如何触发打印预览对话框

本文关键字：对话框 打印 何触发 | 更新日期: 2023-09-27 17:55:43

using (PrintDialog printDialog1 = new PrintDialog())
{
   if (printDialog1.ShowDialog() == DialogResult.OK)
   {
       System.Diagnostics.ProcessStartInfo info = new System.Diagnostics.ProcessStartInfo(saveAs.ToString());
       info.Arguments = "'"" + printDialog1.PrinterSettings.PrinterName + "'"";
       info.CreateNoWindow = true;
       info.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
       info.UseShellExecute = true;
       info.Verb = "PrintTo";
       System.Diagnostics.Process.Start(info);
   }
}

上面的代码工作正常。我只是不知道如何更改代码以便我可以先预览Word文档。

如何触发打印预览对话框

好的，所以我昨晚回家后就做了这个，我相信我想通了。 它并不完美，但它确实让你朝着正确的方向前进。 顺便说一句，我为此创建了一个简单的WinForms应用程序，您需要编辑代码以满足您的需求。

代码：

namespace WindowsFormsApplication1
{
using System;
using System.Drawing;
using System.Windows.Forms;
using System.IO;
public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }
    private void button1_Click(object sender, EventArgs e)
    {
        System.Drawing.Printing.PrintDocument doc = new System.Drawing.Printing.PrintDocument();
        PrintPreviewDialog dlg = new PrintPreviewDialog();
        dlg.Document = doc;
        doc.PrintPage += new System.Drawing.Printing.PrintPageEventHandler(this.PrintPage);
        dlg.ShowDialog();
    }
    private void PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
    {
        try
        {
            string fileName = @"C:'Users'brmoore'Desktop'New Text Document.txt";
            StreamReader sr = new StreamReader(fileName);
            string thisIsATest = sr.ReadToEnd();
            sr.Close();
            System.Drawing.Font printFont = new System.Drawing.Font("Arial", 14);
            e.Graphics.DrawString(thisIsATest, printFont, Brushes.Black, 100, 100);
        }
        catch (Exception exc)
        {
            MessageBox.Show(exc.ToString());
        }
    }
}

}
