从 C# 错误中执行 DTS 包无法转换类型为“Microsoft.SqlServer.Dts.Runtime.Wrapper.ApplicationClass”的 COM 对象

问题描述

我正在开发一个控制台应用程序，我正在从 C# 执行 SSIS 包。

下面是我的执行代码

private bool ExecutePackage(int _sid,int _pid,int _envid,string _connection,int _scheduleId)
        {
            bool isSuccess = false;

           try
            {
                var dtPackagePath = HandlerFunctions.GetPackageInformation(_sid,_pid,_envid);
                var DtsxPath = dtPackagePath.Rows[0]["dtsx_path"].ToString();

                Application app = new Application();
                Package package = null;
                //Load the SSIS Package which will be executed
                package = app.LoadPackage(DtsxPath,null);
                //Pass the varibles into SSIS Package

                package.Variables["User::mEnvID"].Value = _envid;
                package.Variables["User::mPID"].Value = _projectid;
                package.Variables["User::mSID"].Value = _sponsorid;
                package.Variables["User::mConnectionString"].Value = _connection;
                
                var results = package.Execute();
                //Check the results for Failure and Success
                if (results == DTSExecResult.Failure)
                {
                    var err = "";
                    foreach (var localDtsError in package.Errors)
                    {
                        var error = localDtsError.Description;
                        err = err + error;
                    }
                }

                if (results == DTSExecResult.Success)
                {
                    isSuccess = true;
                }

            }
            catch (Exception ex)
            {
                isSuccess = false;
                HandlerFunctions.WriteExceptionLog(_scheduleId,_sponsorid,_projectid,"Execute DTSX",ex.Message,ex.InnerException != null ? ex.InnerException.ToString() : string.Empty,ex.StackTrace,Convert.ToDateTime(DateTime.Now));

                throw;
            }
           return isSuccess;
        }

我在这个项目中引用了 Microsoft.Sqlserver.managedDTS.dll 并在 using 属性中使用了以下内容

using Microsoft.SqlServer.Dts.Runtime;
using Application = Microsoft.SqlServer.Dts.Runtime.Application;

我还在系统中使用 GACUTIL 注册了 ManagedDTS.dll。

但是，当我运行 porgram 时，我在 Application app = new Application(); 中遇到错误。错误如下

Unable to cast COM object of type 'Microsoft.SqlServer.Dts.Runtime.Wrapper.ApplicationClass' to interface type 'Microsoft.SqlServer.Dts.Runtime.Wrapper.IDTSApplication130'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{77A93073-6272-4FAC-BDB5-0C589385701C}' failed due to the following error: Library not registered. (Exception from HRESULT: 0x8002801D (TYPE_E_LIBNOTREGISTERED)).

有人能帮我解决这个问题吗？
