Question

我在scriptcs中添加了一个应用程序，并添加了一些对版本为v2.0.50727的程序集的引用。因此，在运行scriptcs文件时，它返回为混合模式程序集是针对运行时的版本“v2.0.50727”构建的，无法在4.0运行时加载。app.config中的属性useLegacyV2RuntimeActivationPolicy =“true”可能会解决asp中的问题.net web应用程序。但在scriptcs中它不起作用。进一步搜索显示上面的属性useLegacyV2RuntimeActivationPolicy =“true”应该添加为scriptcs.exe.config。我有一个名为FMUpgrade.csx的应用程序文件，我们如何在FMUpgrade.csx文件中引用此scriptcs.exe.config文件。文档中没有太多关于scriptcs.exe.config的说明。还在app中添加了program.exe.config .config但仍未成功。

Answer 1

经过大量研究后，我得到了解决上述问题的解决方法。通过使用类ExeConfigurationFileMap，我们能够从app.config获取键值，它无法绕过由混合模式汇编错误引起的支持的运行时错误。 Server server = new Server（new ServerConnection（con））; server.ConnectionContext.ExecuteNonQuery（脚本）; 执行语句ExecuteNonQuery时会导致该错误。所以在执行语句之前

if（RuntimePolicyHelper.LegacyV2RuntimeEnabledSuccessfully） server.ConnectionContext.ExecuteNonQuery（脚本）;

解决方案如下使用System.Runtime.CompilerServices; 使用System.Runtime.InteropServices; public static class RuntimePolicyHelper { public static bool LegacyV2RuntimeEnabledSuccessfully {get;私人集; }

    static RuntimePolicyHelper()
    {
        ICLRRuntimeInfo clrRuntimeInfo =
        (ICLRRuntimeInfo)RuntimeEnvironment.GetRuntimeInterfaceAsObject(
        Guid.Empty,
        typeof(ICLRRuntimeInfo).GUID);
        try
        {
            clrRuntimeInfo.BindAsLegacyV2Runtime();
            LegacyV2RuntimeEnabledSuccessfully = true;
        }
        catch (COMException)
        {
            // This occurs with an HRESULT meaning
            // "A different runtime was already bound to the legacy CLR version 2 activation policy."
            LegacyV2RuntimeEnabledSuccessfully = false;
        }
    }

    [ComImport]
    [InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
    [Guid("BD39D1D2-BA2F-486A-89B0-B4B0CB466891")]
    private interface ICLRRuntimeInfo
    {
        void xGetVersionString();
        void xGetRuntimeDirectory();
        void xIsLoaded();
        void xIsLoadable();
        void xLoadErrorString();
        void xLoadLibrary();
        void xGetProcAddress();
        void xGetInterface();
        void xSetDefaultStartupFlags();
        void xGetDefaultStartupFlags();

        [MethodImpl(MethodImplOptions.InternalCall, MethodCodeType = MethodCodeType.Runtime)]
        void BindAsLegacyV2Runtime();
    }
 } using System.Runtime.CompilerServices;

使用System.Runtime.InteropServices; public static class RuntimePolicyHelper { public static bool LegacyV2RuntimeEnabledSuccessfully {get;私人集; }

    static RuntimePolicyHelper()
    {
        ICLRRuntimeInfo clrRuntimeInfo =
        (ICLRRuntimeInfo)RuntimeEnvironment.GetRuntimeInterfaceAsObject(
        Guid.Empty,
        typeof(ICLRRuntimeInfo).GUID);
        try
        {
            clrRuntimeInfo.BindAsLegacyV2Runtime();
            LegacyV2RuntimeEnabledSuccessfully = true;
        }
        catch (COMException)
        {
            // This occurs with an HRESULT meaning
            // "A different runtime was already bound to the legacy CLR version 2 activation policy."
            LegacyV2RuntimeEnabledSuccessfully = false;
        }
    }

    [ComImport]
    [InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
    [Guid("BD39D1D2-BA2F-486A-89B0-B4B0CB466891")]
    private interface ICLRRuntimeInfo
    {
        void xGetVersionString();
        void xGetRuntimeDirectory();
        void xIsLoaded();
        void xIsLoadable();
        void xLoadErrorString();
        void xLoadLibrary();
        void xGetProcAddress();
        void xGetInterface();
        void xSetDefaultStartupFlags();
        void xGetDefaultStartupFlags();

        [MethodImpl(MethodImplOptions.InternalCall, MethodCodeType = MethodCodeType.Runtime)]
        void BindAsLegacyV2Runtime();
    }
 }
