∟Using "Process" Class to Show Memory Usages

This section provides a tutorial example on how to retrieve memory usage statistics of your application using methods and properties of the System.Diagnostics.Process class.

If you want to know memory usage statistics of your C# application, you can use these methods and properties from System.Diagnostics.Process class provided in .NET 4:

GetCurrentProcess() - Static method to return a Process object that represents the current process.
PagedSystemMemorySize64 - Property to get the amount of paged system memory allocated for this process.
NonpagedSystemMemorySize64 - Property to get the amount of nonpaged system memory allocated for this process.
PagedMemorySize64 - Property to get the amount of paged memory allocated for this process.
PrivateMemorySize64 - Property to get the amount of private memory allocated for this process.
VirtualMemorySize64 - Property to get the amount of the virtual memory allocated for this process.
WorkingSet64 - Property to get the amount of physical memory allocated for this process.

Here is my tutorial example on using these memory related methods and properties:

// MemoryUsage.cs
// Copyright (c) 2010 HerongYang.com. All Rights Reserved.

using System;
public class MemoryUsage {
   public static void Main() {
      System.Diagnostics.Process proc
         = System.Diagnostics.Process.GetCurrentProcess();
      Console.WriteLine("Current process: {0}", proc.ToString());

      Console.WriteLine("Private Memory: {0}",
         proc.PrivateMemorySize64);
      Console.WriteLine("Virtual Memory: {0}",
         proc.VirtualMemorySize64);
      Console.WriteLine("Working Set: {0}",
         proc.WorkingSet64);
      Console.WriteLine("Paged Memory: {0}",
         proc.PagedMemorySize64);
      Console.WriteLine("Paged System Memory: {0}",
         proc.PagedSystemMemorySize64);
      Console.WriteLine("Non-paged System Memory: {0}",
         proc.NonpagedSystemMemorySize64);
   }
}

I compiled it with .NET 4 C# compiler and got this output:

C:\herong>\Windows\Microsoft.NET\Framework\v4.0.30319\csc
   MemoryUsage.cs

C:\herong>MemoryUsage.exe
