Dynamics CRM4.0 和 Dynamics CRM2011 Plugin 实现一样的功能的方法的比较

1.给类型赋值不同

CRM4 plugin给lookup赋值为空 ：

Lookup lookupnull = new Lookup();

lookupnull.IsNull = true;

lookupnull.IsNullSpecified = true;

entity.Properties["new_storeroom_areaid"] = lookupnull;

CRM2011 给 EntityReference 赋值为空：

entity["new_storeroom_areaid"] = null;

2.单表查询,返回Entity

CRM4.0 ：

private DynamicEntity GetNewPrInfo(Guid NewPrID)//根据GUID查询某字段

{

    ColumnSet colSet = new ColumnSet(NewPrInfo.EntityName);

    colSet.AddColumn(NewPrInfo.AttributeName_Assigner);

    colSet.AddColumn(NewPrInfo.AttributeName_AssignNode);

    TargetRetrieveDynamic target = new TargetRetrieveDynamic();

    target.EntityId = NewPrID;

    target.EntityName = NewPrInfo.EntityName;

    RetrieveRequest request = new RetrieveRequest();

    request.ColumnSet = colSet;

    request.ReturnDynamicEntities = true;

    request.Target = target;

    RetrieveResponse response = (RetrieveResponse)this.crmService.Execute(request);

    DynamicEntity PromotionPe = (DynamicEntity)response.BusinessEntity;

    return PromotionPe;

 }

CRM2011:

Entity accEntity = service.Retrieve(“new_test”, new_testid, new ColumnSet("字段1", "字段2"));//根据GUID，查询实体new_test的字段1和字段2的值。

Entity accEntity = service.Retrieve(entityName, entityId, new ColumnSet(true));//根据GUID，查询实体new_test的所有字段。

3.初始化CRM组织服务

CRM4：

CrmAuthenticationToken token = new CrmAuthenticationToken();

token.AuthenticationType = ;

token.OrganizationName = "AdventureWorksCycle";

CrmService service = new CrmService();

service.Url = ""http://<servername>:<port>/mscrmservices/2007/crmservice.asmx";

service.CrmAuthenticationTokenValue = token;

service.Credentials = System.Net.CredentialCache.DefaultCredentials;

CRM2011:

IFD 的服务前面的段必须是https，不分内部和外部。

Uri orgServiceUri = new Uri("https://192.168.1.101/MicrosoftDynamicCRM/XRMServices/2011/Organization.svc");

ClientCredentials credentials = new ClientCredentials();

credentials.UserName.UserName = CRMUserName;

credentials.UserName.Password = CRMUserPassword;

OrganizationServiceProxy crmServiceProxy = new OrganizationServiceProxy(orgServiceUri, null, credentials, null);

crmService = (IOrganizationService)crmServiceProxy;

. on-premise 内部部署（AD认证）,，初始化WebService时的方式如下：

服务前面的段可以是https,也是可以http

如果没有路由映射 外网是访问不了   只能内网访问

Uri organizationUri = new Uri("http://192.168.1.101/MicrosoftDynamicCRM/XRMServices/2011/Organization.svc");

IServiceConfiguration<IOrganizationService> orgConfigInfo = ServiceConfigurationFactory.CreateConfiguration<IOrganizationService>(organizationUri);

var Orgcreds = new ClientCredentials();

Orgcreds.Windows.ClientCredential = new System.Net.NetworkCredential("administrator", "admiN123", "DynamicCRM.com");

OrganizationServiceProxy _serviceproxy = new OrganizationServiceProxy(orgConfigInfo, Orgcreds);

return (IOrganizationService)_serviceproxy;

这样子也可以：

 Uri orgServiceUri = new Uri(Config.CrmWebServiceUrl);

var credentials = new ClientCredentials();

credentials.Windows.ClientCredential = new System.Net.NetworkCredential(Config.CrmServerAccount, Config.CrmServerPSW, Config.CrmServerDomain);

OrganizationServiceProxy _serviceproxy = new OrganizationServiceProxy(orgServiceUri, null, credentials, null);

return (IOrganizationService)_serviceproxy;

4.返回多个实体

CRM4:

// Create a column set holding the names of the columns to be retrieved.

ColumnSet cols = new ColumnSet();

cols.Attributes = new string [] {"name", "accountid"};

// Create the query object.

QueryByAttribute query = new QueryByAttribute();

query.ColumnSet = cols;

query.EntityName = EntityName.account.ToString();

// The query will retrieve all accounts whose address1_city is Sammamish.

query.Attributes = new string [] {"address1_city"};

query.Values = new string [] {"Sammamish"};

// Execute the retrieval.

BusinessEntityCollection retrieved = service.RetrieveMultiple(query);

CRM2011:

方法一：

string fetchxml = @"<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='false' aggregate='true'>

                                  <entity name='new_po_exp_detail'>

                                    <attribute name='new_exp_amount' alias='new_exp_amount_sum' aggregate='sum' />

                                    <attribute name='new_submit_amout' alias='new_submit_amout_sum' aggregate='sum' />

                                    <attribute name='new_expense_category' alias='new_expense_category' groupby='true' />

                                    <filter type='and'>

                                      <condition attribute='statecode' operator='eq' value='0' />

                                    </filter>

                                    <link-entity name='new_po' from='new_poid' to='new_po_exp_detail' alias='ab'>

                                      <filter type='and'>

                                        <condition attribute='statecode' operator='eq' value='0' />

                                        <condition attribute='new_po_status' operator='in'>

                                          <value>5</value>

                                          <value>7</value>

                                        </condition>

                                        <condition attribute='new_promotion_pe' operator='eq'  value='" + new_promotion_peId + @"' />

                                      </filter>

                                    </link-entity>

                                  </entity>

                                 </fetch>";

EntityCollection entitycols = service.RetrieveMultiple(new FetchExpression(fetchxml));

方法二：

QueryByAttribute query = new QueryByAttribute("new_categorytate");

query.ColumnSet = new ColumnSet("new_categorytateid");

query.AddAttributeValue("statecode", );

query.AddAttributeValue("new_sn", new_sn);//产品品类编号

EntityCollection encols = service.RetrieveMultiple(query);
