a signature value given a signature base and the consumer secret. This method is used when the token secret is currently unknown.
GetSignature ( OAuthSignatureMethod signatureMethod, OAuthSignatureTreatment signatureTreatment, string signatureBase, string consumerSecret, string tokenSecret ) : string

Creates a signature value given a signature base and the consumer secret and a known token secret.
GetSignature ( OAuthSignatureMethod signatureMethod, string signatureBase, string consumerSecret ) : string

Creates a signature value given a signature base and the consumer secret. This method is used when the token secret is currently unknown.
GetSignature ( OAuthSignatureMethod signatureMethod, string signatureBase, string consumerSecret, string tokenSecret ) : string

Creates a signature value given a signature base and the consumer secret and a known token secret.
GetTimestamp ( ) : string

Generates a timestamp based on the current elapsed seconds since '01/01/1970 0000 GMT"
GetTimestamp ( System.DateTime dateTime ) : string

Generates a timestamp based on the elapsed seconds of a given time since '01/01/1970 0000 GMT"
NormalizeRequestParameters ( WebParameterCollection parameters ) : string

Sorts a collection of key-value pairs by name, and then value if equal, concatenating them into a single string. This string should be encoded prior to, or after normalization is run.
SortParametersExcludingSignature ( WebParameterCollection parameters ) : WebParameterCollection

Sorts a WebParameterCollection by name, and then value if equal.
UrlEncodeRelaxed ( string value ) : string

URL encodes a string based on section 5.1 of the OAuth spec. Namely, percent encoding with [RFC3986], avoiding unreserved characters, upper-casing hexadecimal characters, and UTF-8 encoding for text value pairs.
UrlEncodeStrict ( string value ) : string

URL encodes a string based on section 5.1 of the OAuth spec. Namely, percent encoding with [RFC3986], avoiding unreserved characters, upper-casing hexadecimal characters, and UTF-8 encoding for text value pairs.
