SSIS 如何在脚本任务中执行 dll（未找到 SharePoint 函数）

Question

我无法在 SSIS 脚本任务中使用特定的 DLL。在 c# 控制台项目中，一切都很好。 SSIS 抛出错误：

Error: The Type "Microsoft.SharePoint.Client.ClientRuntimeContext" in assembly "Microsoft.SharePoint.Client, Version=14.0.0.0, Culture=neutral PublicKeyToken=...." could not be loaded.

我运行 Visual Studio 2017 年使用 Datatools。我从 NuGet-paket-manager 获取库并将它们保存在本地 C:/

Microsoft.SharePoint.Client，版本 14.0.0.0，运行时版本 v2.0.50727
Microsoft.SharePoint.Client.运行时，版本 15.0.0.0，运行时版本 v4.0.30319

我的控制台项目是 .NET 4.6，我也将 SSIS 项目设置为 .NET 4.6。在这两种情况下，我都通过右键单击 References > Add > Search from computer

添加了库

我刚刚测试了一个控制台项目没有任何问题:


static void Main(string[] args)
{
    using (ClientContext clientContext = new ClientContext("urltomysite.com"))
    {
    }
    Console.WriteLine("finished");
}

这是 SSIS 中的代码（类似...只是使用对象 ClientContext:


public void Main()
{
    //Loading assemblies extra
    AppDomain.CurrentDomain.AssemblyResolve += new ResolveEventHandler(CurrentDomain_AssemblyResolve);
    AppDomain.CurrentDomain.AssemblyResolve += new ResolveEventHandler(CurrentDomain_AssemblyResolve2);

    try
    {
        //Testing the assembly method
        Class1.TESTIT();
    }
    catch (Exception ex)
    {
        Dts.Events.FireError(0, "Error", ex.Message, null, 0);
        Dts.TaskResult = (int)ScriptResults.Failure;
    }

}

static System.Reflection.Assembly CurrentDomain_AssemblyResolve(object sender, ResolveEventArgs args)
{
        return System.Reflection.Assembly.LoadFile(System.IO.Path.Combine("C:/", "Microsoft.SharePoint.Client.dll"));
}

static System.Reflection.Assembly CurrentDomain_AssemblyResolve2(object sender, ResolveEventArgs args)
{
        return System.Reflection.Assembly.LoadFile(System.IO.Path.Combine("C:/", "Microsoft.SharePoint.Client.Runtime.dll"));
}

class Class1
{
    public static void TESTIT()
    {
        using (ClientContext clientContext = new ClientContext("urltomysite.com"))
        {
        }
    }
}

终于找到错误了...

我必须先加载

Microsoft.SharePoint.Client.Runtime.dll

然后我不得不加载另一个库

Microsoft.SharePoint.Client.dll

所以在 Main 中我切换了 library-loading:

AppDomain.CurrentDomain.AssemblyResolve += new ResolveEventHandler(CurrentDomain_AssemblyResolve2);
AppDomain.CurrentDomain.AssemblyResolve += new ResolveEventHandler(CurrentDomain_AssemblyResolve);
