如何使用控制台应用程序从 Dynamics CRM Online 检索数据？

Question

我是 Dynamics CRM 的新手，我想创建一个控制台应用程序，它可以为帐户实体创建新记录，并可以显示来自 Dynamics CRM 在线帐户实体的所有帐户名称的列表。

这是我的代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Configuration;
using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Tooling.Connector;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            int choice;
            CrmServiceClient crmConn = new CrmServiceClient(ConfigurationManager.ConnectionStrings["CRM"].ConnectionString);
            IOrganizationService crmService = crmConn.OrganizationServiceProxy;

            Entity acc = new Entity("account");
            String account_name;
            Console.WriteLine("Press 1 to Create a new account or Press 2 to view list of available accounts.");
            choice = Convert.ToInt32(Console.ReadLine());
            switch (choice)
            {
                case 1:
                    Console.WriteLine("Enter Name of Account to Create ?");
                    account_name = Console.ReadLine();
                    acc["name"] = account_name;
                    crmService.Create(acc);
                    Console.WriteLine("*****An account with name {0} is created successfully*****", account_name);
                    Console.WriteLine();
                    Console.WriteLine("Press any key to exit..");
                    Console.ReadKey();
                    break;
                case 2:
                    //code to display list of all account names in CRM.
                    Console.ReadKey();
                    break;
                default:
                    Console.WriteLine("Wrong input...");
                    Console.ReadKey();
                    break;

            }
        }

    }
}

Answer 1

这是我的答案

Inside Case 2：我使用了以下代码：

QueryExpression query = new QueryExpression { EntityName = "account", ColumnSet = new ColumnSet(new string[] { "name" }) };
EntityCollection account = crmService.RetrieveMultiple(query);
string name = "";
foreach (var count in account.Entities)
{
    name = count.GetAttributeValue<string>("name");
    Console.WriteLine(name);
}
Console.ReadKey();

Answer 2

对于案例 2，我最好采用使用 FetchXML 的方法。转到高级查找并获取您的过滤条件，然后下载 xml 文件。

然后将 fetchxml 合并到您的代码中并像这样检索数据

var objCollection = crmService.RetrieveMultiple(new FetchExpression(fetchXMLString));

希望对你有帮助
