This method will use httpclient post MultipartFormDataContent (multipart/form-data) class properties and pdf file to server. Returns the only element of a sequence, and throws an exception if there is not exactly one element in the sequence. Invokes a transform function on each element of a sequence and returns the minimum Single value. Bypasses a specified number of elements in a sequence and then returns the remaining elements. Sorts the elements of a sequence in descending order by using a specified comparer. I have written an Azure service for creating/updating products by following the above link. Add ('Dept','Technical') To remove the Key-value from the Hashtable, you need to use the Remove (Key) method. Computes the average of a sequence of Int32 values that are obtained by invoking a transform function on each element of the input sequence. What is the best way to show results of a multiple-choice quiz where multiple options may be right? Stack Overflow for Teams is moving to its own domain! By voting up you can indicate which examples are most useful and appropriate. When making some changes to our API recently I realized we needed a way to correlate the files we uploaded with the MediaUploadResult objects sent back in the response. Projects each element of a sequence to an IEnumerable, and flattens the resulting sequences into one sequence.
