Sometimes it's handy to have access to your language to do quick things without starting Visual Studio and creating a new console app.

Is there some开发者_StackOverflow中文版thing like Python's interactive mode or groovy shell, except for C#?

Update for 2022

After installing Visual Studio 2022, add the following to your PATH environment variable.

C:\Program Files (x86)\Microsoft Visual Studio\Shared\Packages\Microsoft.Net.Compilers.2.6.1\tools

Then open your terminal (CMD, PowerShell, Windows Terminal) and type csi to run C Sharp Interactive.

You'll get something like this:

PS C:\> csi
Microsoft (R) Visual C# Interactive Compiler version 2.6.1.62414
Copyright (C) Microsoft Corporation. All rights reserved.

Type "#help" for more information.
> var list = new List<int>{ 1, 2, 3, 4 };
> list // You don't need to call Console.WriteLine() to see values
List<int>(4) { 1, 2, 3, 4 }
> // You can keep adding lines as needed

Previous Answer

With the Visual Studio 2015 Update 1 there now is a C# Interactive tool window built into Visual Studio.

The new tool window is invoked by going to View → Other Windows → C# Interactive.

For Visual Studio 2010 to 2013 you can use the Roslyn CTP to get a similar tool window in Visual Studio.

Have a look at CsharpRepl (part of the Mono project). Never used it myself, I hasten to add.

For LINQ stuff, you should also look at LINQPad.

---

There are several.

• CsharpRepl
• CSI: A Simple C# Interpreter
• SnippetCompiler
• LINQPad

---

Like others noted, Mono's CSharpRepl is probably the right answer. However, if you're not fixed to C#, then PowerShell is a pretty nice environment of playing around with .NET. I frequently use it to test regular expressions, format strings, etc. All the kinds of stuff you have ConsoleProject163 lying around for :)

---

In addition to the other good answers here (+1), there is also CSI and the immediate window in Visual Studio.

---

Here is a Mono CsharpRepl which is what you are looking for.

This documents the features available in the C# interactive shell that is part of Mono's C# compiler. An interactive shell is usually referred to as a read eval print loop or repl. The C# interactive shell is built on top of the Mono.CSharp (http:/monodoc/N:Mono.CSharp) library, a library that provides a C# compiler service that can be used to evaluate expressions and statements on-the-fly.

---

There is ScriptCS which uses the Roslyn CTP nuget package.

---

I think CShell would be a nice contribution to answers given here. It provides code completion enabled REPL command window as well as a lightweight workspace management tools to include some scratch files and library references.

---

With Roslyn CTP there now is a full C# interactive window from Microsoft direct in Visual Studio!! Works great! So far runs all my libraries. After install: Invoking View -> Other Windows -> C# Interactive from the menu.

---

I use ideone.com sometimes, but LINQPad is a good choice if an install is acceptable.

---

You can use this developed by Miguel De Icaza, is shipped with mono and have code completion

If you are looking for a simple web based environment to crank out some C# code try coderpad.io Not sure if you can add libraries n' all but its a quick and simple solution if you are just interested in testing out several commands
