C#中调用PDFCreator生成PDF文件
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
在C#中如何調用PDFCreator生成PDF文件呢？
第一步：安裝PDFCreator （這個好像是廢話）
第二步：創建C#項目，加入PDFCreator.exe COM引用
第三步：參見如下代碼：
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;
}
代碼很好懂，自己很懶，沒有把代碼重新寫成一個Project，直接把Project中的代碼貼上了，大家要用的話，還要稍微修改一下。要說的一點是PDFCreator不支持多線程，所以如果程序本身是多線程的話，需要在代碼中增加一個鎖機制，保證PDF生成的調用是單線程的。還有打印機的名字用的是默認值，沒有修改，不過這些問題是難不倒各位看官的。
