关于打印（Winform）?

[chinadragon5188]

C#，怎么实现呀，感觉特迷惑。

Windows 窗体 PrintDocument 组件用于设置一些属性，这些属性说明在基于 Windows 的应用程序中要打印什么内容以及打印文档的能力。可将它与 PrintDialog 组件一起使用来控制文档打印的各个方面。

使用 PrintDocument 组件
涉及 PrintDocument 组件的两种主要情况是：

简单的打印作业，如打印单个文本文件。在这种情况下，应将 PrintDocument 组件添加到 Windows 窗体，然后在 PrintPage 事件处理程序中添加打印文件的编程逻辑。该编程逻辑应以使用 Print 方法打印文档结束。此方法向打印机发送一个 Graphics 对象，该对象包含在 PrintPageEventArgs 类的 Graphics 属性中。

更为复杂的打印作业，如想要重新使用已编写的打印逻辑的情况。在这种情况下，应从 PrintDocument 组件派生一个新组件，并重写（参见 Visual Basic 的 重写 或 C# 的 重写）PrintPage 事件。

将 PrintDocument 组件添加到窗体后，它出现在 Windows 窗体设计器底部的栏中。

Visual Studio 中对此功能提供了广泛的支持。有关更多信息，请参见 PrintDocument 组件（Windows 窗体）。
public class PrintingExample : System.Windows.Forms.Form
{
private System.ComponentModel.Container components;
private System.Windows.Forms.Button printButton;
private Font printFont;
private StreamReader streamToPrint;

public PrintingExample() : base()
{
// The Windows Forms Designer requires the following call.
InitializeComponent();
}

// The Click event is raised when the user clicks the Print button.
private void printButton_Click(object sender, EventArgs e)
{
try
{
streamToPrint = new StreamReader
("C:\\My Documents\\MyFile.txt");
try
{
printFont = new Font("Arial", 10);
PrintDocument pd = new PrintDocument();
pd.PrintPage += new PrintPageEventHandler
(this.pd_PrintPage);
pd.Print();
}
finally
{
streamToPrint.Close();
}
}
catch(Exception ex)
{
MessageBox.Show(ex.Message);
}
}

// The PrintPage event is raised for each page to be printed.
private void pd_PrintPage(object sender, PrintPageEventArgs ev)
{
float linesPerPage = 0;

int count = 0;
float leftMargin = ev.MarginBounds.Left;
float topMargin = ev.MarginBounds.Top;
string line = null;

// Calculate the number of lines per page.
linesPerPage = ev.MarginBounds.Height /
printFont.GetHeight(ev.Graphics);

// Print each line of the file.
while(count < linesPerPage &&
((line=streamToPrint.ReadLine()) != null))
{
yPos = topMargin + (count *
printFont.GetHeight(ev.Graphics));
ev.Graphics.DrawString(line, printFont, Brushes.Black,
leftMargin, yPos, new StringFormat());
count++;
}

// If more lines exist, print another page.
if(line != null)
ev.HasMorePages = true;
else
ev.HasMorePages = false;
}


// The Windows Forms Designer requires the following procedure.
private void InitializeComponent()
{
this.components = new System.ComponentModel.Container();
this.printButton = new System.Windows.Forms.Button();

this.ClientSize = new System.Drawing.Size(504, 381);
this.Text = "Print Example";

printButton.ImageAlign =
System.Drawing.ContentAlignment.MiddleLeft;
printButton.Location = new System.Drawing.Point(32, 110);
printButton.FlatStyle = System.Windows.Forms.FlatStyle.Flat;
printButton.TabIndex = 0;
printButton.Text = "Print the file.";
printButton.Size = new System.Drawing.Size(136, 40);
printButton.Click += new System.EventHandler(printButton_Click);

this.Controls.Add(printButton);
}

// This is the main entry point for the application.
public static void Main(string[] args)
{
Application.Run(new PrintingExample());
}
}

水晶报表是否更好一些呢？

主要看你需要实现什么样的打印操作
