如何在 C# 中使用 XRM？

问题描述

您好，我需要将 JS Xrm web api 函数转换为 C#

var opp = Xrm.Page.data.entity.getId();
  Xrm.WebApi.retrieveMultipleRecords(
    "dei_opportunityline","?$select=_dei_vendor_value,dei_multiplier,dei_iscommission,dei_opportunitylineid&$filter=_dei_opportunity_value eq " +
      opp
  ).then(
    function success(result) {
      for (var i = 0; i < result.entities.length; i++) {
        var newMulti = null;
        if (result.entities[i].dei_iscommission) {
          if (
            result.entities[i]["_dei_vendor_value"] ==
            "5fc8d03b-c41c-eb11-a813-000d3a31ed8d"
          ) {
            if (jcimulti != null) newMulti = jcimulti;
          } else {
            if (commulti != null) newMulti = commulti;
          }

对于 .retrieveMultipleRecords、result.entities[i].dei_iscomission 等方法

有没有办法在 C# 插件中编写这个？！

解决方法

您不能在 C# 中使用 Xrm，这仅在 Dynamics 客户端脚本 (JS) 上下文中有用。即网络表单上下文。

对于服务器端 (C#)，您必须使用 HttpClient。 Sample code

        HttpClient httpClient = null;
        httpClient = new HttpClient();
        //Default Request Headers needed to be added in the HttpClient Object
        httpClient.DefaultRequestHeaders.Add("OData-MaxVersion","4.0");
        httpClient.DefaultRequestHeaders.Add("OData-Version","4.0");
        httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

        //Set the Authorization header with the Access Token received specifying the Credentials
        httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer",authToken);

        httpClient.BaseAddress = new Uri("https://yourorg.api.crmx.dynamics.com/api/data/v9.0/");
        var response = httpClient.GetAsync("dei_opportunityline?$select=_dei_vendor_value,dei_multiplier,dei_iscommission,dei_opportunitylineid&$filter=_dei_opportunity_value eq <guid>").Result;
        if (response.IsSuccessStatusCode)
        {
            var records = response.Content.ReadAsStringAsync().Result;

            //you can get dei_iscomission from above records  
        }

这是我们在控制台应用程序中使用的方式，但在插件或工作流代码中 - 您可以使用 Org Service 使用查询表达式或 fetchxml 获取数据。 service.RetrieveMultiple 之类的方法将满足您的需求。 Read more
