EventSchemaTraceListener.MaximumFileSize Property

Gets the maximum size of the log file.

Namespace:  System.Diagnostics
Assembly:  System.Core (in System.Core.dll)

public long MaximumFileSize { get; }

Property Value

Type: System.Int64
The maximum file size, in bytes.

The property value is set by the maximumFileSize parameter in the constructor or the maximumFileSize attribute in the configuration file. For performance reasons, you should set the maximum file size to a multiple of 1024 bytes. The MaximumFileSize property value is not an absolute; it is a threshold that can be exceeded up to the size of the last message.

The following table shows the possible and default values for file size that are associated with each trace log retention option. The values marked as N/A indicate that the MaximumFileSize property is not checked for that TraceLogRetentionOption value.
