C# 打印 word pdf PrintOut方法中OutputFileName参数问题

一、
1）参数Append如果为 true，则会将文档追加到 OutputFileName 参数指定的文件；
2）参数Append如果为 false，则会改写 OutputFileName 的内容。
3）参数PrintToFile
如果为 true，则将打印机指令发送到文件。请确保使用 OutputFileName 指定一个文件名。

二、C#直接打印word文档
using usingMicrosoft.Office.Interop.Word;
（通过添加引用-com组件，找office的word组件
///<summary>
/// 打印word
/// </summary>
/// <paramname="filepath">word文件路径</param>
/// <paramname="printername">指定的打印机</param>
public void Printword(stringfilepath,string printername)
{
//filepath=@"d:\b.doc";
//printername = "Microsoft XPS Document Writer";
try
{
System.Diagnostics.Process p = new System.Diagnostics.Process();
//不现实调用程序窗口,但是对于某些应用无效
p.StartInfo.CreateNoWindow = true;
p.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
//采用操作系统自动识别的模式
p.StartInfo.UseShellExecute = true;
//要打印的文件路径
p.StartInfo.FileName = filepath;
Help help = new Help();
help.LogMessage(filepath + "---------" + printername);
//指定执行的动作，是打印，即print，打开是 open
p.StartInfo.Verb = "print";
//获取当前默认打印机
string defaultPrinter = GetDefaultPrinter();
//将指定的打印机设为默认打印机
SetDefaultPrinter(printername);
//开始打印
p.Start();
//等待十秒
p.WaitForExit(10000);
//将默认打印机还原
SetDefaultPrinter(defaultPrinter);
}

{

help.LogMessage(filepath + "----" + printername + "-------"+ ex.Message);
}
}

}追问

doc.PrintOut（）中，oOutputFileName为oMissing时，是可以打印的，但在打印过程中，会出现要求填写PDF文件名称的对话框，我想实现的效果是在打印过程中不需要填写该PDF文件名，直接打印成程序中设置为PDF文件。如果将oOutputFileName赋值，如d:\test.PDF，可以生成该test.PDF的文件，但该文件无法使用，打开时会出现上述问题附图中的提示。
