I am Calling .Dispose() method on objects, does it helps in Garbage Collection?
Please find an example below;

    ... //connection, command and adapter realated statements.
    adapter.Fill(recordSet);
    return recordSet;
}

    {
        recordSet.Dispose();
    }
    recordSet=null;
    GC.Collect();
    GC.Collect(2);
}

推荐答案

垃圾回收最好留给其自己的设备使用，请勿尝试使用GC.Collect对其进行强制.

Dispose并不能真正帮助垃圾回收，但是可以通过在垃圾回收之前释放非托管资源来实现垃圾回收.

using语句会为您完成所有这些异常操作.

Garbage collection is best left to its own devices, don''t try to coerce it with GC.Collect.

Dispose doesn''t really help with garbage collection, but it does help by releasing unmanaged resources before they get GCed.

A using statement does all that exception stuff for you btw.
