Compiling C# Code From Command Prompt

Quite often, I quickly need to test a small piece of code and if you’re doing some customization on SharePoint, I hate to open project, apply the code, publish, and deploy over the server (retract, remove and redeploy!). I post this, so I can copy and paste and run the code quickly.

using System;

class TestClass
    static void Main(string[] args)
	Console.WriteLine("Hello World!");

       // Keep the console window open in debug mode.
        Console.WriteLine("Press any key to exit.");

Run command prompt as administrator and change the directory as follows

C:\Windows\system32>cd C:\Windows\Microsoft.NET\Framework64\v4.0.30319
C:\Windows\Microsoft.NET\Framework64\v4.0.30319>csc   -out:"C:\EPM\Code\my code.exe" C:\epm\code\main.cs

Adding Resource Calendar Exceptions Programmatically

ResourceDataSet rds = _resourceClient.ReadResource(new Guid(resGuid));

// be sure that the resource is checked out !

if (rds.CalendarExceptions != null)
for (int i = 0; i &lt; rds.CalendarExceptions.Rows.Count; i++)
// check row data...

// delete row if necessary
// don´t use GetChanges() method on the dataset !
_resourceClient.UpdateResources(resourceDataSet, false, false);

// Read resource data again
rds = _resourceClient.ReadResource(new Guid(resGuid));

// create new datarow
ResourceDataSet.CalendarExceptionsRow exceptionsRow = rds.CalendarExceptions.NewCalendarExceptionsRow();

// set necessary data for the new exception row here

// update the resource again
_resourceClient.UpdateResources(resourceDataSet, false, false);

// don´t forget to check in the resource
