Consistency Enumeration

Specifies a reliability contract.

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

[SerializableAttribute]
public enum Consistency

Member nameDescription
MayCorruptProcessIn the face of exceptional conditions, the CLR makes no guarantees regarding state consistency; that is, the condition might corrupt the process.
MayCorruptAppDomainIn the face of exceptional conditions, the common language runtime (CLR) makes no guarantees regarding state consistency in the current application domain.
MayCorruptInstanceIn the face of exceptional conditions, the method is guaranteed to limit state corruption to the current instance.
WillNotCorruptStateIn the face of exceptional conditions, the method is guaranteed not to corrupt state.
NoteNote
This does not guarantee that the method will never fail; however, it does guarantee that such a failure will never corrupt state.

The Consistency enumeration is used as a parameter to the ReliabilityContractAttribute attribute to specify the reliability guarantee on a given method.

The following code example demonstrates the use of the Consistency enumeration when specifying a constrained execution region for a method. This code example is part of a larger example provided for the ReliabilityContractAttribute constructor.


[ReliabilityContract(Consistency.WillNotCorruptState, Cer.Success)]
[MethodImpl(MethodImplOptions.NoInlining)]
void StackDepth2()
{
    try
    {
        consistentLevel2 = false;
        if (depth == 2)
            Thread.Sleep(-1);
        StackDepth3();
    }
    finally
    {
        consistentLevel2 = true;
    }
}
