Enjoy every bit: C# coding : Download Salesforce attachment to local disk using SOAP webservice Enterprise wsdl method (with SOQL selection)

Pre-requisite :

Select Target framework to 4.5.2
Install DeveloperForce.Force 2.1.0 (via nuget if VS2015 is used)
Import Enterprise wsdl as WebReference (for easy Type Casting , partner wsdl also work but need more code lines.)
Update 2 ListViewRecordColumn[][] in Reference.cs to ListViewRecordColumn[].
Otherwise, error as below will be shown :
Cannot convert type 'SaleForceBase.SaleForceRef.ListViewRecordColumn[]' ...

                // Download the attachment
