Remove code redundancies

On the Code Inspection | Inspection Severity page of ReSharper options (Alt+R, O), in the Redundancies in Code categories for most languages, ReSharper lists over 50 redundancies that have associated code inspections. Some of them require special attention, and you cannot process them in the batch mode. That leaves Code Cleanup with about 30 redundancies that it is able to remove automatically whenever you select Remove code redundancies in your cleanup profile.

Specifically, code cleanup:

• Removes:

  • Redundant empty constructors.

  • Explicit integer type specifiers in enumerations.

  • true specifiers in for statements.

  • Redundant type casts.

  • Redundant parentheses from attributes without arguments.

  • Explicit calls to base class constructors without arguments.

  • Redundant boolean comparisons.

  • Redundant braces from collection initializers with a single expression.

  • Redundant explicit delegate creation expressions.

  • Empty argument lists from object/collection initializers.

  • Redundant new keywords.

  • Redundant partial modifiers on type declarations where a type has a single part.

  • Redundant unsafe contexts and statements.

  • Redundant object.ToString() calls (for example, in a concatenation with a string or as an argument of a string.Format() call).

  • Redundant string.ToCharArray() calls.

  • Redundant specifications of argument types.

  • Signatures in anonymous methods where its parameters are not used in the method body.

  • Non-referenced labels.

  • Redundant field initializers.

  • Redundant explicit names in anonymous type properties.

  • Redundant nullable types where value type is implicitly convertible to nullable.

• Converts:

  • Nullable types to short form Nullable<T> to T?.

  • Static method invocations to extension method calls where extension methods are invoked as static methods.

  • To implicitly typed array creation expressions when array type can be inferred from initializer.

• Fixes:

  • Occurrences where static members of a type are accessed via derived members of the type.

Use auto-property, if possible

Replaces simple properties and corresponding backing fields with auto-properties. For more information, see Use auto-properties.

Make field read-only, if possible

Adds the 'readonly' keyword to fields that are assigned in the declaration or in a constructor and only have read usages. For more information, see Make fields readonly.

Make auto-property get-only, if possible

Removes the redundant set accessor on auto-properties that are initialized from the constructor/initializer and have no write usages. Note that this task only works for C# 6.0.

By default, ReSharper automatically detects C# version based on the associated compiler. However, you can specify the target C# version explicitly for a project — right-click the project in the Solution Explorer, choose Edit project item properties from the context menu and use the C# Language Level selector.

To set the C# version for all projects in your solution, specify it in a Directory.Build.props file in your solution directory as described here.

Arrange qualifiers

Applies the rules for qualifying type members. The rules are configurable on the Code Editing | C# | Syntax Style page of ReSharper options (Alt+R, O). For more information, see Code Syntax Style: Optional Member Qualifiers.

Fix built-in type references

Applies the rule for built-in type names (C# keyword or CLR type name). The rule is configurable on the Code Editing | C# | Syntax Style page of ReSharper options (Alt+R, O). For more information, see Code Syntax Style: Built-In Type References.

Usings

Includes the following configurable options:

Optimize 'using' directives

Removes unused namespace import directives

by implementing the rules that you can configure on the Code Editing | C# | Namespace Imports and Code Editing | C# | Syntax Style options pages and sorts the namespace import directives: all System.* namespaces go first, sorted alphabetically by the second word after the dot; all other namespaces go next, in alphabetical order.. For more information, see Code Syntax Style: Namespace Imports.

Embrace 'using' directives in region

If this checkbox is selected, a new region for wrapping all namespace import directives is created during cleanup.

Region name

Allows specifying a name for the region wrapping namespace import directives.

Shorten qualified references

Replaces fully qualified names with short names when possible by importing namespaces, implementing settings configured on the Code Editing | C# | Syntax Style page of ReSharper options (Alt+R, O).

Reformat code

Reformats your code according to the preferences that you can configure on the Code Editing | C# | Formatting Style page of ReSharper options (Alt+R, O). For more information, see Manage and apply formatting rules.

Removes definitions if they are redundant in the context

Remove forbidden attributes

Removes attributes, such as name, span if they are forbidden in the context

Reformat code

Reformats your code according to the preferences that you can configure on the Code Editing | XML | Formatting Style page of ReSharper options (Alt+R, O). For more information, see Manage and apply formatting rules.

The selected fixes will be applied even if the corresponding inspections are turned off on the Code Inspection | Inspection Severity page of ReSharper options (Alt+R, O). Be careful when enabling too many checks at once — code cleanup runs Clang-Tidy only once for a given file, so if multiple fixes touch the same block of code, the changes might conflict with each other.

For more information, see Quotes style.

Correct 'var' to 'let'/'const' where possible

let and const are supported in the following cases:

• In JavaScript code, if the target JavaScript language level is ECMAScript 6 (you can choose it on the Code Editing | JavaScript | Inspections page of ReSharper options (Alt+R, O))

• In TypeScript 1.4, if the target ECMAScript 6 is selected in the project properties.

• In TypeScript 1.5 or later.

Move let/const to most possible inner scopes

Moves variables defined outside of a function/compound statement, and so on closer to their usages if there are no other usages in outer scopes.

Convert string concatenations to template strings

const str1 = "Hello, ";
const str2 = `Test: ${str1} World1`;

Reformat code

var bar = <string> foo;

with

var bar = foo as string;

which is a recommended way to avoid ambiguity with JSX syntax.
