// Connect to a target server using your ConnectionMultiplexer instance IServer server = conn.GetServer("localhost", 6379); var seq = server.Keys(); IScanningCursor scanningCursor = (IScanningCursor)seq; // Use the cursor in some way...

It is possible to use multiple nested using statements without added multiple levels of nested braces. For example: using (var input = File.OpenRead("input.txt")) { using (var output = File.OpenWrite("output.txt")) { input.CopyTo(output); } // output is ...

emails.Subscribe(email => Console.WriteLine("Email from {0} to {1}", email.From, email.To), cancellationToken);

string helloWorld = "hello world, how is it going?"; string[] parts1 = helloWorld.Split(','); //parts1: ["hello world", " how is it going?"] string[] parts2 = helloWorld.Split(' '); //parts2: ["hello", "world,", "how", "is&qu...

string helloWorld = "Hello World!"; string world = helloWorld.Substring(6); //world = "World!" string hello = helloWorld.Substring(0,5); // hello = "Hello" Substring returns the string up from a given index, or between two indexes (both inclusive).

Use the String.Format() method to replace one or more items in the string with the string representation of a specified object: String.Format("Hello {0} Foo {1}", "World", "Bar") //Hello World Foo Bar

Event declaration: public event EventHandler<EventArgsT> EventName; Event handler declaration: public void HandlerName(object sender, EventArgsT args) { /* Handler logic */ } Subscribing to the event: Dynamically: EventName += HandlerName; Through the Designer: Click the Events...

Events can be of any delegate type, not just EventHandler and EventHandler<T>. For example: //Declaring an event public event Action<Param1Type, Param2Type, ...> EventName; This is used similarly to standard EventHandler events: //Adding a named event handler public void HandlerNa...

Given an IObservable<Offer> of offers from merchants to buy or sell some type of item at a fixed price, we can match pairs of buyers and sellers as follows: var sellers = offers.Where(offer => offer.IsSell).Select(offer => offer.Merchant); var buyers = offers.Where(offer => offer.Is...

This code will subscribe to the emails observable twice: emails.Where(email => email.From == "John").Subscribe(email => Console.WriteLine("A")); emails.Where(email => email.From == "Mary").Subscribe(email => Console.WriteLine("B")); To share a...

The following examples will not compile: string s = "\c"; char c = '\c'; Instead, they will produce the error Unrecognized escape sequence at compile time.

There are several places where you can use String.Format indirectly: The secret is to look for the overload with the signature string format, params object[] args, e.g.: Console.WriteLine(String.Format("{0} - {1}", name, value)); Can be replaced with shorter version: Console.WriteLine...

The nameof operator allows you to get the name of a variable, type or member in string form without hard-coding it as a literal. The operation is evaluated at compile-time, which means that you can rename, using an IDE's rename feature, a referenced identifier and the name string will update with it...
