如何确定vb.net中未使用的总物理内存

Question

I want to limit the number of threads I create based on the amount of free physical memory. For instance I want to stop making new threads once I reach the point that there is only 7GB of real memory left. How would I do so?

Answer 1

You can use Devices.ComputerInfo to get the total amount of free physical memory:

Dim info = New Microsoft.VisualBasic.Devices.ComputerInfo()
Dim gb = info.AvailablePhysicalMemory / 1024 / 1024 / 1024
While gb >= 7
    ' start your threads here ... '
    gb = info.AvailablePhysicalMemory / 1024 / 1024 / 1024
End While
