Parameters

Type	Name	Description
System.Int32	retryCount	The maximum number of retry attempts.
TimeSpan	minBackoff	The minimum back-off time
TimeSpan	maxBackoff	The maximum back-off time.
TimeSpan	deltaBackoff	The value that will be used for calculating a random delta in the exponential delay between retries.

ExponentialBackoff(String, Int32, TimeSpan, TimeSpan, TimeSpan)

Initializes a new instance of the ExponentialBackoff class.

Declaration

public ExponentialBackoff(string name, int retryCount, TimeSpan minBackoff, TimeSpan maxBackoff, TimeSpan deltaBackoff)

Parameters

Type	Name	Description
System.String	name	The name of the retry strategy.
System.Int32	retryCount	The maximum number of retry attempts.
TimeSpan	minBackoff	The minimum back-off time
TimeSpan	maxBackoff	The maximum back-off time.
TimeSpan	deltaBackoff	The value that will be used for calculating a random delta in the exponential delay between retries.

ExponentialBackoff(String, Int32, TimeSpan, TimeSpan, TimeSpan, Boolean)

Initializes a new instance of the ExponentialBackoff class.

Declaration

public ExponentialBackoff(string name, int retryCount, TimeSpan minBackoff, TimeSpan maxBackoff, TimeSpan deltaBackoff, bool firstFastRetry)

Parameters

Type	Name	Description
System.String	name	The name of the retry strategy.
System.Int32	retryCount	The maximum number of retry attempts.
TimeSpan	minBackoff	The minimum back-off time
TimeSpan	maxBackoff	The maximum back-off time.
TimeSpan	deltaBackoff	The value that will be used for calculating a random delta in the exponential delay between retries.
System.Boolean	firstFastRetry	Indicates whether or not the very first retry attempt will be made immediately whereas the subsequent retries will remain subject to retry interval.

Methods

GetShouldRetry()

Returns the corresponding ShouldRetry delegate.

Declaration
