C#中如何复制一行文本

复制：

 private void button1_Click(object sender, System.EventArgs e) {

 　　// Takes the selected text from a text box and puts it on the clipboard.
　　if(textBox1.SelectedText != ”")
　　Clipboard.SetDataObject(textBox1.SelectedText);

 　　}

粘贴：

 private void button2_Click(object sender, System.EventArgs e) {

 　　// Declares an IDataObject to hold the data returned from the clipboard.

 　　// Retrieves the data from the clipboard.
　　IDataObject iData = Clipboard.GetDataObject();

 

 　　// Determines whether the data is in a format you can use.
　　if(iData.GetDataPresent(DataFormats.Text)) {

 　　// Yes it is, so display it in a text box.
　　textBox2.Text = (String)iData.GetData(DataFormats.Text);

 　　}

 }

 主要通过调用Clipborad的API完成。
