我想获取当前存储在 Windows 剪贴板中的数据并将其保存在一个变量中,然后将数据放回剪贴板。
现在我正在使用这段代码:
object l_oClipBrdData = Clipboard.GetDataObject();
Clipboard.SetDataObject(l_oClipBrdData ,true);
但是在这样做之后剪贴板是空的。
我究竟做错了什么?
这是一个演示“剪贴板”对象的示例:
string text;
string[] a;
if (Clipboard.ContainsText())
{
text = Clipboard.GetText(TextDataFormat.Text);
// the following could have been done simpler with
// a Regex, but the regular expression would be not
// exactly simple
if (text.Length > 1)
{
// unify all line breaks to \r
text = text.Replace("\r\n", "\r").Replace("\n", "\r");
// create an array of lines
a = text.Split('\r');
// join all trimmed lines with a space as separator
text = "";
// can't use string.Join() with a Trim() of all fragments
foreach (string t in a)
{
if (text.Length > 0)
text += " ";
text += t.Trim();
}
Clipboard.SetDataObject(text, true);
}
}
Clipboard.GetDataObject()
will return the IDataObject
from the clipboard, if you want to get the actual data you can call GetData(typeof(dataType))
Example:
int mydata = 100;
Clipboard.SetDataObject(mydata, true);
var clipData = Clipboard.GetDataObject().GetData(typeof(int));
There are also a lot of predifined dataTypes you can use
Example:
if (Clipboard.ContainsData(DataFormats.Bitmap))
{
var clipData = Clipboard.GetData(DataFormats.Bitmap);
}
传递给 SetDataObject() 的对象应该支持序列化。如果这是您自己的类型,请使用 [Serializable] 属性对其进行标记。

Clipboard.Flush();
之后尝试调用SetDataObject()
。
