这篇文章主要介绍了C#编程实现查看剪切板内容的方法,涉及C#针对剪切板操作的相关技巧,具有一定参考借鉴价值,需要的朋友可以参考下

本文实例讲述了c#编程实现查看剪切板内容的方法。分享给大家供大家参考，具体如下：

?
using system;
using system.collections.generic;
using system.componentmodel;
using system.data;
using system.drawing;
using system.linq;
using system.text;
using system.windows.forms;
namespace windowsformsapplication49
{
  public partial class form1 : form
  {
    public form1()
    {
      initializecomponent();
    }
    private void form1_load(object sender, eventargs e)
    {
      radiobutton1.checked = true;
      picturebox1.visible = false;
      textbox1.visible = true;
    }
    //“查看”按钮
    private void button1_click(object sender, eventargs e)
    {
      idataobject data;//为传送数据提供与格式无关的接口
      string format = formatstring();
      if (format == "bitmap")
      {
        textbox1.visible = false;
        picturebox1.visible = true;
        data = clipboard.getdataobject();//检索位于当前系统剪切板的数据
        if (data.getdatapresent(format))//确定此实例中存储的数据是否与指定的格式关联，返回布尔
        {
          picturebox1.image = (bitmap)data.getdata(format);//检索与指定的格式关联的数据
          picturebox1.sizemode = pictureboxsizemode.stretchimage;
        }
        else
        {
          messagebox.show("格式不正确", "提示");
        }
      }
      else
      {
        textbox1.visible = true;
        picturebox1.visible = false;
        data = clipboard.getdataobject();
        if (data.getdatapresent(format))
        {
          textbox1.text = (string)data.getdata(format);
        }
        else
        {
          messagebox.show("格式不正确", "提示");
        }
      }
    }
    private string formatstring()
    {
      string format = "";
      if (radiobutton1.checked) format = dataformats.text;//得到idataobject里面数据的格式
      if (radiobutton2.checked) format = dataformats.rtf;
      if (radiobutton3.checked) format = dataformats.bitmap;
      if (radiobutton4.checked) format = dataformats.html;
      return format;
    }
  }
}
