控制台程序实现利用CRM组织服务和SqlConnection对数据库中数据的增删改查操作

一、首先新建一个控制台程序。命名为TestCol。

二、打开App.config在里面加入，数据库和CRM连接字符串

<connectionStrings>
<add name="SqlServerConnString" connectionString="server=IP地址;database=数据库名称;uid=sa;pwd=密码"/>
<add name="CrmConnnectionString" connectionString="Url=http://IP地址/组织名;Username=用户名;Password=密码;Domain=域;"/>
</connectionStrings>

三、打开Program.cs写代码。主要代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data.SqlClient;
using Microsoft.Xrm.Client;//
using System.Data;
using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Query;
using System.Xml;
using System.IO;
using System.Configuration;
using System.Threading.Tasks;

namespace TestCol
{
    public class Program
    {
        static string CRMConnectionPath = string.Empty;  // CRM连接字符串
        static SqlConnection sqlConnection = new SqlConnection();  // 中间库连接字符串
        static void Main(string[] args)
        {
            InitializeConfig();//初始化链接
            CrmConnection connection = CrmConnection.Parse(CRMConnectionPath);
            using (CrmOrganizationServiceContext orgservice = new CrmOrganizationServiceContext(connection))
            {
                 getNew_categorytate(orgservice);
            }
        }

        //逻辑方法
        protected static void getNew_categorytate(IOrganizationService service)
        {
            string sqlstr = "select * from Check_Buget_Sumtable where new_message1=0";//所有未同步的数据
            DataTable dt = new DataTable();
            SQLExecuteData(sqlstr, sqlConnection,dt);
            for (int i = ; i < dt.Rows.Count; i++)
            {
                string New_buget_name = !string.IsNullOrEmpty(dt.Rows[i]["New_buget_name"].ToString()) ? dt.Rows[i]["New_buget_name"].ToString() : string.Empty;//预算费用项名称

                decimal new_usabled_buget = Convert.ToDecimal(dt.Rows[i]["new_usabled_buget"].ToString());//预计全年可用预算
                decimal new_sum_buget = Convert.ToDecimal(dt.Rows[i]["new_sum_buget"].ToString());//累计实现预算
                string new_message1 = !string.IsNullOrEmpty(dt.Rows[i]["new_message1"].ToString()) ? dt.Rows[i]["new_message1"].ToString() : "";

                EntityCollection encols = getBuget(service, New_buget_name);

                          foreach (Entity item1 in encol.Entities)
                          {
