4.25Setting the Sort Rule for Multipart Form Content Items

Although the need to sort multipart form content items is uncommon, some systems with high security requirements often need to validate the submission order of form fields. The framework provides sorting support for this purpose:

123456

HttpRequestBuilder.Post("https://furion.net")    .SetMultipartContent(multipart =>    {        multipart.AddObject(new { name = "furion", id = 1 });    })    .SetFormItemsSorter(items => items.OrderBy(u => u.Name));

Configure the sort rule for multipart form content items through the .SetFormItemsSorter() method. This method receives the original MultipartFormDataItem collection and returns a sorted enumerable collection. When it is null, no sorting is performed (the original insertion order is used).
