Search Results for "MEMORYSTATUSEX" in [All]Structures1: MEMORYSTATUS The CLR offer us no way to tell us that memory is getting tight. Many think this API provides the best solution. This is mentioned by Jeffrey Richter in his book 'CLR via C#' ISBN: 0-7356-2163-2. It is useful in determining if your system is under excessive memory load by looking at the dwMemoryLoad member of the MEMORYSTATUSEX structure. If this value is > 80 (per Mr. Richter in his discussion of Garbage Collection), it is an indication that you might want to consider converting some strong references into weak references. Remember that a weakreference type will be collected when Generation 0 is full, so it is not a good technique for caching (as many seem to think).
