Question

我在尝试打开自定义控件流组件的编辑器时遇到了问题。我试图复制包所在的dll但没有帮助。如果我做错了什么或如何解决这个问题，请告诉我。

Here is the code:
Main class inherits TASK                         

namespace SSIS.Custom.ControlFlowUI

       TaskType = "CustomComponent",
       UITypeName = "CopyTableTaskUI, CopyTable, Version=1.0.0.0,Culture=Neutral, PublicKeyToken=9097a336d1055e0b")]

    public class CopyTable : Task
    {
         #region Override methods

            public override DTSExecResult Validate(Connections connections,
            VariableDispenser variableDispenser, IDTSComponentEvents componentEvents,
            IDTSLogging log)
            {
                return base.Validate(connections, variableDispenser, componentEvents, log);
            }

            public override DTSExecResult Execute(Connections connections, VariableDispenser variableDispenser, IDTSComponentEvents componentEvents, IDTSLogging log, object transaction)
            {
                try
                {
                    ValidateSchema(@"GGN19\MSSQL12");

                    //   Return success.
                    return DTSExecResult.Success;
                }
                catch (System.Exception exception)
                {
                    //   Capture exceptions, post an error, and fail validation.

                    return DTSExecResult.Failure;

错误与附加到自定义控制流的用户界面有关，它基本上可以创建2种类型的控制流组件，一种是简单转换，另一种你也可以有一些UI来获取用户输入，ssis将允许你双击组件并提供值...所以当我双击com以获取UI时它的抛出错误。标题：Microsoft Visual 无法显示此任务的编辑器。无法加载由类型名称“CopyTableTaskUI，CopyTable，Version = 1.0.0.0，Culture = Neutral，PublicKeyToken = 9097a336d1055e0b”指定的任务用户界面。无法加载文件或程序集'CopyTable，Version = 1.0.0.0，Culture = neutral，PublicKeyToken = 9097a336d1055e0b'或其依赖项之一。

我遇到类似的问题，错误“无法加载类型：”后跟“验证组件编辑器是否已正确安装。”。当我在客户端计算机中部署我的dll时出现了问题，并且在创建后在第二个会话中重新编辑DTSX包后出现了问题。自定义UI将不会显示。

我通过将自定义dll复制到Visual Studio所在的文件夹（devenv.exe）来解决此问题。这个VS是一个shell版本，适合创建DTSX包而不是其他。

在GAC中安装我的DLL没有帮助。我必须提一下，我的包没有签名，但我使用“reg file / Merge”运行异常无济于事。

在ssis 2012中加载自定义控制流组件的编辑器时出错
