Clone CRM Record CRM 2011

Many times while working on CRM 2011, we come across a situation to clone the quote or invoice records. Immediately we will start writing the code for getting the record and creating the same record again and continue the same for child records i.e. quote products or invoice lines etc...

Even I have came across the same situation then my team lead and me wrote a generic method for cloning CRM records.

Here is that method...

        #region CloneRecord

                /// <summary>
                /// Method to Clone CRM Record.
                /// </summary>
                /// <param name="strEntityName">Parent entity name ex: invoice</param>
                /// <param name="strParentEntityPKAttrName">Parent primary attribute name ex:invoiceid</param>
                /// <param name="guidParent">Guid of the parent record</param>
                /// <param name="strAttributesToFetch">Selected attributes to copy from one record to another. If you wanna copy all records,
                /// just send the parameter as null then the considers all attributes.</param>

                /// <param name="strArrRemoveParentAttributes">Attributes to remove from parent entity.</param>

                /// <param name="strChildEntity">Child entity name ex: invoicedetail</param>
                /// <param name="strChildEntityFKAttrName">Child primary attriubute name ex: invoicedetailid</param>
                /// <param name="strArrRemoveChildCols">Attributes to remove from child entity</param>
               /// <returns>Guid of the parent record</returns>

                {
