Using Disposable object

First method is to use the “Using” keyword which is quite clean and simple

using (IDisposable obj = new DataTable())
{
//do your logic with obj variable
}

Second method is to use Try and finally keyword

IDisposable obj = null;

try
{
obj = new DataTable();
}
finally
{
if (obj != null)
{
obj.Dispose();
}
}
