问题 What state is saved between rerunning queries in Linqpad? I presumed none, so if you run a script twice it will have the same results both time. However run the C# Program below twice in the same Linqpad tab. You'll find the first it prints an empty list, the second time a list with the message 'hey'. What's going on? System.ComponentModel.TypeDescriptor.GetAttributes(typeof(String)).OfType<ObsoleteAttribute>().Dump(); System.ComponentModel.TypeDescriptor.AddAttributes(typeof(String),new

问题 In order to get results in a random order from a Sql query I generally sort by new Guids. I have done this before with Entity-Framework, however for some reason its not working now. For example (using the adventureworks2008r2 database) i run the following query in LinqPad: (from t in Employees orderby Guid.NewGuid() select new {t.Person.FirstName,t.Person.LastName,t.JobTitle}) This generates the following SQL: SELECT [t1].[FirstName], [t1].[LastName], [t0].[JobTitle] FROM [HumanResources].

问题 In LinqPad, trying to call .Dump() on a Newtonsoft JSON.Net JObject yields an exception: RuntimeBinderException: 'Newtonsoft.Json.Linq.JObject' does not contain a definition for 'Dump'. This works for almost everything else in LinqPad. I'd like to figure out a method that will Dump out a Newtonsoft JObject , just like other objects, showing property names, values, etc. I've already figured out how to get it to dump the JSON string, but I'd like to see an object get output rather than just a

问题 This question already has answers here : How do I use the LINQPad Dump() extension method in Visual Studio? [closed] (4 answers) Closed 5 years ago . I work with a lot of Linq queries in my code, and I'm looking for a library that provides a formatted Dump() function similar to what LinqPad offers. LinqPad's Dump() extension method is really quite nice, because it handles nested collections very well. Ideally, it would print out pretty tables in plain text, but I'd be ok with spitting out

问题 I'm trying to implement some retry logic base on this post (but with tasks) Cleanest way to write retry logic? The idea for the retry logic is to then to implement a second task that triggers the cancelation after a give amount of time void Main() { RetryAction(() => Sleep(), 500); } public static void RetryAction(Action action, int timeout) { var cancelSource = new CancellationTokenSource(); cancelSource.CancelAfter(timeout); Task.Run(() => action(), cancelSource.Token); } public static void

问题 I have two XML files with the same schema/structure but with different data. I am trying to use Linqpad (Linq to XML) to find the differences between the two files. Here is my code... XElement FILE1 = XElement.Load (@"..\FILE1.XML"); XElement FILE2 = XElement.Load (@"..\FILE2.XML"); var orders = from file1 in FILE1.Descendants("Players").Elements("Player") select new { name=new { firstName=file1.Element("FirstName"), lastName=file1.Element("LastName") } }; var orders2 = from file2 in FILE2
