Executing SSIS package from c#

I have to create a Windows Form application which would modify the connection sring values present in dts config file and then execute the package with this updated dts config file.

Even if I am adding following line of code,it is not taking the updated confi开发者_JAVA百科g file.

string packagePath = ConfigurationSettings.AppSettings["packagepath"].ToString();
Microsoft.SqlServer.Dts.Runtime.Application app = new Microsoft.SqlServer.Dts.Runtime.Application();
 Package package = app.LoadPackage(packagePath, null);
 package.ImportConfigurationFile(configPath);
 DTSExecResult dtsResult = package.Execute();

Please help how to execute the package with modified dts config.

You need to read the dtsConfig file, which is an XML file, using the .NET XMLDocument object and then modify the appropriate node containing the connection string with the new value.

Example in the following MSDN forum shows how this can be done:

Setting SSIS package properties programmatically

Personally, I use database table to store package configuration values. I feel that is much easier to maintain than the xml configuration files (dtsconfig).
