Clearing up large fields from memory in long lived objects

.NET 3.5, I've got some classes which stores up to 1MB of strings. Even though I need the object for a really long time I don't need to store the string for a long time.

How can I truly remove the string from memory without disposing the parent object.

Is it a good practice to use "myString = null" in this case? or shall wrap it in a private dsposable class or something?

It's possible that you're referencing or copying the string somewhere else in the program (like in a TextBox?), which is keeping it alive in memory.

IDisposable has nothing to do with memory management. Assigning null to a private variable will do just fine. And see if Flyweight fits you.
