this.textBox1.Copy();剪贴

这是控件自带的复制和剪贴

this.textBox1.Cut();复制

Clipboard类实现访问剪贴板

using System.ComponentModel;
using System.Windows.Forms;
using System.Data;

/**//**//**//**//**//**//**////<summary>

[STAThread]
staticvoid Main()
......{
Application.Run(new Form1());
}
privatevoid button1_Click(object sender, System.EventArgs e)
......{
if(textBox1.SelectedText !="")
Clipboard.SetDataObject(textBox1.SelectedText);
else
textBox2.Text ="No text selected in textBox1";
}
privatevoid button2_Click(object sender, System.EventArgs e)
......{
IDataObject iData = Clipboard.GetDataObject();
if(iData.GetDataPresent(DataFormats.Text))
......{
textBox2.Text = (String)iData.GetData(DataFormats.Text);
}
else
......{
textBox2.Text ="Could not retrieve data off the clipboard.";
}
}
}
}

还有直接的

//粘贴
private void tsbPaste_Click(object sender, EventArgs e)
{
    IDataObject iData = Clipboard.GetDataObject();
    if (iData.GetDataPresent(DataFormats.Text))
    {
        txtContent.Text = (String)iData.GetData(DataFormats.Text);
    }
 
}
 
//复制
private void tsbCopy_Click(object sender, EventArgs e)
{
    if (txtContent.Text != "")
    {
        Clipboard.SetDataObject(txtContent.Text);
        MessageBox.Show("已复制到剪贴板！");
    }
}
