我正在使用 Office 2007 中的 COM 对象来处理和打印 ms-office 文件。我对 word 和 excel 文档没有任何问题，但我就是无法打印 Power Point 文档。
下面的代码只是打开文件向打印机发送作业，但没有打印任何内容
我究竟做错了什么？=(
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace Main
{
class PrintPPoint
{
public static void PrintPPointDocument(string filename, int copies, string range)
{
Microsoft.Office.Interop.PowerPoint.Presentation work = null;
Microsoft.Office.Interop.PowerPoint.Application app = new Microsoft.Office.Interop.PowerPoint.ApplicationClass();
Microsoft.Office.Interop.PowerPoint.Presentations presprint = app.Presentations;
//app.Visible = Microsoft.Office.Core.MsoTriState.msoTrue;
work = presprint.Open(filename, Microsoft.Office.Core.MsoTriState.msoCTrue, Microsoft.Office.Core.MsoTriState.msoCTrue, Microsoft.Office.Core.MsoTriState.msoFalse);
work.PrintOptions.PrintInBackground = 0;
work.PrintOptions.ActivePrinter = app.ActivePrinter;
if (range.Equals("0"))
{
work.PrintOut(0, 1, app.ActivePrinter, copies, Microsoft.Office.Core.MsoTriState.msoFalse);
}
else
{
string[] toprintsheet = range.Split(new char[] { ',' });
foreach (string aux in toprintsheet)
{
work.PrintOptions.PrintInBackground = 0;
work.PrintOptions.ActivePrinter = app.ActivePrinter;
if (aux.Contains("-"))
{
int from = 0, to = 0;
string[] SplitRange = aux.Split(new char[] { '-' });
from = Convert.ToInt16(SplitRange[0]);
to = Convert.ToInt16(SplitRange[1]);
work.PrintOut(from, to, app.ActivePrinter, 1, Microsoft.Office.Core.MsoTriState.msoFalse);
}
else
{
work.PrintOut(Convert.ToInt16(aux), Convert.ToInt16(aux), app.ActivePrinter, copies, Microsoft.Office.Core.MsoTriState.msoFalse);
}
}
}
work.Close();
app.Quit();
}
}
}
