Definition

Namespace:

System.Workflow.ComponentModel.Design

Assembly:

System.Workflow.ComponentModel.dll

Writes pending changes to the location that the designer was loaded from.

C#

public override void Flush();

Examples

The following example demonstrates how to override the Flush method to serialize a workflow using the WorkflowMarkupSerializer. In this example, the overridden Flush delegates to the PerformFlush method defined in the WorkflowDesignerLoader derived class.

C#

public override void Flush()
{
    this.PerformFlush(null);
}

protected override void PerformFlush(IDesignerSerializationManager manager)
{
    IDesignerHost host = (IDesignerHost)GetService(typeof(IDesignerHost));

    if (host != null && host.RootComponent != null)
    {
        Activity service = host.RootComponent as Activity;

        if (service != null)
        {
            using (XmlWriter writer = XmlWriter.Create(this.xomlFile))
            {
                WorkflowMarkupSerializer xomlSerializer = new WorkflowMarkupSerializer();
                if (manager == null)
                {
                    xomlSerializer.Serialize(writer, service);
                }
                else
                {
                    xomlSerializer.Serialize(manager, writer, service);
                }
            }
        }
    }
}
