Visual挂起GetThreadWaitChain WCT调用

Question

我正在尝试WCT，我想打电话给GetThreadWaitChain，我以前有过一些关于这个话题的问题，但是我最近有一些奇怪的行为。在我调用GetThreadWaitChain函数时，我的Visual使用提示消息挂起：

vhost32.exe已停止工作

输出windows消息：

The program '[9068] testWCT.vshost.exe' has exited with code -1073740940 (0xc0000374).

每次我达到那个功能我的视觉工作室就挂起..。

GetThreadWaitChain文档：

https://msdn.microsoft.com/en-us/library/windows/desktop/ms679364(v=vs.85).aspx

这是我的密码：

internal void CollectWaitInformation(ClrThread thread)
{
    var g_WctHandle = OpenThreadWaitChainSession(0, 0);

    uint threadID = thread.OSThreadId;

    WAITCHAIN_NODE_INFO[] NodeInfoArray = new WAITCHAIN_NODE_INFO[16];


    int isCycle = 0;
    int count = 16;

    // Make a synchronous WCT call to retrieve the wait chain.
    bool result = GetThreadWaitChain(g_WctHandle,
                            IntPtr.Zero,
                            WCTP_GETINFO_ALL_FLAGS,
                            threadID, ref count, NodeInfoArray, out isCycle);

    if (!result)
    {
        //error
    }

    //Finaly ...
    CloseSession(g_WctHandle);
}

[DllImport("Advapi32.dll")]
public static extern IntPtr OpenThreadWaitChainSession(OpenThreadChainFlags Flags, DWORD callback);

[DllImport("Advapi32.dll")]
public static extern bool GetThreadWaitChain(
    IntPtr WctHandle,
    IntPtr Context,
    UInt32 Flags,
    uint ThreadId,
    ref int NodeCount,
    [MarshalAs(UnmanagedType.LPArray, SizeParamIndex = 4)]
    [In, Out]
    WAITCHAIN_NODE_INFO[] NodeInfoArray,
    out int IsCycle
);

[StructLayout(LayoutKind.Sequential)]
public struct WAITCHAIN_NODE_INFO
{
    public WCT_OBJECT_TYPE ObjectType;
    public WCT_OBJECT_STATUS ObjectStatus;

    public struct LockObject
    {
        string ObjectName;
        LARGE_INTEGER Timeout;
        BOOL Alertable;
    }
    public struct ThreadObject
    {
        DWORD ProcessId;
        DWORD ThreadId;
        DWORD WaitTime;
        DWORD ContextSwitches;
    }
}

}

我尝试在相同的进程上运行C++代码，这是从MSDN：https://msdn.microsoft.com/en-us/library/windows/desktop/ms681418(v=vs.85).aspx获得的。

结果是:所有线程都出现了0x57错误。对应于MSDN的ERROR_INVALID_PARAMETER：

https://msdn.microsoft.com/en-us/library/windows/desktop/ms681382(v=vs.85).aspx

这很奇怪因为我没有更改C++代码..。

关于同一主题的前一个问题：WCT GetThreadWaitChain call allways return false

我以错误的方式声明了WAITCHAIN_NODE_INFO结构(我的联盟是错误的)--这是原始结构：

我一宣布正确，堆腐败就停止了，一切都正常.
