本文提供了一个示例代码，展示了如何使用C#和VB.NET进行内存管理，包括垃圾回收和工作集大小的设置，以减少应用程序的内存占用。

Sample Code:

//sample is probably a bad idea, but it will "trim down" the memory footprint of a .Net App (or at least the value reflected in Task Manager).

C#

   public class MemoryManagement{
        [DllImport("kernel32.dll")]
        public static extern bool SetProcessWorkingSetSize( IntPtr proc, int min, int max );

        public void FlushMemory() {
            GC.Collect() ;
            GC.WaitForPendingFinalizers() ;
            if(Environment.OSVersion.Platform == PlatformID.Win32NT) {
                SetProcessWorkingSetSize(System.Diagnostics.Process.GetCurrentProcess().Handle, -1, -1) ;
            }
        }
   }

VB.NET

     Friend Sub ReleaseMemory()
      Try
           GC.Collect()
           GC.WaitForPendingFinalizers()
           If Environment.OSVersion.Platform = PlatformID.Win32NT Then
            SetProcessWorkingSetSize(System.Diagnostics.Process.GetCurrentProcess().Handle, -1, -1)
           End If
      Catch
      End Try
     End Sub
