.NET Core 使用PDF打印
第一种方式 套打 （先做好PDF模版 在程序中只是填充数据）
1.先用word制作好模版 然后另存为pdf格式
2.下载adobe acrobat pro
3.选择工具 准备表单 会自动把没有内容的td单元格 还有___ 这种可以填的地方设置key值
4.需要导入iTextsharp这个包 如果没有就导入 iTextSharp.LGPLv2.Core
public FileResult DemoViewAsPdf() { //return null; //获取中文字体，第三个参数表示为是否潜入字体，但只要是编码字体就都会嵌入。 BaseFont baseFont = BaseFont.CreateFont(@"C:\Windows\Fonts\simsun.ttc,1", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED); //读取模板文件 PdfReader reader = new PdfReader(@"C:\Users\jiangchengbiao\Desktop\第一个打印文档.pdf"); //创建文件流用来保存填充模板后的文件 MemoryStream stream = new MemoryStream(); PdfStamper stamp = new PdfStamper(reader, stream); //设置表单字体，在高版本有用，高版本加入这句话就不会插入字体，低版本无用 //stamp.AcroFields.AddSubstitutionFont(baseFont); AcroFields form = stamp.AcroFields; //表单文本框是否锁定 stamp.FormFlattening = true; Dictionary<string, string> para = new Dictionary<string, string>(); para.Add("name", "蒋承标"); para.Add("age", "22"); para.Add("sex", "男"); para.Add("identity", "330328"); //填充表单,para为表单的一个（属性-值）字典 foreach (KeyValuePair<string, string> parameter in para) { //要输入中文就要设置域的字体; form.SetFieldProperty(parameter.Key, "textfont", baseFont, null); //为需要赋值的域设置值; form.SetField(parameter.Key, parameter.Value); } //按顺序关闭io流 stamp.Close(); reader.Close(); //生成文件 FileResult fileResult = new FileContentResult(stream.ToArray(), "application/pdf"); //设置了这个属性就是下载 //fileResult.FileDownloadName = "4.pdf"; return fileResult; }
这个action一定要是get请求的 这样才可以直接通过windows.open()请求
前端只需要 window.open("这个action的地址") 就可以直接显示或者下载这个pdf文档

在程序中生成PDF
添加iTextSharp.LGPLv2.Core包
string filePath = @"D:\pdf\"; //实例化在当前目录 创建 移动的实例方法 DirectoryInfo dirTime = new DirectoryInfo(filePath); //如果目录不存在 则创建 if (!dirTime.Exists) { dirTime.Create(); } //获取当前目录中文件的数量 string name = dirTime.GetFiles().Length + 1 + ".pdf"; filePath = filePath + name; //这个就是流对象 对于这种操作IO的 最后都需要清空流对象 var stream = new FileStream(filePath, FileMode.Create); Document document = new Document(PageSize.A4, 5f, 5f, 30f, 0f); PdfWriter writer = PdfWriter.GetInstance(document, stream);

***************用第二种方式在程序中动态生成PDF后 如果出现下面这种问题 IO流没有关闭 看看上面的stream流对象有没有调用Dispose()
具体案例可以在github上找
