GCSettings.LargeObjectHeapCompactionMode Property
[This topic is preliminary and is subject to change.]
Gets or sets a value that indicates whether a full blocking garbage collection compacts the large object heap (LOH).
Namespace: System.Runtime
Assembly: mscorlib (in mscorlib.dll)
Property Value
Type: System.Runtime.GCLargeObjectHeapCompactionModeOne of the enumeration values that indicates whether a full blocking garbage collection compacts the LOH.
The default value of the LargeObjectHeapCompactionMode property is GCLargeObjectHeapCompactionMode.Default, which indicates that the LOH is not compacted during garbage collections. If you assign the property a value of GCLargeObjectHeapCompactionMode.CompactOnce, the LOH is compacted during the next blocking garbage collection, and the property value is reset to GCLargeObjectHeapCompactionMode.Default.
If the LargeObjectHeapCompactionMode property is set to GCLargeObjectHeapCompactionMode.Default, the next full blocking garbage collection (and compaction of the LOH) occurs at an indeterminate future time. You can compact the LOH immediately by using code like the following:
Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
