D365 C# - 检索多个并且更新非常慢

Question

我正在构建一个连接到 D365 实例的控制台，使用 fetch XML 查找记录并使用特定值更新这些记录。它有效，它正在更新记录。但是，它每秒只更新大约一两个，这远非理想，我有数十万条记录要更新。我见过/使用过至少每秒更新数百次的控制台应用程序。

我是否以错误的方式去做我想做的事？我的代码中一定有一些东西使它变得非常低效/愚蠢。我还应该说这是我第一次使用 C#，所以我可能正在做一些非常愚蠢的事情。

namespace My.Crm.RetrieveMultipleConsole
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                var connectionString = @"AuthType = Office365; Url = xxxx/;Username=xxxx;Password=xxxx";
                CrmServiceClient conn = new CrmServiceClient(connectionString);

                IOrganizationService service = (IOrganizationService)conn.OrganizationWebProxyClient != null ? (IOrganizationService)conn.OrganizationWebProxyClient : (IOrganizationService)conn.OrganizationServiceProxy;

                string fetchquery = @"<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='false'>
  <entity name='account'>
    <attribute name='name' />

    <filter type='and'>

                var multipleRequest = new Microsoft.Xrm.Sdk.Messages.ExecuteMultipleRequest()

                    Requests = new OrganizationRequestCollection()
                };
                EntityCollection accounts = service.RetrieveMultiple(new FetchExpression(fetchquery));
                foreach (var c in accounts.Entities)
                {

                    Console.WriteLine("accountid: {0}", c.Attributes["name"]);                
                    Microsoft.Xrm.Sdk.Messages.UpdateRequest updateRequest = new Microsoft.Xrm.Sdk.Messages.UpdateRequest { Target = c };
                    multipleRequest.Requests.Add(updateRequest);
                    c.Attributes["name"] = "New Name";
                    Microsoft.Xrm.Sdk.Messages.ExecuteMultipleResponse multipleResponse = (Microsoft.Xrm.Sdk.Messages.ExecuteMultipleResponse)service.Execute(multipleRequest);

                }
            }

            catch (Exception ex)
            {
                Console.WriteLine(ex.ToString());
            }
            Console.ReadLine();
        }
    }

从foreach 循环中取出您的service.Execute(multipleRequest)，将其放在外面。这样执行就真的是ExecuteMultipleRequest了。

var multipleRequest = new Microsoft.Xrm.Sdk.Messages.ExecuteMultipleRequest()
                {
                    Settings = new ExecuteMultipleSettings()
                    {
                        ContinueOnError = false,
                        ReturnResponses = true
                    },
                    Requests = new OrganizationRequestCollection()
                };
                EntityCollection accounts = service.RetrieveMultiple(new FetchExpression(fetchquery));
                foreach (var c in accounts.Entities)
                {

                    Console.WriteLine("accountid: {0}", c.Attributes["name"]);                
                    Microsoft.Xrm.Sdk.Messages.UpdateRequest updateRequest = new Microsoft.Xrm.Sdk.Messages.UpdateRequest { Target = c };
                    multipleRequest.Requests.Add(updateRequest);
                    c.Attributes["name"] = "New Name";

                }

Microsoft.Xrm.Sdk.Messages.ExecuteMultipleResponse multipleResponse = (Microsoft.Xrm.Sdk.Messages.ExecuteMultipleResponse)service.Execute(multipleRequest);
