使用插件创建的实体没有有效的 Entity.Id 值

Question

我成功地执行了创建实体的语句，没有任何错误，但是实体的 id 仍然是默认值 00000000-0000-0000-0000-000000000000。在CRM中，创建的实体也没有出现。

我没有在实体中包含所有字段，只输入了1个字段进行测试。

是否由于某些必填字段未填写，导致上述实体创建误报？

下面是我的代码片段：

调用 CreateCase(行)

foreach (DataRow row in caseTable.Rows)
{
    Entity caseEntity = helper.GetCasebyID((string)row[Excel.ID]);

    if (caseEntity == null)
    {
        caseEntity = CreateCase(row);
    }
}

创建案例（行）：

private Entity CreateCase(DataRow row)
{
    Entity caseEntity = new Entity("new_case");

    if (!(string.IsNullOrEmpty(row[Excel.sourcename].ToString().Trim())))
    {
        caseEntity.Attributes[Case.sourcename] = row[Excel.sourcename];
    }
    helper.GetOrganizationService().Create(caseEntity);
    Logger.Info(caseEntity.LogicalName + " " + caseEntity.Id + " created. ");
    //output: case 00000000-0000-0000-0000-000000000000 created. 
}

帮手class:

public class Helper
{
    private OrganizationServiceProxy _proxy;
    private IOrganizationService _org;

    public IOrganizationService GetOrganizationService()
    {
        if (_org == null)
        {
            var credential = new ClientCredentials();
            credential.Windows.ClientCredential.Domain = ConfigurationManager.AppSettings["Domain"];
            credential.Windows.ClientCredential.UserName = ConfigurationManager.AppSettings["Username"];
            credential.Windows.ClientCredential.Password = Decrypt(ConfigurationManager.AppSettings["Password"]);
            Uri organizationUri = new Uri(ConfigurationManager.AppSettings["OrganizationUri"]);
            Uri homeRealmUri = null;
            _proxy = new OrganizationServiceProxy(organizationUri, homeRealmUri, credential, null);
            _proxy.ServiceConfiguration.CurrentServiceEndpoint.Behaviors.Add(new ProxyTypesBehavior());
            _org = new OrganizationService(_proxy);
        }
        return _org;
    }
}

您不应使用同一个对象来检查创建的记录或 guid 是否可用。在你的代码下面一行 return Guid 数据类型而不是对象的子集。

helper.GetOrganizationService().Create(caseEntity);

另外，当您创建记录时，请尝试至少添加主名称属性值。在你的情况下，它应该是 new_name

所以你的代码应该是

Guid newlyCreatedCaseRecord = helper.GetOrganizationService().Create(caseEntity);
 Logger.Info(caseEntity.LogicalName + " " + newlyCreatedCaseRecord  + " created. ");

您还可以从数据库中获取新创建的记录作为实体对象。

    Guid newlyCreatedCaseRecord = helper.GetOrganizationService().Create(caseEntity);
        Entity newlyCaseEntity = helper.GetOrganizationService().Retrieve("new_case",newlyCreatedCaseRecord , new ColumnSet(true));
Logger.Info(newlyCaseEntity .LogicalName + " " + newlyCaseEntity.Id + " created. ");

注意：代码中可能有错别字，请尝试在Visual studio中验证。
