why dispose method is not for string object?

Question

why dispose method is not for string object in c#? As we know Dispose() is the method for dispose the object. But why it is not allows for string object or integer object?

Edited: What does the mean of managed object ?. Please guide me.

Answer 1

No, Dispose is the method to dispose resources not managed by the GC. String is just a regular, managed object and will thus be automatically reclaimed by garbage collection.

Answer 2

Dispose is to release all external resources, string and int are simple data types and have no external resources.
