An integer specifying how many events have been submitted in this LoadXml call.

Notas

This method can take an object of any of the classes that inherit from the Stream class as its input parameter. However, not all of these classes are truly applicable. The classes that are compatible with this method are:

The Stream class itself is abstract, which means that it cannot be used directly. Instead, it serves as a base class from which other classes can be derived.

Ejemplo

The following examples show how to use the LoadXml method to submit XML event data from a Stream object to the application database:

Dim instanceName As String = "MyInstanceName"
Dim applicationName As String = "MyApplicationName"
Dim eventClassName As String = "MyEventClassName"
Dim eventProviderName As String = "MyEventProviderName"
Dim eventSchema As String = "MySchemaFilePathAndName"
Dim myXmlFile As String = "MyXMLFilePathAndName"

'Create an NSInstance object.
Dim myInstance As New NSInstance(instanceName)

'Create an NSApplication object.
Dim myApplication As New NSApplication(myInstance, applicationName)

'Create an EventLoader object.
Dim myEventLoader As New EventLoader(myApplication, _
    eventProviderName, eventClassName, eventSchema)

'Use the LoadXml method to load an XML document.
Dim myStream As New System.IO.FileStream(myXmlFile, _
    System.IO.FileMode.Open)
Dim eventsWritten As Integer = myEventLoader.LoadXml(myStream)

string instanceName = "MyInstanceName";
string applicationName = "MyApplicationName";
string eventClassName = "MyEventClassName";
string eventProviderName = "MyEventProviderName";
string eventSchema = "MySchemaFilePathAndName";
string myXmlFile = "MyXMLFilePathAndName";

//Create an NSInstance object.
NSInstance myInstance = new NSInstance(instanceName);

//Create an NSApplication object.
NSApplication myApplication = 
    new NSApplication(myInstance, applicationName);

//Create an EventLoader object.
EventLoader myEventLoader = 
    new EventLoader(myApplication, eventProviderName, 
    eventClassName, eventSchema);

//Use the LoadXml method to load an XML document.
System.IO.FileStream myStream = 
    new System.IO.FileStream(myXmlFile, 
    System.IO.FileMode.Open);
int eventsWritten = myEventLoader.LoadXml(myStream);
