Get the program’s memory usage in C#

This example uses the following code to display information about its memory usage.

// Display information about the current process's memory usage.
private void Form1_Load(object sender, EventArgs e)
{
    Process proc = Process.GetCurrentProcess();
    AddItem(lvMemory, "Min Working Set",
        ((double)proc.MinWorkingSet).ToFileSize());
    AddItem(lvMemory, "Max Working Set",
        ((double)proc.MaxWorkingSet).ToFileSize());
    AddItem(lvMemory, "Non-paged Memory Size",
        ((double)proc.NonpagedSystemMemorySize64).ToFileSize());
    AddItem(lvMemory, "Paged Memory Size",
        ((double)proc.PagedMemorySize64).ToFileSize());
    AddItem(lvMemory, "Paged System Memory Size",
        ((double)proc.PagedSystemMemorySize64).ToFileSize());
    AddItem(lvMemory, "Peak Paged Memory Size",
        ((double)proc.PeakPagedMemorySize64).ToFileSize());
    AddItem(lvMemory, "Peak Virtual Memory Size",
        ((double)proc.PeakVirtualMemorySize64).ToFileSize());
    AddItem(lvMemory, "Peak Working Set",
        ((double)proc.PeakWorkingSet64).ToFileSize());
    AddItem(lvMemory, "Virtual Memory Size",
        ((double)proc.VirtualMemorySize64).ToFileSize());
    AddItem(lvMemory, "Working Set",
        ((double)proc.WorkingSet64).ToFileSize());

    lvMemory.Columns[0].AutoResize(
        ColumnHeaderAutoResizeStyle.ColumnContent);
    lvMemory.Columns[1].AutoResize(
        ColumnHeaderAutoResizeStyle.ColumnContent);
}

The code get the program’s Process object and then uses its properties to learn about its memory usage.

The AddItem method simply adds a new item and subitems to the lvMemory ListView control. The ToFileSize extension method converts a memory size in bytes into a more useful unit such as KB or MB. Download the example and look at the code to see the details.
