Question

我正在创建一个将平均分配折扣的插件。我想平均分配所有产品的折扣金额。因此，如果一个产品的价格为2000，而另一个产品的价格为1000，则我想给予折扣300，因此应将其除以金额200应分配为2000，crm为100至100。 / p>

public class DivideEqualDiscount : IPlugin

{
    static IOrganizationService _service;
    public void Execute(IServiceProvider serviceProvider)
    {


        IPluginExecutionContext context = (IPluginExecutionContext)
        serviceProvider.GetService(typeof(IPluginExecutionContext));

        ITracingService tracingService =


    (ITracingService)serviceProvider.GetService(typeof(ITracingService));

        if (context.InputParameters.Contains("Target") &&
            context.InputParameters["Target"] is Entity)
        {
            Entity target = (Entity)context.InputParameters["Target"];

            if (target.Attributes.Contains("new_amount"))
            {
                target["new_amount"] = "52";

            {
                target["new_discount"] = "52";
            }


            string fetchData = @"

一种方法是计算折扣与商机总额的百分比，然后将该折扣百分比应用于每行。

例如：

using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Client;
using Microsoft.Xrm.Tooling.Connector;
using System;
using System.Collections.Generic;
using System.Linq;

public override void Run()
{            
    var totalDiscount = 200000;
    using (var ctx = new OrganizationServiceContext(svc))
    {
        var q = from l in ctx.CreateQuery("opportunityproduct")
                where l.GetAttributeValue<EntityReference>("opportunityid").Id.Equals(new Guid("D80E0283-5BF2-E311-945F-6C3BE5A8DD64"))                             
                select l;
        var lines = q.ToList();

        var total = lines.Sum(l => getLineTotal(l));
        var discountPercent = totalDiscount / total;

        lines.ForEach(l =>
        {
            var discount = discountPercent * getLineTotal(l);
            l["manualdiscountamount"] = new Money(discount);
            ctx.UpdateObject(l);
        });
        ctx.SaveChanges();
    }
}

private decimal getLineTotal(Entity line) => 
    line.GetAttributeValue<Money>("priceperunit").Value * line.GetAttributeValue<decimal>("quantity");
