Delete azure string storage line without checking for availability

Question

I have been using azure table storage for many years, and I'm not sure what the “right” way to do it is with the new WindowsAzure.Storage library, version 5.0.1-preview (for use in the new ASP.NET 5):

Problem: Given the partition key and row key, delete the row without first checking for its existence, and without failing if it does not exist.

Current solution: This code works ... but exception handling is confusing:

public async Task DeleteRowAsync(CloudTable table, string partition, string row)
{
    var entity = new DynamicTableEntity(partition, row);
    entity.ETag = "*";

    var op = TableOperation.Delete(entity);
    try
    {
        await table.ExecuteAsync(op);
    }
    catch (Exception ex)
    {
        var result = RequestResult.TranslateFromExceptionMessage(ex.Message);
        if (result == null || result.HttpStatusCode != 404)
            throw ex;
    }
}

Questions:

• TranslateFromExceptionMessage... WrappedStorageException ( , ). - / 404 ? - , , ?

• StorageException. , , StorageException.RequestInformation.HttpStatusCode, . "" XML ?

• , ?
