46: EventListener truncates strings with embedded nulls

Scope

Edge

Version Introduced

4.5.1

Source Analyzer Status

Available

Change Description

EventListener truncates strings with embedded nulls. Null characters are not supported by the EventSource class. The change only affects apps that use EventListener to read EventSource data in process and that use null characters as delimiters.

• Quirked
• Build-time break

Recommended Action

EventSource data should be updated, if possible, to not use embedded null characters.

Affected APIs

• M:System.Diagnostics.Tracing.EventListener.#ctor
• M:System.Diagnostics.Tracing.EventListener.EnableEvents(System.Diagnostics.Tracing.EventSource,System.Diagnostics.Tracing.EventLevel)
• M:System.Diagnostics.Tracing.EventListener.EnableEvents(System.Diagnostics.Tracing.EventSource,System.Diagnostics.Tracing.EventLevel,System.Diagnostics.Tracing.EventKeywords)
• M:System.Diagnostics.Tracing.EventListener.EnableEvents(System.Diagnostics.Tracing.EventSource,System.Diagnostics.Tracing.EventLevel,System.Diagnostics.Tracing.EventKeywords,System.Collections.Generic.IDictionary{System.String,System.String})
