基础教程之导出Pdf收据

说明

本教程主要说明如何使用Magicodes.IE.Pdf完成Pdf收据导出

要点

导出PDF数据
自定义PDF模板
导出单据
如何批量导出单据

导出特性

PdfExporterAttribute

Orientation：方向(横向或纵向)
PaperKind：纸张类型（默认A4）
IsWriteHtml：是否输出HTML模板

ExporterHeaderAttribute

DisplayName：显示名称

主要步骤

1.安装包Magicodes.IE.Pdf

Install-Package Magicodes.IE.Pdf

2.导出PDF数据

创建Dto类

        public class Student
        {
            /// <summary>
            ///     姓名
            /// </summary>
            public string Name { get; set; }
            /// <summary>
            ///     年龄
            /// </summary>
            public int Age { get; set; }
        }

       public async Task ExportPdf()
        {
            var exporter = new PdfExporter();
            var result = await exporter.ExportListByTemplate("test.pdf", new List<Student>()
            {
                new Student
                {
                    Name = "MR.A",
                    Age = 18
                },
                new Student
                {
                    Name = "MR.B",
                    Age = 19
                },
                new Student
                {
                    Name = "MR.B",
                    Age = 20
                }
            });
        }

导出内容如下所示：

通过上述代码我们实现了一个简单的Pdf文件导出，也许这样无法达到我们的要求，我们需要自定义标题，那么请看如下代码

        [PdfExporter(Name = "学生信息")]
        public class Student
        {
            /// <summary>
            ///     姓名
            /// </summary>
            [ExporterHeader(DisplayName = "姓名")]
            [Display(Name = "Display姓名")]
            public string Name { get; set; }
            /// <summary>
            ///     年龄
            /// </summary>
            [ExporterHeader(DisplayName = "年龄")]
            public int Age { get; set; }
        }

PdfExporter 通过Name属性来定义文档标题
ExporterHeader DisplayName用来定义属性名称
Display同样定义属性名称，但是优先级小于ExporterHeader

通过修改上述代码执行结果如下所示：

3.导出PDF收据

创建导出模板

@using DocumentFormat.OpenXml.EMMA
<!DOCTYPE html>

<html lang="en" xmlns="http://www.w3.org/1999/xhtml">

<head>
    <meta charset="utf-8"/>
    <title></title>
    <style type="text/css">
        body { font-family: SimSun !important; }

        p { margin: 0px; }

        footer {
            color: #333;
            font-size: 1.2rem;
            margin-bottom: 1.5rem;
            margin-right: 5%;
            margin-top: 1.2rem;
            text-align: right;
        }

        table,
        td {
            border: 1px solid #444;
            border-collapse: collapse;
            /* text-align: center; */
            height: 2rem;
            padding: 5px;
        }
    </style>
</head>

<body>
<p style="color: #000; font-size: 1.8rem; height: 32px; text-align: center;">
    @Model.Title
</p>
<p style="color: #333; font-size: 1.2rem; margin-left: 5%; margin-top: 1%;">
    <text>NO：@Model.Data.Code</text>
    <text style="padding-left: 52%; text-align: right;">交易时间：@Model.Data.TradeTime.ToString("yyyy-MM-dd HH:mm:ss")</text>
</p>

<table width="90%" style="margin-left: 5%; margin-top: 1%;">
    <tr style="font-size: 1rem;">
        <td style="text-align: center; width: 11%;">交款姓名</td>
        <td colspan="2">@Model.Data.Name</td>
        <td style="text-align: center; width: 13%;">身份证号码</td>
        <td colspan="3">@Model.Data.IdNo</td>
    </tr>
    <tr style="font-size: 1rem;">
        <td style="text-align: center">交易金额</td>
        <td colspan="6">
            <span>￥：@Model.Data.Amount</span>
            <span style="padding: 0 2% 0 2%;">人民币(大写):</span>
            <span>@Model.Data.UppercaseAmount</span>
        </td>
    </tr>
    <tr style="font-size: 1rem;">
        <td style="text-align: center">收款方式</td>
        <td colspan="2">@Model.Data.PaymentMethod</td>
        <td style="text-align: center; width: 13%;">交易状态</td>
        <td colspan="3">@Model.Data.TradeStatus</td>
    </tr>

    <tr style="font-size: 1rem;">
        <td style="text-align: center">收款事由</td>
        <td style="width: 22.3%;">@Model.Data.Remark</td>
        <td style="text-align: center; width: 11%;">入学年级</td>
        <td style="width: 22.3%;" colspan="2">@Model.Data.Grade</td>
        <td style="text-align: center; width: 11%;">专业</td>
        <td style="width: 22.3%;">@Model.Data.Profession</td>
    </tr>


</table>
</body>
</html>

创建Dto类
   [Exporter(Name = "湖南心莱信息科技有限公司电子收款凭证")]
    public class ReceiptInfo
    {
        /// <summary>
        ///     交易时间
        /// </summary>
        public DateTime TradeTime { get; set; }
        /// <summary>
        ///     姓名
        /// </summary>
        public string Name { get; set; }
        /// <summary>
        ///     身份证
        /// </summary>
        public string IdNo { get; set; }
        /// <summary>
        ///     金额
        /// </summary>
        public decimal Amount { get; set; }
        /// <summary>
        ///     支付方式
        /// </summary>
        public string PaymentMethod { get; set; }
        /// <summary>
        ///     交易状态
        /// </summary>
        public string TradeStatus { get; set; }
        /// <summary>
        ///     备注
        /// </summary>
        public string Remark { get; set; }
        /// <summary>
        ///     年级
        /// </summary>
        public string Grade { get; set; }
        /// <summary>
        ///     专业
        /// </summary>
        public string Profession { get; set; }
        /// <summary>
        ///     收款人
        /// </summary>
        public string Payee { get; set; }
        /// <summary>
        ///     大写金额
        /// </summary>
        public string UppercaseAmount { get; set; }
        /// <summary>
        ///     编号
        /// </summary>
        public string Code { get; set; }
    }

如上代码片段通过Exporter 特性去指定模板中的Title，当然在我们实际开发中也可以不通过该属性去做指定，毕竟我们这一块也是完全自定义的

怎么使用？

  public async Task ExportReceipt()
        {
            var tplPath = Path.Combine(Directory.GetCurrentDirectory(), "TestFiles", "ExportTemplates",
                "receipt.cshtml");
            var tpl = File.ReadAllText(tplPath);
            var exporter = new PdfExporter();
            //此处使用默认模板导出
            var result = await exporter.ExportByTemplate("test.pdf",
                new ReceiptInfo
                {
                    Amount = 22939.43M,
                    Grade = "2019秋",
                    IdNo = "43062619890622xxxx",
                    Name = "张三",
                    Payee = "湖南心莱信息科技有限公司",
                    PaymentMethod = "微信支付",
                    Profession = "运动训练",
                    Remark = "学费",
                    TradeStatus = "已完成",
                    TradeTime = DateTime.Now,
                    UppercaseAmount = "贰万贰仟玖佰叁拾玖圆肆角叁分",
                    Code = "19071800001"
                }, tpl);
        }

通过上述代码我们需要进行指定传递我们模板路径及模板内容，最终导出效果如下：

4.批量导出PDF收据

创建模板

    ```html

<!DOCTYPE html>

<html lang="en" xmlns="http://www.w3.org/1999/xhtml">

<head>
<meta charset="utf-8"/>
<title></title>
<style type="text/css">

    p { margin: 0px; }
    footer {

        font-size: 1.2rem;
        margin-bottom: 1.5rem;
        margin-right: 5%;
        margin-top: 1.2rem;
        text-align: right;
    }
    table,
    td {
        border: 1px solid #444;
        border-collapse: collapse;
        height: 2rem;
        padding: 5px;
    }
    .evenNum {
        margin-bottom: 8%;
        padding-top: 10%;
    }

                <span>@Model.Data.ReceiptInfoInputs[i].UppercaseAmount</span>
            </td>
        </tr>
        <tr style="font-size: 1rem;">
            <td style="text-align: center">收款方式</td>
            <td colspan="2">@Model.Data.ReceiptInfoInputs[i].PaymentMethod</td>
            <td style="text-align: center; width: 13%;">交易状态</td>
            <td colspan="3">@Model.Data.ReceiptInfoInputs[i].TradeStatus</td>
        </tr>
        <tr style="font-size: 1rem;">
            <td style="text-align: center">收款事由</td>
            <td style="width: 22.3%;">@Model.Data.ReceiptInfoInputs[i].Remark</td>
            <td style="text-align: center; width: 11%;">入学年级</td>
            <td style="width: 22.3%;" colspan="2">@Model.Data.ReceiptInfoInputs[i].Grade</td>
            <td style="text-align: center; width: 11%;">专业</td>
            <td style="width: 22.3%;">@Model.Data.ReceiptInfoInputs[i].Profession</td>
        </tr>
      </table>
  </div>
}
</body>
</html>

- 创建Dto类
  ```csharp
