示例1: Experiment_For_Filter_Groups
public void Experiment_For_Filter_Groups()
{
// var sql = string.Format("Select C.firstname, C.lastname From contact Where firstname Like '%ax%' ");
var connectionString = ConfigurationManager.ConnectionStrings["CrmOrganisation"];
var serviceProvider = new CrmServiceProvider(new ExplicitConnectionStringProviderWithFallbackToConfig() { OrganisationServiceConnectionString = connectionString.ConnectionString },
new CrmClientCredentialsProvider());
var orgService = serviceProvider.GetOrganisationService();
using (orgService as IDisposable)
{
// var request = new RetrieveMultipleRequest();
var query = new QueryExpression("contact");
// request.Query = query;
query.ColumnSet.AddColumn("firstname");
query.ColumnSet.AddColumn("lastname");
var condition1 = new ConditionExpression("firstname", ConditionOperator.Equal, "Max");
var condition2 = new ConditionExpression("lastname", ConditionOperator.Equal, "Planck");
var filter1 = new FilterExpression(LogicalOperator.And);
filter1.AddCondition(condition1);

foreach (var r in results.Entities)
{
resultCount++;
Console.WriteLine(string.Format("{0} {1}", (string)r["firstname"], (string)r["lastname"]));
}
Console.WriteLine("There were " + resultCount + " results..");
}
}示例2: ToFilterExpression
public static FilterExpression ToFilterExpression(this XElement elem, XrmFakedContext ctx)
{
var filterExpression = new FilterExpression();
filterExpression.FilterOperator = elem.GetAttribute("type").Value.Equals("and") ?
LogicalOperator.And : LogicalOperator.Or;
//Process other filters recursively
var otherFilters = elem
.Elements() //child nodes of this filter
.Where(el => el.Name.LocalName.Equals("filter"))
.Select(el => el.ToFilterExpression(ctx))
.ToList();
//Process conditions
var conditions = elem
.Elements() //child nodes of this filter
.Where(el => el.Name.LocalName.Equals("condition"))
.Select(el => el.ToConditionExpression(ctx))
.ToList();
foreach (var c in conditions)
filterExpression.AddCondition(c);
foreach (var f in otherFilters)
filterExpression.AddFilter(f);
return filterExpression;
