在C#中如何调用PDFCreator生成PDF文件呢?
第一步:安装PDFCreator (这个好像是废话)
第二步:创建C#项目,加入PDFCreator.exe COM引用
第三步:参见如下代码:
public override void Process(ITask task, int index) { if (!File.Exists(Path.Combine(FromLocation, FromFilename))) { throw new FileNotFoundException("File: " + Path.Combine(FromLocation, FromFilename) + " does not exists"); } Monitor.Enter(lockObject); clsPDFCreator creator = null; try { creator = new clsPDFCreator(); creator.eError += new __clsPDFCreator_eErrorEventHandler(creator_eError); creator.eReady += new __clsPDFCreator_eReadyEventHandler(creator_eReady); String paramters = "/NoProcessingAtStartup"; if (!creator.cStart()) { throw new Exception("Cannot launch PDFCreator. Error: " + Error); } var opt = creator.cOptions; opt.UseAutosave = 1; opt.UseAutosaveDirectory = 1; opt.AutosaveDirectory = this.ToLocation; opt.AutosaveFormat = 0; opt.AutosaveFilename = this.ToFilename; creator.cOptions = opt; creator.cClearCache(); creator.cDefaultPrinter = "PDFCreator"; if (!creator.cIsPrintable(Path.Combine(FromLocation, FromFilename))) { throw new Exception("File: " + Path.Combine(FromLocation, FromFilename) + " is not printable."); } creator.cPrintFile(Path.Combine(FromLocation, FromFilename)); creator.cPrinterStop = false; Ready = false; var duration = new TimeSpan(0, 0, 0, TimeoutInSec); DateTime lastCheck = DateTime.Now; DateTime startTime = lastCheck; while (!Ready && ((lastCheck - startTime) < duration)) { System.Threading.Thread.Sleep(500); lastCheck = DateTime.Now; } creator.cPrinterStop = true; Thread.Sleep(1000); creator.cClose(); if (!Ready) { throw new Exception("PDF creation failed. This maybe due to timeout."); } } finally { Monitor.Exit(lockObject); } } void creator_eReady() { this.Ready = true; } void creator_eError() { Error = creator.cError.Description; }
代码很好懂,自己很懒,没有把代码重新写成一个Project,直接把Project中的代码贴上了,大家要用的话,还要稍微修改一下。要说的一点是PDFCreator不支持多线程,所以如果程序本身是多线程的话,需要在代码中增加一个锁机制,保证PDF生成的调用是单线程的。还有打印机的名字用的是默认值,没有修改,不过这些问题是难不倒各位看官的。
