Eksempel

The following example shows how to use the RetrieveMultiple method. For this sample to work correctly, you must be connected to the server to get an IOrganizationService interface. You can find the complete sample in the sample code package in the folder SampleCode\CS\BusinessDataModel\BusinessManagement\RetrieveOpportunity.cs.

// Retrieve Opportunity record.                
Opportunity checkOpportunity = (Opportunity)_serviceProxy.Retrieve(
    Opportunity.EntityLogicalName,
    _opportunityId,
    new ColumnSet("name"));

Console.WriteLine("Retrieved {0}", checkOpportunity.Name);

// Retrieve the related opportunity products
QueryExpression opportunityProductsQuery = new QueryExpression
{
    EntityName = OpportunityProduct.EntityLogicalName,
    ColumnSet = new ColumnSet("opportunityproductid", "volumediscountamount"),
    Criteria = new FilterExpression
    {
        Conditions = 
    {
        new ConditionExpression 
        {
            AttributeName = "opportunityid",
            Operator = ConditionOperator.Equal,
            Values = { _opportunityId }
        }
    }
    }
};

DataCollection<Entity> opportunityProducts = _serviceProxy.RetrieveMultiple(
    opportunityProductsQuery).Entities;

foreach (Entity entity in opportunityProducts)
{
    OpportunityProduct opportunityProduct = (OpportunityProduct)entity;
    Console.WriteLine("Retrieved Opportunity Product {0}",
        opportunityProduct.OpportunityProductId.Value);
}

The following example shows how to use the RetrieveMultiple method. For this sample to work correctly, you must be connected to the server to get an IOrganizationService interface. You can find the complete sample in the sample code package in the folder SampleCode\CS\BusinessDataModel\Templates\GetEmailTemplateAttachments.cs.

//Create a query to retrieve attachments.
QueryExpression query = new QueryExpression
{
    EntityName = ActivityMimeAttachment.EntityLogicalName,
    ColumnSet = new ColumnSet("filename"),

    //Define the conditions for each attachment.
    Criteria =
    {
        FilterOperator = LogicalOperator.And,
        Conditions =
    {
        //The ObjectTypeCode must be specified, or else the query
        //defaults to "email" instead of "template".
        new ConditionExpression
        {
            AttributeName = "objecttypecode",
            Operator = ConditionOperator.Equal,
            Values = {Template.EntityTypeCode}
        },
        //Specify which template we need.
        new ConditionExpression
        {
            AttributeName = "objectid",
            Operator = ConditionOperator.Equal,
            Values = {_emailTemplateId}
        }
    }
    }
};

//Write out the filename of each attachment retrieved.
foreach (ActivityMimeAttachment attachment in _serviceProxy.RetrieveMultiple(query).Entities)
{
    Console.WriteLine("Retrieved attachment {0}", attachment.FileName);
}

Bemærkninger

Message Availability

Denne meddelelse fungerer, uanset om den kaldende har forbindelse til serveren eller arbejder offline.

Not all entity types support this message offline. See Supported Entities later in this topic.

Privileges and Access Rights

To perform this action, the caller must have privileges on the entity that is specified in the entityName parameter. For a list of the required privileges, see RetrieveMultiple Privileges. This method only returns the records for which the calling user has access rights.

Notes for Callers

The collection of returned records contains the values for the properties that are specified in the ColumnSet parameter for which the calling user has access rights. Any other property values are not returned.

Pass null for the columnSet parameter to retrieve only the primary key. If the columnSet includes attributes that are not valid for retrieval, they are ignored. This is where IsValidForRead is false. Du kan finde disse oplysninger i metadataene for din organisation. Se de forudgående oplysninger om metadata-browseren.

You can use this method to retrieve records of an entity that supports the RetrieveMultiple message, including records from custom entities.

Du kan finde flere oplysninger om the exceptions that can be thrown when this method is called, see Handle Exceptions in Your Code.
