C# – EpochTime

Snipplet code to convert current date time to epoch time
you may go to http://www.epochconverter.com/ to check the result.

public long GetEpochTime()
        {
            DateTime dtCurTime = DateTime.Now;
            DateTime dtEpochStartTime = Convert.ToDateTime("1/1/1970 00:00:00 AM");
            TimeSpan ts = dtCurTime.Subtract(dtEpochStartTime);

            long epochtime;
            epochtime = ((((((ts.Days * 24) + ts.Hours) * 60) + ts.Minutes) * 60) + ts.Seconds);
            return epochtime;
        }

SharePoint 2010 – return XmlDocument with WCF Rest WebService

Objective: to return XmlDocument from WCF REST WebService via URL.

Creating a WCF WebService is straight forward, but to create a WCF WebService to host under SharePoint 2010 you need extra steps to accomplish.
This is my first time to develop WCF RestFul WebService. Many of you may familiar with REST if you are the SharePoint Developer.

I will attach a zip file of a working solution at the end of this post.

To Create WCF Service

New Project -> WCF -> WCF Service Library
it will create 2 class files for you. (we need these 2 files)

To Create SharePoint WCF Service

New Project -> SharePoint -> Empty SharePoint Project
Map ISAPI SharePoint Folder
Create a text file and rename it to “BuckOfficesService.svc”
Create another text file and rename it to “web.config”
Copy 2 cs files from WCF Service Project (Rename them as BuckOfficeService.cs and IBuckOfficesService.cs)
Make sure those references added in the project as well

Microsoft.SharePoint
Microsoft.SharePoint.Client.Runtime
Microsoft.SharePoint.Security
System.ServiceModel
System.ServiceModel.Web

So I wanted to return a XmlDocument from Rest WCF WebService.
You need to make sure you add [XmlSerializerFormat] in your Interface class (it will return error when you try to run the service) before or after [ServiceContract]

Deploy the solution to your SharePoint Server.
Launch IE with http://localhost/_vti_bin/buckofficesservice.svc/getbuckoffices
