How to use batch update

For batch update, the following parts are needed:.
A BatchAppendKeywordValues object which requires DocId, FieldName and Keyword property.
Also, you can create a BatchUpdateProcess object which needs to be created with a source of BatchUpdateDocumentsSource or BatchUpdateDialogExpressionSource.
The index fields which you want to change in those objects are located in the BatchUpdateProcessData Field property.

How to append to a keyword index field.

List<int> documentIds = new List<int>()
{
    123
};

List<string> keywords = new List<string>()
{
    "Value to append"
};

BatchUpdateIndexFieldsResult batchUpdateIndexFieldsResult = BatchAppendKeywordValuesInFileCabinet(fileCabinet, documentIds, keywords, "DBNAMEKEYWORDINDEXFIELD");

public static BatchUpdateIndexFieldsResult BatchAppendKeywordValuesInFileCabinet(FileCabinet fileCabinet, List<int> documentIds, List<string> keywords, string fieldName)
{
    return fileCabinet.PostToBatchUpdateRelationForBatchUpdateIndexFieldsResult(
    new BatchAppendKeywordValues
    {
        DocId = documentIds,
        Keyword = keywords,
        FieldName = fieldName
    });
}

};

List<string> keywords = new List<string>()
{

};

DeserializedHttpResponse<BatchUpdateIndexFieldsResult> batchUpdateIndexFieldsResult = await BatchAppendKeywordValuesInFileCabinetAsync(fileCabinet, documentIds, keywords, "DBNAMEKEYWORDINDEXFIELD");

public static async Task<DeserializedHttpResponse<BatchUpdateIndexFieldsResult>> BatchAppendKeywordValuesInFileCabinetAsync(FileCabinet fileCabinet, List<int> documentIds, List<string> keywords, string fieldName)
{
    return await fileCabinet.PostToBatchUpdateRelationForBatchUpdateIndexFieldsResultAsync(

        DocId = documentIds,
        Keyword = keywords,
        FieldName = fieldName
    });

BatchUpdateProcess

Sync

Use list of document ids for batch update.

List<int> documentIds = new List<int>()
{
    123
}

List<DialogExpressionCondition> updateFields = new List<DocumentIndexField>()
{
    DocumentIndexField.Create("DBFIELDNAME", "VALUE")
}

BatchUpdateIndexFieldsResult batchUpdateIndexFieldsResult = BatchUpdateInFileCabinet(fileCabinet, documentIds, updateFields);

public static BatchUpdateIndexFieldsResult BatchUpdateInFileCabinet(FileCabinet fileCabinet, List<int> documentIds, List<DialogExpressionCondition> updateFields)
{
    return fileCabinet.PostToBatchUpdateRelationForBatchUpdateIndexFieldsResult(new BatchUpdateProcess
    {
        Source = new BatchUpdateDocumentsSource
        {
            Id = documentIds
        },
        Data = new BatchUpdateProcessData
        {
            Field = updateFields
        }
    });
}

Use search expression for batch update.

BatchUpdateDialogExpressionSource batchUpdateDialogExpressionSource = new BatchUpdateDialogExpressionSource
{
    Expression = new DialogExpression
    {
        Condition = new List<DialogExpressionCondition>
        {
            DialogExpressionCondition.Create("DBFIELDNAME", "VALUE")
        },
        Operation = DialogExpressionOperation.And
    }
};

List<DialogExpressionCondition> updateFields = new List<DocumentIndexField>()
{
    DocumentIndexField.Create("DBFIELDNAME", "VALUE")
};

BatchUpdateIndexFieldsResult batchUpdateIndexFieldsResult = BatchUpdateInFileCabinet(fileCabinet, documentIds, updateFields);

public static BatchUpdateIndexFieldsResult BatchUpdateInFileCabinet(FileCabinet fileCabinet, BatchUpdateDialogExpressionSource batchUpdateDialogExpressionSource, List<DialogExpressionCondition> updateFields)
{
    return fileCabinet.PostToBatchUpdateRelationForBatchUpdateIndexFieldsResult(new BatchUpdateProcess
    {
        Source = batchUpdateDialogExpressionSource,
        Data = new BatchUpdateProcessData
        {
            Field = updateFields
        }
    });
}

Use list of document ids for batch update.

public static async Task
List<int> documentIds = new List<int>()
{
    1
};

List<DialogExpressionCondition> updateFields = new List<DocumentIndexField>()
{
    DocumentIndexField.Create("DBFIELDNAME", "VALUE")
};

DeserializedHttpResponse<BatchUpdateIndexFieldsResult> batchUpdateIndexFieldsResultAsync = await BatchUpdateInFileCabinetAsync BatchUpdateInFileCabinet(fileCabinet, documentIds, updateFields);

public static async Task<DeserializedHttpResponse<BatchUpdateIndexFieldsResult>> BatchUpdateInFileCabinet(FileCabinet fileCabinet, List<int> documentIds, List<DialogExpressionCondition> updateFields)
{
    return await fileCabinet.PostToBatchUpdateRelationForBatchUpdateIndexFieldsResultAsync(new BatchUpdateProcess
    {
        Source = new BatchUpdateDocumentsSource
        {
            Id = documentIds
        },
        Data = new BatchUpdateProcessData
        {
            Field = updateFields
        }
    });
}

            DialogExpressionCondition.Create("DBFIELDNAME", "VALUE")
        },
        Operation = DialogExpressionOperation.And
    }
};

List<DialogExpressionCondition> updateFields = new List<DocumentIndexField>()
{
    DocumentIndexField.Create("DBFIELDNAME", "VALUE")
};

DeserializedHttpResponse<BatchUpdateIndexFieldsResult> batchUpdateIndexFieldsResultAsync = await BatchUpdateInFileCabinetAsync(fileCabinet, documentIds, updateFields);

    {
        Source = batchUpdateDialogExpressionSource,
        Data = new BatchUpdateProcessData

            Field = updateFields
        }
