Feature service AddAttachments method

Adds attachments to a layer and returns the results.

EditResult[] AddAttachments(int LayerOrTableID, AttachmentData[] AttachmentDataArray, string VersionName, boolean RollbackOnFailure, boolean RollbackOnFailureSpecified)




The ID of the layer in which to add the attachments.


The array of attachments to be added.


The geodatabase version to apply the edits. This parameter only applies to FeatureServices that expose geodatabases. If not specified, edits are applied to the published map's version.


RollbackOnFailure determines whether edits will be applied in a transactional manner. If set to true, and any of the edits fail, the entire edit operation will fail. If set to false, if some portion of the edits fail, they will not be applied. However, the edit operation will succeed and all others edits will be applied.

Not all data supports setting this parameter. Query the SupportsRollbackonFailureParameter property of the DataObjectTable to determine whether or not a layer supports setting this parameter. If SupportsRollbackonFailureParameter = false for a layer, then when editing this layer, RollbackOnFailure will always be true, regardless of how the parameter is set. However, if SupportsRollbackonFailureParameter = true, this means the RollbackOnFailure parameter can be set to true or false on edit operations.


Indicates if RollbackOnFailure is specified.

Return Value

This method returns an array of EditResult objects whose order is consistent with the order of the features or objects in the input AttachmentDataArray parameter. Each contains the AttachmentID (EditResult.OID) assigned to the attachment when it was added. If adding of a feature or object fails, the returned object will have the error code (EditResult.Code) and description (EditResult.Description).


Some AttachmentData properties, such as AttachmentID that is part of the AttachmentInfo property, are not editable. If these properties are set, they will be ignored when applied to the service.
