示例1: ProjectAttributes
public static Entity ProjectAttributes(this Entity e, QueryExpression qe, XrmFakedContext context)
{
if (qe.ColumnSet == null) return e;
if (qe.ColumnSet.AllColumns)
{
return e; //return all the original attributes
}
else
{
//Return selected list of attributes in a projected entity
Entity projected = null;
//However, if we are using proxy types, we must create a instance of the appropiate class
if (context.ProxyTypesAssembly != null)
{
var subClassType = context.FindReflectedType(e.LogicalName);
if (subClassType != null)
{
var instance = Activator.CreateInstance(subClassType);

else

}
else

foreach (var attKey in qe.ColumnSet.Columns)
{
//Check if attribute really exists in metadata

public static Entity JoinAttributes(this Entity e, IEnumerable<Entity> otherEntities, ColumnSet columnSet, string alias, XrmFakedContext context)
{
foreach (var otherEntity in otherEntities) {
var otherClonedEntity = otherEntity.Clone(); //To avoid joining entities from/to the same entities, which would cause collection modified exceptions
if (columnSet.AllColumns)
