C＃.net windows應用程序 - 打印文本框值

Question

當我在這些文本框中輸入文本時，通過單擊打印按鈕，它應該直接使用連接的打印機打印。任何人都可以幫助我，我應該怎麼做？

Answer 1

下面的例子是使用/繼承PrintDocument類的基本思想：

using System.Drawing.Printing; 

public class PrintDoc : PrintDocument 
{ 
    // there are other properties you can enter here 
    // for instance, page orientation, size, font, etc. 

    private string textout; 

    public string PrintText 
    { 
     get { return textout; } 
     set { textout = value; } 
    } 

    // you will also need to add any appropriate class ctor 
    // experiment with the PrintDocument class to learn more 
} 

從窗體的按鈕事件

然後，調用是這樣的：

public void PrintDocument() 
{ 
     //instance PrintDocument class 
     PrintDoc printer = new PrintDoc(); 

     //set PrintText 
     printer.PrintText = myTextBox.Text; 

     printer.Print(); // very straightforward 
}
