System.Diagnostics.ThreadPriorityLevel Enumeration

Specifies the priority level of a thread.

Syntax

public enum ThreadPriorityLevel

Remarks

Every thread has a base-priority level determined by the thread's priority value and the priority class of its process. The operating system uses the base-priority level of all executable threads to determine which thread gets the next slice of processor time.

The priority level is not an absolute value, but instead is a range of priority values. The operating system computes the priority by using the process priority class to determine where, in the range specified by the ProcessThread.PriorityLevel property, to set the thread's priority.

Members

Member NameDescription
AboveNormal

Specifies one step above the normal priority for the associated System.Diagnostics.ProcessPriorityClass.

BelowNormal

Specifies one step below the normal priority for the associated System.Diagnostics.ProcessPriorityClass.

Highest

Specifies highest priority. This is two steps above the normal priority for the associated System.Diagnostics.ProcessPriorityClass.

Idle

Specifies idle priority. This is the lowest possible priority value of all threads, independent of the value of the associated System.Diagnostics.ProcessPriorityClass.

Lowest

Specifies lowest priority. This is two steps below the normal priority for the associated System.Diagnostics.ProcessPriorityClass.

Normal

Specifies normal priority for the associated System.Diagnostics.ProcessPriorityClass.

TimeCritical

Specifies time-critical priority. This is the highest priority of all threads, independent of the value of the associated System.Diagnostics.ProcessPriorityClass.
