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：

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。
