db.StringSet("key", 11021);
int i = (int)db.StringGet("key");
Or using StackExchange.Redis.Extensions:
db.Add("key", 11021);
int i = db.Get<int>("key");
Verbatim strings can be combined with the new String interpolation features found in C#6.
Console.WriteLine($@"Testing \n 1 2 {5 - 2}
New line");
Output:
Testing \n 1 2 3
New line

String interpolation allows the developer to combine variables and text to form a string.
Basic Example
Two int variables are created: foo and bar.
int foo = 34;
int bar = 42;
string resultString = $"The foo is {foo}, and the bar is {bar}.";
Console.WriteLine(resultString);

An interface is used to enforce the presence of a method in any class that 'implements' it. The interface is defined with the keyword interface and a class can 'implement' it by adding : InterfaceName after the class name. A class can implement multiple interfaces by separating each interface with ...

Visual Studio helps manage user and application settings. Using this approach has these benefits over using the appSettings section of the configuration file.
Settings can be made strongly typed. Any type which can be serialized can be used for a settings value.
Application settings can be...
Type constraints are able to force a type parameter to implement a certain interface or class.
interface IType;
interface IAnotherType;
// T must be a subtype of IType
interface IGeneric<T>
where T : IType
{
}
// T must be a subtype of IType
class Generic<T>
where T...
It is possible to specify whether or not the type argument should be a reference type or a value type by using the respective constraints class or struct. If these constraints are used, they must be defined before all other constraints (for example a parent type or new()) can be listed.
// TRef mus...
By using the new() constraint, it is possible to enforce type parameters to define an empty (default) constructor.

{
public Foo () { }
}
class Bar
{
public Bar (string s) { ... }
}
class Factory<T>
where T : new()
{

Explicit interface implementation is necessary when you implement multiple interfaces who define a common method, but different implementations are required depending on which interface is being used to call the method (note that you don't need explicit implementations if multiple interfaces share t...
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...
