C# 實現簡單列印的執行個體代碼

主表單代碼如下:

複製代碼 代碼如下:public partial class PrintFileForm : Form
{
public PrintFileForm()
{
InitializeComponent();
PrintFile prinFile = new PrintFile();
prinFile.Print();
}
}

列印檔案類如下:

複製代碼 代碼如下:class PrintFile
{
StreamReader sr = null;
Font printFont = new Font("宋體", 12);
public void Print()
{
try
{
sr = new StreamReader(@"F:\Temp.txt");
try
{
PrintDocument printDoc = new PrintDocument();
printDoc.PrintPage += printDoc_PrintPage;
printDoc.Print();
}
finally
{
sr.Close();
}

}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}

}

void printDoc_PrintPage(object sender, PrintPageEventArgs e)
{
string line = null;
//設定一頁的行數=列印範圍的高度除以字型高度.
float pageLine = e.MarginBounds.Height / printFont.GetHeight(e.Graphics);
//迴圈列印每一行
for (int count = 0; count < pageLine && ((line=sr.ReadLine())!=null); count++)
{
float singleLine=e.MarginBounds.Top+(count*printFont.GetHeight(e.Graphics));
e.Graphics.DrawString(line, printFont, Brushes.Black, e.MarginBounds.Left, singleLine);
}
//判斷是否繼續列印
if (line != null)
e.HasMorePages = true;
else
e.HasMorePages = false;

}
}
