Powershell 添加具有结构参数的类型处理函数

我正在尝试将一个函数导入到PowerShell中，该函数的参数为Struct。我收到一个“找不到类型”错误，但我不确定如何包含它。任何帮助都将不胜感激

  $MethodDefinition = (
'[DllImport("kernel32.dll")]static extern int VirtualQueryEx(IntPtr hProcess, IntPtr lpAddress, out MEMORY_BASIC_INFORMATION lpBuffer, uint dwLength);')

$Kernel32 = Add-Type -MemberDefinition $MethodDefinition -Name 'Kernel32' -Namespace 'Win32' -PassThru

==编辑====

因此，此代码不会加载函数：

$MethodDefinition =
@'

public struct MEMORY_BASIC_INFORMATION
{
    public IntPtr BaseAddress;
    public IntPtr AllocationBase;
    public uint AllocationProtect;
    public uint RegionSize;
    public uint State;
    public uint Protect;
    public uint Type;
}

[DllImport("kernel32.dll", CharSet = CharSet.Unicode)]public static extern IntPtr OpenProcess(int dwDesiredAccess, bool bInheritHandle, int dwProcessId);
[DllImport("kernel32.dll", CharSet = CharSet.Unicode)]public static extern bool ReadProcessMemory(int hProcess, int lpBaseAddress, byte[] lpBuffer, int     dwSize, ref int lpNumberOfBytesRead);
[DllImport("kernel32.dll")]static extern int VirtualQueryEx(IntPtr hProcess, IntPtr lpAddress, out MEMORY_BASIC_INFORMATION lpBuffer, uint dwLength);
'@

$Kernel32 = Add-Type -MemberDefinition $MethodDefinition -Name 'Kernel32' -Namespace 'Win32' -PassThru

但我在尝试访问函数时出错

代码：

错误：

 Method invocation failed because [Win32.Kernel32] doesn't contain a method named 'VirtualQueryEx'.

我哪里出错了？

如果我运行此命令，它会告诉我您缺少以下声明：

所以试试这个：

$MethodDefinition =
@'

public struct MEMORY_BASIC_INFORMATION
        {
            public IntPtr BaseAddress;
            public IntPtr AllocationBase;
            public uint AllocationProtect;
            public uint RegionSize;
            public uint State;
            public uint Protect;
            public uint Type;
        }


[DllImport("kernel32.dll")]
static extern int VirtualQueryEx(IntPtr hProcess, IntPtr lpAddress, out MEMORY_BASIC_INFORMATION lpBuffer, uint dwLength);
'@


$Kernel32 = Add-Type -MemberDefinition $MethodDefinition -Name 'Kernel32' -Namespace 'Win32' -PassThru

Hi jisaak（和Mathias），您的解决方案有效，但该方法不存在。您可以查看我的编辑吗？您的

VirtualQueryEx

没有标记为

public

，因此默认情况下它是

private

，因此对PowerShell方法解析不可见。

The type or namespace name 'MEMORY_BASIC_INFORMATION' could not be found (are you missing a using directive or an 
assembly reference?)

$MethodDefinition =
@'

public struct MEMORY_BASIC_INFORMATION
        {
            public IntPtr BaseAddress;
            public IntPtr AllocationBase;
            public uint AllocationProtect;
            public uint RegionSize;
            public uint State;
            public uint Protect;
            public uint Type;
        }


[DllImport("kernel32.dll")]
static extern int VirtualQueryEx(IntPtr hProcess, IntPtr lpAddress, out MEMORY_BASIC_INFORMATION lpBuffer, uint dwLength);
'@


$Kernel32 = Add-Type -MemberDefinition $MethodDefinition -Name 'Kernel32' -Namespace 'Win32' -PassThru
