C# .net windows 应用程序 - 打印文本框值

Question

我有两个文本框，当我在这些文本框中输入时，通过单击打印按钮，应该直接使用连接的打印机进行打印。谁能帮我我该怎么做？

Answer 1

下面的示例是使用/继承 PrintDocument 类的基本思想：

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
}

然后从表单的按钮事件中调用如下内容：

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

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

        printer.Print();    // very straightforward
}
