如何在crm 2011中创建和删除多对多实体关系中的数据？

代码：

QueryExpression qry = new QueryExpression();
qry.EntityName = "entity1_entity2";
qry.ColumnSet = new ColumnSet(true);

var re = crmservice.RetrieveMultiple(qry).Entities;


crmservice.Delete("entity1_entity2", re[0].Id);

FaultException：The 'Delete' method does not support entities of type 'entity1_entity2'.

Answer 1

为了通过N：N关系链接两个记录，您必须使用Associate / Disassociate请求或服务代理的相应方法。

这将创建/删除entity1_entity2实体的相应记录。

Answer 2

using Microsoft.Crm.Sdk.Messages;
...
// get the crm service
...
AssociateEntitiesRequest fooToBar = new AssociateEntitiesRequest
{
    Moniker1 = foo,                // foo is an entity reference
    Moniker2 = bar,                // bar is an entity reference
    RelationshipName = "foo_bar",  // name of the relationship
}

service.Execute(fooToBar)          // relates foo and bar

对于删除，请尝试以下

        // Create an AssociateEntities request.
        //Namespace is Microsoft.Crm.Sdk.Messages
        DisassociateEntitiesRequest request = new DisassociateEntitiesRequest();

        // Set the ID of Moniker1 to the ID of the lead.
        request.Moniker1 = new EntityReference
        {
            Id = moniker1.Id,
            LogicalName = moniker1.Name
        };

        // Set the ID of Moniker2 to the ID of the contact.
        request.Moniker2 = new EntityReference
        {
            Id = moniker2.Id,
            LogicalName = moniker2.Name
        };

        // Set the relationship name to associate on.
        request.RelationshipName = strEntityRelationshipName;

        // Execute the request.
        service.Execute(request);

Answer 4

在N：N关系中，记录应该关联和解除关联。您无法在N：N关系中创建和删除记录。您可以使用AssociateRequest，DisassociateRequest类，也可以在插件注册工具中使用Associate，Disassociate Messages。
