Entity Framework Extensions UseAudit

Description

When the UseAudit property is true, the AuditEntries property stores auditing metadata about INSERTED, UPDATED, and DELETED rows and values.

/// <summary>Gets or sets the `UseAudit` property. When the `UseAudit` property is `true`, the [AuditEntries](audit-entries) property stores auditing metadata about `INSERTED`, `UPDATED`, and `DELETED` rows and values.</summary>
public bool UseAudit { get; set; }

Example

We will demonstrate how to use the UseAudit and AuditEntries properties.

Execute

We will execute a BulkMerge on a list that contains 1 new customer, and 2 existing customers.

We will use the following BulkOptions:

  • UseAudit: To enable the auditing feature.
  • AuditEntries: To retrieve auditing metadata.

Code

// Execute
List<AuditEntry> auditEntries = new List<AuditEntry>();            
context.BulkMerge(list, options =>
{
    options.UseAudit = true;
    options.AuditEntries = auditEntries;
});

// Result
FiddleHelper.WriteTable("1 - AuditEntry", auditEntries);
FiddleHelper.WriteTable("2 - AuditEntryItem", auditEntries.SelectMany(x => x.Values));

Try it: .NET Core | .NET Framework

Result

We outputted all AuditEntry and AuditEntryItem auditing metadata.
