请问winform 下 datagrid 如何单击右键选择一行？（急）

[lorylovenn]

小弟是想实现在datagrid里单击右键选中一行，然后进行操作（弹出菜单）。
现在小弟就是不懂 如何右键单击哪行，就能选种哪行？
谢谢各位大哥了，小弟先想各位拜个早年，祝大家新年发大财~ ：）

if(e.Button == System.Windows.Forms.MouseButtons.Right||e.Button == System.Windows.Forms.MouseButtons.Left)
{
//只選中本行,不選中本單元格
int rowindex=this.gridIN.CurrentRowIndex;
if(rowindex>=0){this.gridIN.Select(rowindex);}
}

不好意思,剛才不完整
#region select datagrid row record no select cell [ Custom Order ][ Select DataGrid a Row ]

private void gridIN_CurrentCellChanged(object sender, System.EventArgs e)
{
int rowindex=this.gridIN.CurrentRowIndex;
if(rowindex>=0){this.gridIN.Select(rowindex);}
}

private void gridIN_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e)
{
if(e.Button == System.Windows.Forms.MouseButtons.Right||e.Button == System.Windows.Forms.MouseButtons.Left)
{
//只選中本行,不選中本單元格
int rowindex=this.gridIN.CurrentRowIndex;
if(rowindex>=0){this.gridIN.Select(rowindex);}
}
}

private void gridIN_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)

private void gridIN_MouseMove(object sender, System.Windows.Forms.MouseEventArgs e)

gridname.UnSelect(gridname.CurrentRowIndex);
gridname.CurrentRowIndex=info.Row;
