如何在C#中使用XRM？

Question

你好，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;
          }

对于像.retrieveMultipleRecords、result.entitiesi.dei_iscomission这样的方法

有没有办法用C#插件来写这个?！

您不能在C#中使用Xrm，这只在动态客户端脚本(JS)上下文中有用。ie web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通过查询表达式或fetchxml来获取数据。像service.RetrieveMultiple这样的方法将满足您的需要。Read more

只需在C#中包含crmsdk nuget包即可。然后你就可以随心所欲地连接了。请参阅docs
