Question

我正在使用动态365的在线实例。我创建了C＃Web API以从活动实体导出数据。当我从visual studio运行时，它工作正常。

现在我想在Dynamics 365中点击按钮调用它。要求是当用户点击按钮时，应调用Web API并导出数据。我不知道如何完成这项任务。任何人都可以帮我解决这个问题。请为我提供完成此任务的步骤。 Web API代码如下所示

using System;
using System.Collections.Generic;
using System.Configuration;
using System.IO;
using System.Linq;
using System.ServiceModel;
using Microsoft.Crm.Sdk.Messages;
using Microsoft.Xrm.Client;
using Microsoft.Xrm.Client.Services;
using Microsoft.Xrm.Sdk;
using System.Windows.Forms;

namespace Experiments
{
    class Program
    {
        private static OrganizationService _orgService;
        static void Main(string[] args)
        {
            try
            {
                CrmConnection connection = CrmConnection.Parse(ConfigurationManager.ConnectionStrings["CrmOnline"].ConnectionString);

                using (_orgService = new OrganizationService(connection))
                {

                    var exportToExcelRequest = new OrganizationRequest("ExportToExcel");
                    exportToExcelRequest.Parameters = new ParameterCollection();
                    //Has to be a savedquery aka "System View" or userquery aka "Saved View" 
                    //The view has to exist, otherwise will error out
                    exportToExcelRequest.Parameters.Add(new KeyValuePair<string, object>("View", new EntityReference("savedquery", new Guid("{00000000-0000-0000-00AA-000010001902}"))));
                    exportToExcelRequest.Parameters.Add(new KeyValuePair<string, object>("FetchXml", @"<?xml version='1.0'?>

Answer 1

我建议您将C＃代码编译为Action，并将其作为工作流程中的一个步骤包含在内。有关如何从工作流程调用自定义操作的信息，请参阅here。

我建议您安装Ribbon Workbench。这将允许您自定义表单和导航以添加一个或多个按钮。您可以使用工作台自定义这些按钮，设置其命令以调用您的工作流，然后调用您的Action（您的C＃代码）。

请注意，有几种解决方案可以实现您的要求，我只是提出了一个解决方案。其他解决方案可能包括JavaScript并调用Web API客户端。

由于您在线使用Dynamics 365，因此我建议您创建带有CDS连接器的Microsoft FLOW应用程序。希望这可以帮助。
