Package.SaveToXML Method (String%, IDTSEvents)
Saves the package to memory in an XML format. To save a package as .xml to the hard drive, use the Application.SaveToXml method.
Namespace: Microsoft.SqlServer.Dts.Runtime
Assembly: Microsoft.SqlServer.ManagedDTS (in Microsoft.SqlServer.ManagedDTS.dll)
Syntax
'Declaration
Public Sub SaveToXML ( _
<OutAttribute> ByRef packageXml As String, _
events As IDTSEvents _
)
'Usage
Dim instance As Package
Dim packageXml As String
Dim events As IDTSEvents
instance.SaveToXML(packageXml, events)
public void SaveToXML(
out string packageXml,
IDTSEvents events
)
public:
void SaveToXML(
[OutAttribute] String^% packageXml,
IDTSEvents^ events
)
member SaveToXML :
packageXml:string byref *
events:IDTSEvents -> unit
public function SaveToXML(
packageXml : String,
events : IDTSEvents
)
Parameters
- packageXml
Type: System.String%
An out parameter that contains the XML that is created when the package is saved.
- events
Type: Microsoft.SqlServer.Dts.Runtime.IDTSEvents
An object that implements the events to raise errors, warnings, or informational events.
Remarks
If you want to save a package as XML to the hard drive, use the Application.SaveToXml method. If you want to save the package to the File System, use Application.SaveToDtsServer. If you want to save the package to the MSDB database, use Application.SaveToSqlServer or Application.SaveToSqlServerAs methods. When you call the Application.SaveToXml methods on the Application, the runtime will iterate through the tasks, connection managers, log providers, and all other objects that are contained by the package and call the SaveToXML method on each of them. The contained objects have code in their SaveToXML that creates an XmlElement for each property that the object must save, and a value for the element. The package contains the XmlDocument and the objects append their specific elements into the package’s XmlDocument. Therefore, you do not directly call the SaveToXML on the individual objects, but call the method on the Application object, and the runtime will cascade through the package objects and call the SaveToXML for you.
Examples
The following code example creates a package and sets several package properties. The package is then saved to an in-memory XmlDocument using the SaveToXML method. Next, a new task is added to the package. The final task of the code example is to save the entire XML to a file on the hard-drive using SaveToXml.
