The memory cache provider is built on top of the System.Runtime.Caching memory cache provider in the .NET Framework. It has been extended to support regions.
Defaults for the memory cache provider
• MaxMegabytes - 10
• MaxCacheItems - Int32.MaxValue
• DefaultExpirationInMinutes - 20
Example
public class MemoryCacheExample
{
public void MemoryCacheExampleUsage()
{
//Build parameters for the report
Dictionary<string, object> parms = new Dictionary<string, object>();
parms.Add("Month", DateTime.Now.Month);
parms.Add("Year", DateTime.Now.Year);
//Get the cache key based on the report parameters
string cacheKey = Cache.Instance.BuildCacheKey("MonthlySalesReport", parms);
//Get the report from the cache, if it does not exist, call the ReportLogic.MonthlySalesReport, save it to the cache and return it
List<ReportDetail> result = Cache.Instance.Get<List<ReportDetail>>(cacheKey, NetCachingLibraryTest.ReportLogic.MonthlySalesReport, parms);
}
}
