• public TimeSpan RetryAfter { get; }
  Gets the retry-after interval.

Methods

• public override bool Equals(object obj)
  Determines whether the specified object is equal to the current object.
• public bool Equals(RetryConditionHeaderValue other)
  Determines whether the specified RetryConditionHeaderValue object is equal to the current object.
• public override int GetHashCode()
  Serves as the default hash function.
• public override string ToString()
  Returns a string that represents the current object.
• public static RetryConditionHeaderValue Parse(string input)
  Parses a RetryConditionHeaderValue.
• public static bool TryParse(string input, [out] RetryConditionHeaderValue value)
  Tries to parse a RetryConditionHeaderValue.

Examples

using System;
using System.Net.Http.Headers;

public class Example
{
    public static void Main()
    {
        // Example 1: Using Retry-After date
        var retryDate = new DateTimeOffset(2023, 10, 27, 10, 30, 0, TimeSpan.Zero);
        var retryConditionByDate = new RetryConditionHeaderValue(retryDate);
        Console.WriteLine($"Retry-After: {retryConditionByDate.LastResponseDate}");
        // Output: Retry-After: 2023-10-27 10:30:00 +00:00

        // Example 2: Using Retry-After interval
        var retryInterval = TimeSpan.FromSeconds(60);
        var retryConditionByInterval = new RetryConditionHeaderValue(retryInterval);
        Console.WriteLine($"Retry-After: {retryConditionByInterval.RetryAfter}");
        // Output: Retry-After: 00:01:00

        // Example 3: Parsing a Retry-After header string
        string headerString = "date: Fri, 27 Oct 2023 10:30:00 GMT";
        if (RetryConditionHeaderValue.TryParse(headerString, out var parsedRetryCondition))
        {
            Console.WriteLine($"Parsed Retry-After Date: {parsedRetryCondition.LastResponseDate}");
        }

        headerString = "120"; // Seconds
        if (RetryConditionHeaderValue.TryParse(headerString, out parsedRetryCondition))
        {
            Console.WriteLine($"Parsed Retry-After Interval: {parsedRetryCondition.RetryAfter}");
        }
    }
}
