GeneratedRegexAttribute Class (System.Text.RegularExpressions) | Microsoft Learn

Instructs the System.Text.RegularExpressions source generator to generate an implementation of the specified regular expression.

public ref class GeneratedRegexAttribute sealed : Attribute

[System.AttributeUsage(System.AttributeTargets.Method | System.AttributeTargets.Property, AllowMultiple=false, Inherited=false)]
public sealed class GeneratedRegexAttribute : Attribute

[System.AttributeUsage(System.AttributeTargets.Method, AllowMultiple=false, Inherited=false)]
public sealed class GeneratedRegexAttribute : Attribute

[<System.AttributeUsage(System.AttributeTargets.Method | System.AttributeTargets.Property, AllowMultiple=false, Inherited=false)>]
type GeneratedRegexAttribute = class
    inherit Attribute

Attributes

The generator associated with this attribute only supports C#. It only supplies an implementation when applied to partial, parameterless, non-generic methods that are typed to return Regex.

When the Regex supports case-insensitive matches (either by passing IgnoreCase or using the inline `(?i)` switch in the pattern) the regex engines will use an internal casing table to transform the passed in pattern into an equivalent case-sensitive one. For example, given the pattern `abc`, the engines will transform it to the equivalent pattern `[Aa][Bb][Cc]`. The equivalences found in this internal casing table can change over time, for example in the case new characters are added to a new version of Unicode. When using the source generator, this transformation happens at compile time, which means the casing table used to find the equivalences will depend on the target framework at compile time. This differs from the rest of the Regex engines, which perform this transformation at run time, meaning they will always use casing table for the current runtime.
