Question

我尝试在script compoment内的ssis中使用我自己的.dll。正常程序给我一个错误："could not load file or assembly 'xxx' or one of its dependencies. The system cannot find the file specified."

我尝试的是我去了项目 - ＆gt;在资源管理器中打开并将我的.dll放入bin文件夹但发生同样的错误。

我找到this C# Code并将其转换为vb.net：

<Microsoft.SqlServer.Dts.Tasks.ScriptTask.SSISScriptTaskEntryPointAttribute> _
Public Partial Class ScriptMain
    Inherits Microsoft.SqlServer.Dts.Tasks.ScriptTask.VSTARTScriptObjectModelBase
    Shared Sub New()
        AppDomain.CurrentDomain.AssemblyResolve += New ResolveEventHandler(AddressOf CurrentDomain_AssemblyResolve)
    End Sub
    Private Shared Function CurrentDomain_AssemblyResolve(sender As Object, args As ResolveEventArgs) As System.Reflection.Assembly
        If args.Name.Contains("ssisHelper") Then
            Dim path As String = "c:\temp\"
            Return System.Reflection.Assembly.LoadFile(System.IO.Path.Combine(path, "ssisHelper.dll"))
        End If
        Return Nothing
    End Function
End Class

但我没有Micorosoft.SqlServer.Dts.**Tasks**。任何可以帮助我的人都可以使这个脚本工作，或者可以提供另一个解决方案让我的dll在script compoment内运行？

您需要通过运行gacutil -i assembly.dll将程序集添加到GAC（全局程序集缓存）

And before adding it to the GAC you need to strong name it, example here: http://microsoft-ssis.blogspot.com/2011/05/referencing-custom-assembly-inside.html

如何让自定义DLL在ssis脚本组件中工作？
