问题 I'm trying to save a XML file in DocumentDb in Json format. I have no problem in converting it and saving. All the conversion and saving are working fine. However when I store my Xml file the DocumentDB provides its own file name to the file. Eg; 8756b9b9-41ac-47ca-9f4c-abec60b318be . But I want to save the file with my own custom name Eg; MyXmlFile1 or MyXmlFile2 etc; How do I pass my custom name when saving the file? That is MyXmlFile1 or MyXmlFile2. "jsontoStore" has the content of the

问题 This question already has answers here : How do I create an immutable Class? (6 answers) Closed 6 years ago . I just looked into IReadOnlyList<T> to create readonly list. But I think it is not 100% readonly. I can not add/remove the item from the list but I can still modify the members. Consider this example. class Program { static void Main(string[] args) { List<Test> list = new List<Test>(); list.Add(new Test() { MyProperty = 10 }); list.Add(new Test() { MyProperty = 20 }); IReadOnlyList

Which algorithm do you suggest I use: SHA1 , SHA256 , MD5 , BCrypt , or something else? Also, which way do you suggest to create a password salt? 回答1: BCrypt if you need really strong hash. As far as generating the salt is concerned, you could use the RNGCryptoServiceProvider class. Here's an

问题 I have a set of so called fluent interfaces, so I can use syntax like this: a.With("abc").Do("this").Then("that); Each method returns an object cast to a corresponding interface. At design time I can use Intellisense to easily navigate between API methods. However I can no longer do it if I cast one of the arguments to a dynamic: a.With((dynamic)"abc").Do("this").Then("that); Not only I lose Intellisense at design time, this cast affects runtime execution: all subsequent calls after With

问题 I asked a question to get URL as action input here. Now I have a new problem. The passed URL to action changes from http://example.com to http:/example.com . I want to know why and how can I resolve the problem. P.S: I added this code to resolve but I think there may be another problems in future! the code is: if ((url.Contains(":/")) && !(url.Contains("://"))) { url = url.Replace(":/", "://"); } 回答1: The browser (or server) is replacing a double slash (illegal) with a single one. Try it,

My full server config can be found here:How to make WCF service server-client time difference independent? 回答1: Probably your custom binding is configured in a way that macthed the
