Can visual studio suggest variable names?

Question

Eclipse can automatically create (or suggest) variable names. For instance if I have a class named MyClass and i want to create an object from it, MyClass myClass = new MyClass(); In Eclipse after class name (MyClass) i hit ctrl+space key and Eclipse automaticly suggests name for the variable (myClass). Is there any similar feature in Visual Studio?

Answer 1

Visual Studio does not do what you're describing, but it is possible to get this functionality through extensions. I know ReSharper does this (and much more), so you might want to give it a try.

Answer 2

There are two free options I see:

1) Free Visual Studio extension .net AutoCode.
Just install it and type in the code:
MyClass i
and press Ctrl + Enter. AutoCode will replace MyClass i with
MyClass myClass = new MyClass();

2) You could write a code snippet and save it with, say newvar.snippet name, to custom snippets folder (usually C:\Users\UserName\Documents\Visual Studio NNNN\Code Snippets\Visual C#\My Code Snippets):

<?xml version="1.0" encoding="utf-8"?>
<CodeSnippets xmlns="http://schemas.microsoft.com/VisualStudio/2005/CodeSnippet">
  <CodeSnippet Format="1.0.0">

      <Shortcut>newvar</Shortcut>
    </Header>
    <Snippet>
      <Imports>
        <Import>
        </Import>
      </Imports>
      <Declarations>
        <Literal Editable="true">
          <ID>type</ID>
          <ToolTip>type</ToolTip>
          <Default>type</Default>
          <Function>
          </Function>
        </Literal>
      </Declarations>
      <Code Language="csharp"><![CDATA[$type$ $type$ = new $type$($end$);]]></Code>
    </Snippet>
  </CodeSnippet>
</CodeSnippets>

When you restart your VS and type in the code
newvar
and then press Tab key twice
VS will insert type type = new type();
with first "type" word highlited. Type in appropriate class name MyClass (autocompletion is enabled) and press Enter key twice. VS will replace code:
MyClass MyClass = new MyClass();
Unfortunatly, variable would get the name of its class (see SO answer and suggestion on visualstudio.uservoice.com). But it's very easy to fix (improper variable case) manually.

Answer 3

Visual Studio does not suggest variable names, but it should complete most other things.

For example, if you do MyClass myClass = it should pop up an IntelliSense box with new MyClass(); in it.

It does have some useful things, however, that can quickly create things for you. For example, if you type class and press TAB twice, it will create a class template, or if you type ctor or mbox it will create a constructor or MessageBox.Show() call, respectively.
