Well, I have this command: IOrganizationService.Retrieve(String entityName, Guid ID, ColumnSet columnSet)
reference: IOrganizationService
I tried the SDK Code Samples but the retrieve information is made using the Guid when this create a record, like here: Guid _accountId = orgService.Create(account);
I want to get this Guid
using the name of the Account(Entity), how can I do that?
You have to use RetrieveMultiple
method & QueryExpression
to achieve it. For example, the below MSDN code example is self explained to get the contact(s) with lastname = “Brown”
// Query using ConditionExpression and FilterExpression
ConditionExpression condition1 = new ConditionExpression();
condition1.AttributeName = "lastname";
condition1.Operator = ConditionOperator.Equal;
condition1.Values.Add("Brown");
FilterExpression filter1 = new FilterExpression();
filter1.Conditions.Add(condition1);
QueryExpression query = new QueryExpression("contact");
query.ColumnSet.AddColumns("firstname", "lastname");
query.Criteria.AddFilter(filter1);
EntityCollection result1 = _serviceProxy.RetrieveMultiple(query);
Console.WriteLine();Console.WriteLine("Query using Query Expression with ConditionExpression and FilterExpression");
Console.WriteLine("---------------------------------------");
foreach (var a in result1.Entities)
{
Console.WriteLine("Name: " + a.Attributes["firstname"] + " " + a.Attributes["lastname"]);
}
Query expressions are used in methods that retrieve more than one record, such as the IOrganizationService.RetrieveMultiple method, in messages that perform an operation on a result set specified by a query expression, such as BulkDeleteRequest and when the ID for a specific record is not known.
