vb.net获取内存总量,已使用量,

总量:My.Computer.Info.TotalPhysicalMemory

可用的:My.Computer .Info .AvailablePhysicalMemory

已使用量=总量-可用的

vb.net 读取内存失败 求高手解答

你是想读取游戏进程吧 这个问题刚开始也 让我郁闷了很久 其实很多 游戏对读取内存做了特殊处理 常规的 调用api打开进程 读取内存 无效可以尝试 用token 直接调用就ok了 返回true说明调用成功下面是详细代码 Public Class ToKen

#Region "常数及结构声明"

Private Const SE_PRIVILEGE_ENABLED As Int32 = 2

Private Const EWX_SHUTDOWN As Int32 = 1

Private Const EWX_REBOOT As Int32 = 2

Private Const EWX_LOGOFF As Int32 = 0

Private Structure LUID_AND_ATTRIBUTES

Public pLuid As LUID

Public Attributes As Integer

End Structure

Private Structure LUID

Dim LowPart As Int32

Dim HighPart As Int32

End Structure

Private Structure TOKEN_PRIVILEGES

Public PrivilegeCount As Integer

Public Privileges As LUID

Public Attributes As Int32

End Structure

#End Region#Region "API声明"

Private Declare Function LookupPrivilegeValue Lib "advapi32.dll" Alias "LookupPrivilegeValueA" (ByVal lpSystemName As String, ByVal lpName As String, ByRef lpLuid As LUID) As Int32

Private Declare Function AdjustTokenPrivileges Lib "advapi32.dll" (ByVal TokenHandle As IntPtr, ByVal DisableAllPrivileges As Int32, ByRef NewState As TOKEN_PRIVILEGES, ByVal BufferLength As Int32, ByRef PreviousState As TOKEN_PRIVILEGES, ByRef ReturnLength As Int32) As Int32

Private Declare Function OpenProcessToken Lib "advapi32.dll" (ByVal ProcessHandle As IntPtr, ByVal DesiredAccess As Integer, ByRef TokenHandle As IntPtr) As Boolean

#End Region

#Region "获取全部权限"

Public Function ToKenPrivileges() As Boolean

Dim hdlTokenHandle As Integer

Dim tmpLuid As LUID

Dim tkp As TOKEN_PRIVILEGES

Dim tkpNewButIgnored As TOKEN_PRIVILEGES

Dim lBufferNeeded As Integer

Dim currentProcess As Process = Process.GetCurrentProcess()

If OpenProcessToken(currentProcess.Handle, HF00FF, hdlTokenHandle) Then

LookupPrivilegeValue("", "SeDebugPrivilege", tmpLuid)

tkp.PrivilegeCount = 1

tkp.Privileges = tmpLuid

tkp.Attributes = SE_PRIVILEGE_ENABLED

Return AdjustTokenPrivileges(hdlTokenHandle, False, tkp, Len(tkpNewButIgnored), tkpNewButIgnored, lBufferNeeded)

End If

End Function

#End Region

vb.net如何读取指定地址的内存值并赋值给一个变量

用.ini文件来存储。比如内容是:[UserInfo]UserName=admin读取方式:charachUserName[20];GetPrivateProfileString("UserInfo","UserName",NULL,achUserName,20,"c:\\userInfo.ini");

vb.net如何获取当前进程的cpu和内存使用率?

使用wmi

类“Win32_Processor”中LoadPercentage属性为当前的cpu使用率

示例代码: Private Sub Timer1_Timer()

Dim WMI服务 As Object

Dim 对象 As Object

Dim 子对象 As Object

Dim 电脑名 As String

Dim 刷新 As Long

刷新 = 0

电脑名 = "." '表示本地计算机

Set WMI服务 = GetObject("winmgmts://" 电脑名 "/root/cimv2")

Set 对象 = WMI服务.InstancesOf("Win32_Processor")

Me.CurrentX = 0

Me.CurrentY = 0

For Each 子对象 In 对象

If 刷新 = 0 Then

刷新 = 1

Me.Cls

End If

Me.Print 子对象.Name "[" 子对象.CurrentClockSpeed "Hz] 使用率:" _

子对象.LoadPercentage "%"

Next

End Sub

vb.net获取内存总量

应用里添加 System.Management

文件前加上

Imports System.Management

''' summary

''' 获取系统内存大小

''' /summary

''' returns内存大小(单位Byte)/returns

Private shared Function GetPhisicalMemory()As Long

dim searcher = new ManagementObjectSearcher()   '用于查询一些如系统信息的管理对象

searcher.Query = new SelectQuery("Win32_PhysicalMemory ", "", new string() { "Capacity" })'设置查询条件 

dim collection = searcher.Get()   '获取内存容量 

dim em = collection.GetEnumerator()

dim capacity as long= 0

While (em.MoveNext())

dim baseObj = em.Current

If (baseObj.Properties("Capacity").Value IsNot Nothing) Then                    

Try

capacity += long.Parse(baseObj.Properties("Capacity").Value.ToString())

Catch

return 0

End Try

End If 

End While

return capacity

End Function
