GCSettings.LatencyMode Property


Gets or sets the current latency mode for garbage collection.

Namespace:   System.Runtime
Assembly:  mscorlib (in mscorlib.dll)

public static GCLatencyMode LatencyMode {
	[HostProtectionAttribute(SecurityAction.LinkDemand, MayLeakOnAbort = true)]

Property Value

Type: System.Runtime.GCLatencyMode

One of the enumeration values that specifies the latency mode.

Exception Condition

The LatencyMode property is being set to an invalid value.


The LatencyMode property cannot be set to GCLatencyMode.NoGCRegion.

You can reduce the level of intrusiveness of garbage collection in your application by setting the GCLatencyMode to LowLatency during critical operations. After such operations are completed, return to a higher latency mode so that more objects can be reclaimed to increase memory.

Ordinarily, you set the value of the LatencyMode property to define the garbage collector's latency mode. However, you cannot set the no GC region latency mode by assigning the GCLatencyMode.NoGCRegion enumeration value to the LatencyMode property. Instead, you call the GC.TryStartNoGCRegion method to begin the no GC region latency mode, and you call the GC.EndNoGCRegion to end it.

See Latency Modes for a discussion of how the runtime configuration settings for garbage collection affect the default value of the GCLatencyMode enumeration.
