Simplify name (IDE0001)

  • Статия
Property Value
Rule ID IDE0001
Title Simplify name
Category Style
Subcategory Unnecessary code rules (expression-level preferences)
Applicable languages C# and Visual Basic

Overview

This rule concerns the use of simplified type names in declarations and executable code, when possible. You can remove unnecessary name qualification to simplify code and improve readability.

Note

Even if you enable code style rules on build, this rule is not enabled. It only surfaces in the Visual Studio editor.

Options

This rule has no associated code-style options.

Example

using System.IO;
class C
{
    // IDE0001: 'System.IO.FileInfo' can be simplified to 'FileInfo'
    System.IO.FileInfo file;

    // Fixed code
    FileInfo file;
}

Imports System.IO
Class C
    ' IDE0001: 'System.IO.FileInfo' can be simplified to 'FileInfo'
    Private file As System.IO.FileInfo

    ' Fixed code
    Private file As FileInfo
End Class

Suppress a warning

If you want to suppress only a single violation, add preprocessor directives to your source file to disable and then re-enable the rule.

#pragma warning disable IDE0001
// The code that's violating the rule is on this line.
#pragma warning restore IDE0001

To disable the rule for a file, folder, or project, set its severity to none in the configuration file.

[*.{cs,vb}]
dotnet_diagnostic.IDE0001.severity = none

To disable all of the code-style rules, set the severity for the category Style to none in the configuration file.

[*.{cs,vb}]
dotnet_analyzer_diagnostic.category-Style.severity = none
