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
