.NET Framework Class Library

Process..::.PrivateMemorySize64 Property

Gets the amount of private memory allocated for the associated process.

Namespace: System.Diagnostics
Assembly: System (in System.dll)

Syntax

Visual Basic (Declaration)

<ComVisibleAttribute(False)> _
Public ReadOnly Property PrivateMemorySize64 As Long

Visual Basic (Usage)

Dim instance As Process
Dim value As Long

value = instance.PrivateMemorySize64

[ComVisibleAttribute(false)]
public long PrivateMemorySize64 { get; }

Visual C++

[ComVisibleAttribute(false)]
public:
property long long PrivateMemorySize64 {
    long long get ();
}

JScript

public function get PrivateMemorySize64 () : long

Property Value

Type: System..::.Int64
The amount of memory, in bytes, allocated for the associated process that cannot be shared with other processes.

Exceptions

Exception	Condition
PlatformNotSupportedException	The platform is Windows 98 or Windows Millennium Edition (Windows Me), which does not support this property.

Remarks

The value returned by this property represents the current size of memory used by the process that cannot be shared with other processes.

This property can be used to monitor memory usage on computers with 32-bit processors or 64-bit processors. The property value is equivalent to the Private Bytes performance counter for the process.

Windows 98, Windows Millennium Edition Platform Note:

This property is not supported on Windows 98 or Windows Millennium Edition (Windows Me).

Examples

The following code example starts an instance of the Notepad application. The example then retrieves and displays various properties of the associated process. The example detects when the process exits, and displays its exit code and peak memory statistics.
