示例1: DetectKeyChange
private void DetectKeyChange(InternalEntityEntry entry, IProperty property, Sidecar snapshot)
{
if (!snapshot.HasValue(property))
{
return;
}
var keys = property.FindContainingKeys().ToList();
var foreignKeys = property.FindContainingForeignKeys(entry.EntityType).ToList();
if (keys.Count > 0
|| foreignKeys.Count > 0)
{
var snapshotValue = snapshot[property];
var currentValue = entry[property];
// Note that mutation of a byte[] key is not supported or detected, but two different instances
// of byte[] with the same content must be detected as equal.
if (!StructuralComparisons.StructuralEqualityComparer.Equals(currentValue, snapshotValue))
{
var stateManager = entry.StateManager;
if (foreignKeys.Count > 0)
{
stateManager.Notify.ForeignKeyPropertyChanged(entry, property, snapshotValue, currentValue);
foreach (var foreignKey in foreignKeys)
{
stateManager.UpdateDependentMap(entry, snapshot.GetDependentKeyValue(foreignKey), foreignKey);
}
}
if (keys.Count > 0)
