How to avoid memory leakage in SAP B1 DI API

The thumb rule goes like this, if you instantiate a DI API object, you have to release it. if you don't release it explicitly, it will result in memory leaks.

You can use a ReleaseComObject method to release the object memory. In case if you try to release a null object, it will throw an exception.

So, it will be better to have a null check before you try to release the object.

Sample snippet:

if (obj != null)
System.Runtime.InteropServices.Marshal.ReleaseComObject(obj);
