Question

我正在使用https://technet.microsoft.com/en-us/library/ms345134(v=sql.90).aspx处找到的代码，但在跟踪关闭时会继续崩溃。

我在Windows 10 x64上运行Visual Studio 2017。它在Windows 10 x64和Windows 2012 R2 x64上失败，但适用于Windows 7 x86和Windows 2008 R2 x64。

我没有改变任何事情：通过从Profiler导出默认模板获取文件c：\ temp \ standard.tdf。我尝试了几个模板文件，仍然没有运气。我尝试了几个版本的SQL Server（2014年，2016年，2017年），没有任何乐趣。

这是我正在运行的代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
//reference: c:\Program Files (x86)\Microsoft SQL Server\140\SDK\Assemblies\Microsoft.SqlServer.ConnectionInfo.dll
using Microsoft.SqlServer.Management.Common;
// reference c:\Program Files (x86)\Microsoft SQL Server\140\SDK\Assemblies\Microsoft.SqlServer.ConnectionInfoExtended.dll
using Microsoft.SqlServer.Management.Trace;


namespace ConsoleApp1
{
    class Program
    {


        static void Main(string[] args)
        {
            TraceServer reader = new TraceServer();
            ConnectionInfoBase ci = new SqlConnectionInfo(".\\SQL2014");
            ((SqlConnectionInfo)ci).UseIntegratedSecurity = true;
            reader.InitializeAsReader(ci, @"c:\temp\standard.tdf");
            int eventNumber = 0;
            while (reader.Read())
            {
                Console.Write(reader.GetValue(0).ToString());
                eventNumber++;
                if (eventNumber == 10) break;
            }
            reader.Close();

            // debug reaches the end of the main method, then crashes
        }
    }
}

在EventViewer中，我找到了以下信息：

Faulting application name: ConsoleApp1.exe, version: 1.0.0.0, time stamp: 0x5a399d47
Faulting module name: KERNELBASE.dll, version: 10.0.16299.15, time stamp: 0x2cd1ce3d

我尝试了几个版本的SMO，但无济于事。在调试和发布中崩溃。在Windows 10和Windows 2012 R2中崩溃。

我没有想法。有什么指针吗？

我能够在自己的实验室机器上重现这个问题。

我在google上搜索了很多报告的异常代码：0x0020001。异常通常是托管代码加载非托管代码，其中非托管代码＆＃34;挂起＆＃34;并试图＆＃34;报告＆＃34;回到托管代码 - 但托管代码确实退出，因此它失败了。

我确实花了一些时间用ILSpy对dll文件进行逆向工程，以查看最终的结果。

查看Microsoft.SqlServer.Management.Trace.TraceServer.InitializeAsReader（）我们看到了这个：

// Microsoft.SqlServer.Management.Trace.TraceServer
public void InitializeAsReader(ConnectionInfoBase serverConnInfo, string profileFileName)
{
    try
    {
        this.rowsetCtrl = (TraceUtils.CreateInstance("\\Binn\\pfclnt.dll", "Microsoft.SqlServer.Management.Trace.CTraceObjectsRowsetController") as ITraceObjectsRowsetController);
        this.rowsetCtrl.Initialize(serverConnInfo, profileFileName);
        this.rowsetCtrl.InitSource(false);
        this.traceController = this.rowsetCtrl;
    }
    catch (Exception ex)
    {
        TraceUtils.FilterException(ex);
        throw new SqlTraceException(typeof(StringConnectionInfo), "CannotInitializeAsReader", ex);
    }
}

我们首先要关注的是：

this.rowsetCtrl = (TraceUtils.CreateInstance("\\Binn\\pfclnt.dll", "Microsoft.SqlServer.Management.Trace.CTraceObjectsRowsetController") as ITraceObjectsRowsetController);

它只是一种加载方式： C：\ Program Files（x86）\ Microsoft SQL Server \ 140 \ Tools \ Binn \ PFCLNT.DLL 归档到内存

如果我们查看PFCLNT.DLL文件，并查找Initialize和InitSource方法，它们不是标准的C＃方法：

// Microsoft.SqlServer.Management.Trace.CTraceObjectsRowsetController
public unsafe void Initialize(ConnectionInfoBase pConnInfo, string pTemplateFileName)
{
    ITraceConnection* ptr = <Module>.CreateOleDbTraceConnection();
    if (null == ptr)
    {
        <Module>.?A0xa0507c21.ProcessError(-2147024882, null);
    }
    CTraceControllerBase.ConvertConnectionInfoToITraceConnection(pConnInfo, ptr);
    ITraceConnection* expr_1D = ptr;
    int num = calli(System.Int32 modopt(System.Runtime.CompilerServices.IsLong) modopt(System.Runtime.CompilerServices.CallConvThiscall)(System.IntPtr), expr_1D, *(*(int*)expr_1D + 12));
    if (num < 0)
    {
        $ArrayType$$$BY0CAA@G $ArrayType$$$BY0CAA@G = 0;
        initblk(ref $ArrayType$$$BY0CAA@G + 2, 0, 1022);
        object arg_50_0 = calli(System.Int32 modopt(System.Runtime.CompilerServices.IsLong) modopt(System.Runtime.CompilerServices.CallConvThiscall)(System.IntPtr,System.UInt16*), ptr, ref $ArrayType$$$BY0CAA@G, *(*(int*)ptr + 180));
        <Module>.?A0xa0507c21.ProcessError(num, (ushort*)(&$ArrayType$$$BY0CAA@G));
    }
    byte b = 0;

    if (num2 < 0)
    {
        $ArrayType$$$BY0CAA@G $ArrayType$$$BY0CAA@G2 = 0;
        initblk(ref $ArrayType$$$BY0CAA@G2 + 2, 0, 1022);
        object arg_9A_0 = calli(System.Int32 modopt(System.Runtime.CompilerServices.IsLong) modopt(System.Runtime.CompilerServices.CallConvThiscall)(System.IntPtr,System.UInt16*), ptr, ref $ArrayType$$$BY0CAA@G2, *(*(int*)ptr + 180));
        <Module>.?A0xa0507c21.ProcessError(num2, (ushort*)(&$ArrayType$$$BY0CAA@G2));
    }
    if (b < 9)
    {
        ITraceConnection* ptr2 = null;
        int num3 = calli(System.Int32 modopt(System.Runtime.CompilerServices.IsLong) modopt(System.Runtime.CompilerServices.CallConvThiscall)(System.IntPtr,ITraceConnection/eConnectionType,ITraceConnection**), ptr, 0, ref ptr2, *(*(int*)ptr + 28));
        if (num3 < 0)
        {
            $ArrayType$$$BY0CAA@G $ArrayType$$$BY0CAA@G3 = 0;
            initblk(ref $ArrayType$$$BY0CAA@G3 + 2, 0, 1022);

            <Module>.?A0xa0507c21.ProcessError(num3, (ushort*)(&$ArrayType$$$BY0CAA@G3));
        }
        ITraceConnection* expr_F1 = ptr;
        object arg_FB_0 = calli(System.UInt32 modopt(System.Runtime.CompilerServices.IsLong) modopt(System.Runtime.CompilerServices.CallConvStdcall)(System.IntPtr), expr_F1, *(*(int*)expr_F1 + 8));
        ptr = ptr2;
        ITraceConnection* expr_101 = ptr2;
        num2 = calli(System.Int32 modopt(System.Runtime.CompilerServices.IsLong) modopt(System.Runtime.CompilerServices.CallConvThiscall)(System.IntPtr), expr_101, *(*(int*)expr_101 + 12));
        if (num2 < 0)
        {
            $ArrayType$$$BY0CAA@G $ArrayType$$$BY0CAA@G4 = 0;
            initblk(ref $ArrayType$$$BY0CAA@G4 + 2, 0, 1022);
            object arg_132_0 = calli(System.Int32 modopt(System.Runtime.CompilerServices.IsLong) modopt(System.Runtime.CompilerServices.CallConvThiscall)(System.IntPtr,System.UInt16*), ptr, ref $ArrayType$$$BY0CAA@G4, *(*(int*)ptr + 180));
            <Module>.?A0xa0507c21.ProcessError(num2, (ushort*)(&$ArrayType$$$BY0CAA@G4));
        }
    }
    this.templateFileName = pTemplateFileName;
    byte* ptr3 = pTemplateFileName;
    if (ptr3 != null)
    {
        ptr3 = RuntimeHelpers.OffsetToStringData + ptr3;
    }
    Char modopt(System.Runtime.CompilerServices.IsConst)& char modopt(System.Runtime.CompilerServices.IsConst)& = ptr3;
    CTraceRowsetCtrl* ptr4 = <Module>.@new(16460u);
    CTraceRowsetCtrl* ptr5;
    try
    {
        if (ptr4 != null)
        {
            ptr5 = <Module>.CTraceRowsetCtrl.{ctor}(ptr4, ptr, char modopt(System.Runtime.CompilerServices.IsConst)&);
        }
        else
        {
            ptr5 = 0;
        }
    }
    catch
    {
        <Module>.delete((void*)ptr4);
        throw;
    }
    this.m_pTraceCtrl = ptr5;
    if (0 == ptr5)
    {
        <Module>.?A0xa0507c21.ProcessError(-2147024882, null);
    }
    ITraceConnection* expr_192 = ptr;
    object arg_19C_0 = calli(System.UInt32 modopt(System.Runtime.CompilerServices.IsLong) modopt(System.Runtime.CompilerServices.CallConvStdcall)(System.IntPtr), expr_192, *(*(int*)expr_192 + 8));
}

因此，由于我对此的知识非常有限，我认为你面对的是一些不在你手中的东西。我相信我们需要在microsoft上找一个人，利用你的网络和SQL社区，让他们看看它失败的原因。
