我在 Dynamics CRM 中创建自定义操作，添加输入和输出参数，因此情况是，当发送输入时，它将过滤具有该属性的某些实体，并在输出参数中返回实体集合。但问题是它总是会返回状态为 500 内部服务器错误的错误，这是我收到的完整错误

为什么我收到该错误，或者我无法在输出参数上返回 EntityCollection？因为当我返回字符串时它工作正常。

{
context.OutputParameters["BookableResourceBooking"] = new EntityCollection(new List<Entity> { bookableResourceBookingEntity.Entities.FirstOrDefault(), bookableResourceBookingEntity.Entities[0] });

}

我的 postman 请求
organization.crm5.dynamics.com/.../MyActionName
{
"BookableResource" : "{BookableResourceGuid}"
}
最佳答案
假设我有一个名为“Result2”的输出参数。 以下是将输出参数发送到自定义操作的代码-
context.OutputParameters["Result2"] = new EntityCollection(new List<Entity> { entitlements.FirstOrDefault(), order}); //entitlements is List<Entity> object, order is Entity object
对于操作，请确保执行阶段为操作后。 
更新了帖子-
对于 EntityCollection，我们不需要指定目标实体，如下图所示。
这允许我们发送包含单独实体的对象的实体集合。正如您从下图中看到的，我已在单个列表中发送了权利和销售订单实体对象。 
调用操作的脚本如下。我使用 Process.JS 来调用该操作。这是 process.js 的 URL。请将其添加到您必须调用操作的表单中。 GitHub link
function CreateRenewals() {
Xrm.Page.ui.setFormNotification("Please wait, this may take some time..", "INFORMATION", "1");
Process.callAction("gc_CreateRenewalOpportunity",
[{
key: "TargetOrder",
type: Process.Type.EntityReference,
value: new Process.EntityReference("salesorder", Xrm.Page.data.entity.getId())
}],
function (params) {
debugger;//Success
Xrm.Page.ui.clearFormNotification("1");
Xrm.Page.ui.setFormNotification(params.Result, "INFORMATION", "2");
},
function (e, t) {
Xrm.Page.ui.clearFormNotification("1");
Xrm.Page.ui.setFormNotification(params.Result, "INFORMATION", "3");
// Error
});
}
public void Execute(IServiceProvider serviceProvider)
{
ITracingService tracer = (ITracingService)serviceProvider.GetService(typeof(ITracingService));
IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
IOrganizationServiceFactory factory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
IOrganizationService service = factory.CreateOrganizationService(context.UserId);
try
{
Entity entity = null;
if (context.InputParameters.Contains("TargetOrder"))
{
if (context.InputParameters["TargetOrder"] is Entity)
entity = (Entity)context.InputParameters["TargetOrder"];
else if (context.InputParameters["TargetOrder"] is EntityReference)
{
EntityReference entityRef = (EntityReference)context.InputParameters["TargetOrder"];
entity = service.Retrieve(entityRef.LogicalName, entityRef.Id, new Microsoft.Xrm.Sdk.Query.ColumnSet(true));
}
}
context.OutputParameters["Result2"] = new EntityCollection(new List<Entity> { entity });
}
希望有帮助。
关于c# - 在输出参数 CRM 中返回 EntityCollection 时出错，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/53521076/
