示例
The following example shows how to use this message. For this sample to work correctly, you must be connected to the server to get an IOrganizationService接口。有关完整示例,请参阅本主题后面的链接。
This sample shows how to change the order of options in a local option set. The following sample retrieves a custom PicklistAttributeMetadata attribute and changes the order of the original options using the OrderBy LINQ function to sort items in ascending order by the label text. Then it uses OrderOptionRequest to set the new order of the options for the attribute.
Use the OrderByDecending LINQ function to order the items in descending order.
// Use the RetrieveAttributeRequest message to retrieve
// a attribute by it's logical name.
RetrieveAttributeRequest retrieveAttributeRequest =
new RetrieveAttributeRequest
{
EntityLogicalName = Contact.EntityLogicalName,
LogicalName = "new_picklist",
RetrieveAsIfPublished = true
};
// Execute the request.
RetrieveAttributeResponse retrieveAttributeResponse =
(RetrieveAttributeResponse)_serviceProxy.Execute(
retrieveAttributeRequest);
// Access the retrieved attribute.
PicklistAttributeMetadata retrievedPicklistAttributeMetadata =
(PicklistAttributeMetadata)
retrieveAttributeResponse.AttributeMetadata;
// Get the current options list for the retrieved attribute.
OptionMetadata[] optionList =
retrievedPicklistAttributeMetadata.OptionSet.Options.ToArray();
// Change the order of the original option's list.
// Use the OrderBy (OrderByDescending) linq function to sort options in
// ascending (descending) order according to label text.
// For ascending order use this:
var updateOptionList =
optionList.OrderBy(x => x.Label.LocalizedLabels[0].Label).ToList();
// For descending order use this:
// var updateOptionList =
// optionList.OrderByDescending(
// x => x.Label.LocalizedLabels[0].Label).ToList();
// Create the request.
OrderOptionRequest orderOptionRequest = new OrderOptionRequest
{
// Set the properties for the request.
AttributeLogicalName = "new_picklist",
EntityLogicalName = Contact.EntityLogicalName,
// Set the changed order using Select linq function
// to get only values in an array from the changed option list.
Values = updateOptionList.Select(x => x.Value.Value).ToArray()
};
// Execute the request
_serviceProxy.Execute(orderOptionRequest);
Console.WriteLine("Option Set option order changed");
