Question

我从CRM生成实体：

CrmSvcUtil.exe /url:http://<servername>/<organizationname>/XRMServices/2011/Organization.svc
    /out:<outputfilename>.cs /username:<username> /password:<password> /domain:<domainname>
    /namespace:CRMEntities /serviceContextName:XrmServiceContext

对于 serviceContextName ，我设置 XrmServiceContext 。我想使用下一个代码从CRM中检索一些实体：

var context = new XrmServiceContext(myorgserv);
var marketingList = context.ListSet.Where(item => item.Id == new Guid("SOME GUID"));

我收到错误：

Message "Unable to cast object of type 'Microsoft.Xrm.Sdk.Entity' to type 'CRMEntities.List'."

在'添加到监视'之后，我看到上下文中的每组实体都有相同的消息。我错过了什么？

问题解决了。初始化 OrganizationServiceProxy 后，我必须调用 EnableProxyTypes 方法。

OrganizationServiceProxy orgserv;
ClientCredentials clientCreds = new ClientCredentials();

    clientCreds.Windows.ClientCredential.UserName = username;
    clientCreds.Windows.ClientCredential.Password = password;
    clientCreds.Windows.ClientCredential.Domain = domain;
    IServiceConfiguration<IOrganizationService> orgConfigInfo = ServiceConfigurationFactory.CreateConfiguration<IOrganizationService>(orgServiceUri);

    orgserv = new OrganizationServiceProxy(orgConfigInfo, clientCreds);
    orgserv.EnableProxyTypes();

关键是： orgserv.EnableProxyTypes（）;

CRM检索实体 - 错误：无法将“Microsoft.Xrm.Sdk.Entity”类型的对象强制转换为“CRMEntities.List”
