RDLC报表使用方便,能很好镶嵌在web程序里面,且能方便的导出各种文件的格式;使用此报表程序要引用 Microsoft.Reporting.WebForms;下面以一个例子来进行讲解它的用法。

1.后台代码:

 #region 报表

        public ActionResult ReportView()
        {
            return View(ReportModel.ReportModelList);
        }


        public ActionResult DownLoad(string fileType)
        {
            DataTable dt = new DataTable();
            dt.Columns.Add(new DataColumn("ID", typeof(int)));
            dt.Columns.Add(new DataColumn("UserName", typeof(string)));
            dt.Columns.Add(new DataColumn("Address", typeof(string)));
            dt.Columns.Add(new DataColumn("Sex", typeof(string)));
            dt.Columns.Add(new DataColumn("Age", typeof(int)));
            dt.Columns.Add(new DataColumn("Phone", typeof(string)));
            dt.Columns.Add(new DataColumn("IMEID", typeof(string)));
            dt.Columns.Add(new DataColumn("CreateDate", typeof(string)));
            dt.Columns.Add(new DataColumn("HeadImg", typeof(string)));


            List<ReportModel> reportDatas = ReportModel.ReportModelList;

            foreach (var item in reportDatas)
            {
                dt.Rows.Add(item.ID, item.UserName, item.Address, item.Sex ? "" : "", item.Age,
                    item.Phone, item.IMEID, item.CreateDate.ToShortDateString(), getImgStr(item.HeadImg));
            }
             
            LocalReport localReport = new LocalReport();
            localReport.ReportPath = Server.MapPath("~/Report/Report1.rdlc");

            ReportDataSource reportDataSource0 = new ReportDataSource("UserList", dt);
            localReport.DataSources.Add(reportDataSource0);
              
            string reportType = "PDF";
            string mimeType;
            string encoding = "UTF-8";
            string fileNameExtension;

            string deviceInfo = "<DeviceInfo>" + "  <OutputFormat>" + reportType + "</OutputFormat>" + "<PageWidth>21cm</PageWidth>" + "  <PageHeight>29.7cm</PageHeight>" + "  <MarginTop>0.5in</MarginTop>" + "  <MarginLeft>1in</MarginLeft>" + "  <MarginRight>1in</MarginRight>" + "  <MarginBottom>0.5in</MarginBottom>" + "</DeviceInfo>";
            Warning[] warnings;
            string[] streams;
            byte[] renderedBytes;
            string ReportType = string.IsNullOrEmpty(fileType) ? "WORD" : fileType;
            mimeType = "Application/octet-stream";
            renderedBytes = localReport.Render(ReportType, deviceInfo, out mimeType, out encoding, out fileNameExtension, out streams, out warnings);
            string Extension = getFileExtension(ReportType);
            string filename = "OutReport" + Extension;

            return File(renderedBytes, mimeType, filename);
        }

        /// <summary>
        /// 获取报表文件类型
        /// </summary>
        /// <param name="FileName">文件名称,WORD,EXCEL,PDF等</param>
        /// <returns>.doc,.xls,.pdf</returns>
        private string getFileExtension(string FileName)
        {
            string Extension = null;

            if (FileName.Equals("WORD"))
                Extension = ".doc";
            else if (FileName.Equals("PDF"))
                Extension = ".pdf";
            else if (FileName.Equals("EXCEL"))
                Extension = ".xls";

            return Extension;
        }


        public string getImgStr(string imgUrl)
        {
            string imgPath = Server.MapPath(imgUrl);
            Image img = Image.FromFile(imgPath);

            byte[] imgBytes;
            MemoryStream ms = null;
            try
            {
                ms = new MemoryStream();
                img.Save(ms, ImageFormat.Jpeg);
                imgBytes = new Byte[ms.Length];
                imgBytes = ms.ToArray();
            }
            catch (ArgumentNullException ex)
            {
                throw ex;
            }
            finally
            {
                ms.Close();
            }

            string imgString = Convert.ToBase64String(imgBytes);
            return imgString;
        }



        #endregion

 

2.ReportModel 实体的代码如下:

  public class ReportModel
    {
        public int ID { get; set; }
        public string UserName { get; set; }
        public string Address { get; set; }
        public bool Sex { get; set; }
        public int Age { get; set; }
        public string Phone { get; set; }
        public string IMEID { get; set; } 
        public string HeadImg { get; set; }
        public DateTime CreateDate { get; set; }



        public static List<ReportModel> ReportModelList
        {
            get { return ReportModel.getReportModel(); }
        }

        public static List<ReportModel> getReportModel()
        {
            List<ReportModel> rmList = new List<ReportModel>();
            for (int i = 0; i < 10; i++)
            {
                rmList.Add(new ReportModel
                {
                    ID = i + 1,
                    IMEID = "41272719910127456" + i.ToString(),
                    Phone = "1356532458" + i.ToString(),
                    Sex = i % 2 == 1 ? true : false,
                    UserName = "用户" + i.ToString(),
                    CreateDate = DateTime.Now.AddDays(0 - i),
                    Address = "河南省*******",
                    Age = 20 + i,
                     HeadImg="~/Content/Img/headImg.jpg"
                });
            }
            return rmList;
        }
    }

 

 3.前台的代码也很简单,如下:

@{
    ViewBag.Title = "Report";
}
@model IEnumerable<MvcApplication1.Models.ReportModel>
<style type="text/css">
    #UserTable td {
        border-left: 1px solid blue;
        border-bottom: 1px solid blue;
    }

    #UserTable th {
        border-left: 1px solid blue;
        border-bottom: 1px solid blue;
        border-top: 1px solid blue;
    }

        #UserTable th:last-child {
            border-right: 1px solid blue;
        }

    #UserTable td:last-child {
        border-right: 1px solid blue;
    }
</style>
<script type="text/javascript">
    function downLoad(obj) {
        var fileType = $(obj).attr("filetype");
        $("#fileTypeInput").val(fileType);
        $("#downloadForm").submit();
    }
</script>
<form action="/Report/DownLoad" id="downloadForm">
    <input type="hidden" name="fileType" id="fileTypeInput" />
</form>
<table>
    <tr>
        <td filetype="WORD" onclick="downLoad(this)" style="background-image: url(‘../Content/Img/word.png‘); width: 128px; height: 128px; background-repeat: no-repeat; border: 1px solid blue; cursor: pointer;"></td>
        <td filetype="EXCEL" onclick="downLoad(this)" style="background-image: url(‘../Content/Img/excel.png‘); width: 128px; height: 128px; background-repeat: no-repeat; border: 1px solid blue; cursor: pointer;"></td>
        <td filetype="PDF" onclick="downLoad(this)" style="background-image: url(‘../Content/Img/pdf.png‘); width: 128px; height: 128px; background-repeat: no-repeat; border: 1px solid blue; cursor: pointer;"></td>
    </tr>
</table>
<table border="0" cellspacing="0" cellpadding="0" style="width: 100%;" id="UserTable">
    <tr>
        <th>头像</th>
        <th>编号</th>
        <th>用户名称</th>
        <th>年龄</th>
        <th>性别</th>
        <th>地址</th>
        <th>电话</th>
        <th>身份证号</th>
        <th>注册日期</th>
    </tr>
    @foreach (var item in Model)
    { 
        <tr>
            <td>
                <img width="50"  src="@Url.Content(item.HeadImg)"/></td>
            <td>@item.ID</td>
            <td>@item.UserName</td>
            <td>@item.Age</td>
            <td>@(item.Sex ? "" : "")</td>
            <td>@item.Address</td>
            <td>@item.Phone</td>
            <td>@item.IMEID</td>
            <td>@item.CreateDate.ToShortDateString()</td>
        </tr>
    }
</table>

 

 4.实体的数据要传入到一个xsd格式的数据集里面,然后rdlc文件再来访问数据集的数据,数据集如下:

bubuko.com,布布扣

5.rdlc报表文件构建如下:

bubuko.com,布布扣6.

6.有图片的数据,头像的显示方格里面添加一个图片控件,图片控件的value属性值设置如下:

bubuko.com,布布扣

7.页面效果已经导出的Word文件图如下:

bubuko.com,布布扣

bubuko.com,布布扣
