Gets or sets the number of files to be kept open. Setting this to a higher value may improve performance in a situation where a single File target is writing to many files (such as splitting by level or by logger).

Syntax

Copy

public int OpenFileCacheSize { get; set; }

Public Property OpenFileCacheSize As Integer
	Get
	Set

Dim instance As FileTarget
Dim value As Integer

value = instance.OpenFileCacheSize

instance.OpenFileCacheSize = value

member OpenFileCacheSize : int with get, set

Property Value

Type: Int32

Remarks

The files are managed on a LRU (least recently used) basis, which flushes the files that have not been used for the longest period of time should the cache become full. As a rule of thumb, you shouldn't set this parameter to a very high value. A number like 10-15 shouldn't be exceeded, because you'd be keeping a large number of files open which consumes system resources.
