示例1: SerializedAddGeneratedViews
//Collect the names of the entitysetbases and the generated views from
//the generated type into a string so that we can produce a hash over it.
private void SerializedAddGeneratedViews(
MetadataWorkspace workspace, EntityViewContainer viewContainer, Dictionary<EntitySetBase, GeneratedView> extentMappingViews)
{
foreach (var extentView in viewContainer.ExtentViews)
{
EntityContainer entityContainer = null;
EntitySetBase extent = null;
var extentFullName = extentView.Key;
var extentNameIndex = extentFullName.LastIndexOf('.');
if (extentNameIndex != -1)
{
var entityContainerName = extentFullName.Substring(0, extentNameIndex);
var extentName = extentFullName.Substring(extentFullName.LastIndexOf('.') + 1);
if (!workspace.TryGetItem(entityContainerName, DataSpace.CSpace, out entityContainer))
{
workspace.TryGetItem(entityContainerName, DataSpace.SSpace, out entityContainer);
}
if (entityContainer != null)
{

}
}
if (extent == null)
{

//Create a Generated view and cache it
