C#中调用PDFCreator生成PDF文件

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：

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。
