telerik reporting 在.net core api 使用

工具要求：telerik reporting R3 2019、.net core 2.2  、vs2017 最新版

从官网下载下来的的telerik reporting 的.net core  例子是无法成功预览报表的，可能内部程序有问题，

 以下为正确操作步骤

1.打开nuget 包管理源，新建程序包源（https://nuget.telerik.com/nuget），如下：

 

 

2.切换程序包源，选择telerik reporting  安装包，如下：

 

3.api代码：

 1 namespace CSharp.AspNetCoreDemo.Controllers
 2 {
 3     using System.Collections.Generic;
 4     using System.IO;
 5     using System.Linq;
 6     using Microsoft.AspNetCore.Mvc;
 7     using Telerik.Reporting.Services;
 8     using Telerik.Reporting.Services.AspNetCore;
 9     using System.Net;
10     using System.Net.Mail;
11     using Telerik.Reporting.Cache.File;
12     using Microsoft.AspNetCore.Authorization;

14     [Route("api/reports")]
15     public class ReportsController : ReportsControllerBase
16     {
17         readonly string reportsPath = string.Empty;
18 
19         public ReportsController(ConfigurationService configSvc)
20         {
21              
22             this.reportsPath = Path.Combine(configSvc.Environment.WebRootPath, "report");
23          
24             this.ReportServiceConfiguration = new ReportServiceConfiguration
25             {
26                 ReportingEngineConfiguration = configSvc.Configuration,
27                 HostAppId = "Html5DemoAppCore",
28                 Storage = new FileStorage(),
29                 ReportResolver = new ReportTypeResolver()
30                 .AddFallbackResolver(new ReportFileResolver(this.reportsPath)),
31             };
32         }
33 
34         [HttpGet("reportlist")]
35         public IEnumerable<string> GetReports()
36         {
37             //return Directory

39             //    .Select(path =>
40             //        Path.GetFileName(path));
41 
42 
43             List<string> list = new List<string>();
44 
45             foreach (var item in Directory.GetFiles(this.reportsPath))
46             {
47                 var fileName=  Path.GetFileName(item);
48                 list.Add(fileName);
49             }
50             return list;
51         }
52         protected override HttpStatusCode SendMailMessage(MailMessage mailMessage)
53         {
54             throw new System.NotImplementedException("This method should be implemented in order to send mail messages");
55             //using (var smtpClient = new SmtpClient("smtp01.mycompany.com", 25))
56             //{
57             //    smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;

5. 本人使用的是oracle ，所以是引用Oracle.ManagedDataAccess.Core ，这个dll 不需要按照oracle 的客户端。配置文件添加数据库连接

 

6. 若是想在报表设计器预览 又不想安装oracle 客户端，操作如下：

   1）修改设计器的Telerik.ReportDesigner.exe.config ，在connectionStrings 前添加以下内容

  2）在设计器Telerik.ReportDesigner.exe同级目录放入：

          Oracle.ManagedDataAccess.dll
