.NET Bulk Operations ColumnMappingAuditModeType

Description

The ColumnMappingAuditModeType enum represents if a specific property should be included or excluded from the auditing. The default value is ColumnMappingAuditModeType.Inherit.

You can include or exclude all properties with the Inherit value using the AuditModeType enum.

// The namespace is different because the https://bulk-operations.net/ library is used under the hood.
namespace Z.BulkOperations
{
    /// <summary>The `ColumnMappingAuditModeType` enum represents if a specific property should be included or excluded from the auditing. The default value is `ColumnMappingAuditModeType.Inherit`.</summary>
    public enum ColumnMappingAuditModeType
    {
        /// <summary>The name/value that represents if a specific property inherit from the AuditModeType (Default Value).</summary>
        Inherit,

        /// <summary>The name/value that represents if a specific property is included.</summary>
        Include,

        /// <summary>The name/value that represents if a specific property is excluded.</summary>
        Exclude
    }
}

Example

We will demonstrate how to exclude all properties to include only specific properties.

Mapping

We will use the following mapping:

To exclude all properties

bulk.AuditMode = AuditModeType.ExcludeAll;

To include specific properties

bulk.ColumnMappings.Add(
    new ColumnMapping<Customer>("CustomerID", true)
    {
        AuditMode = ColumnMappingAuditModeType.Include
    }
);
bulk.ColumnMappings.Add(
    new ColumnMapping<Customer>("Name")
    {
        AuditMode = ColumnMappingAuditModeType.Include
    }
);

Execute

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

Code

// Execute
List<AuditEntry> auditEntries = new List<AuditEntry>(); 
using (var bulk = new BulkOperation(connection))
{
    bulk.DestinationTableName = "Customer";
    bulk.UseAudit = true;

    bulk.AuditMode = AuditModeType.ExcludeAll;
    
    bulk.ColumnMappings.Add(
        new ColumnMapping<Customer>("CustomerID", true)
        {
            AuditMode = ColumnMappingAuditModeType.Include
        }
    );
    bulk.ColumnMappings.Add(
        new ColumnMapping<Customer>("Name")
        {
            AuditMode = ColumnMappingAuditModeType.Include
        }
    );
    bulk.BulkMerge(list);

    auditEntries = bulk.AuditEntries;
}

// Result
FiddleHelper.WriteTable(auditEntries.SelectMany(x => x.Values));

Try it: .NET Core | .NET Framework

Result

We outputted all AuditEntryItem auditing metadata. The only information that appears is about the CustomerID and Name property.
