用户可以在打印设置里面的打印区域的自由选择或者点击打印控制的选择范围打印实现功能。

private void PrintRange()
{
    MxDrawUtility mxUtility = new MxDrawUtility();
    //点取第一点
    MxDrawPoint point = (MxDrawPoint)(mxUtility.GetPoint(null, "点取第一点..."));
    if (point == null)
        return;
    //点取第二点
    MxDrawPoint point1 = (MxDrawPoint)(mxUtility.GetPoint(null, "点取第二点..."));
    if (point1 == null)
        return;
    MxDrawPrint print = new MxDrawPrint();
    //开始打印  参数一为打印的范围左下角X1；参数二为打印的范围左下角Y1
    //参数三为打印的范围右上角X2 ；参数四为打印的范围右上角Y2
    if (print.Print(point.x, point.y, point1.x, point1.y))
    {
        MessageBox.Show("打印成功");
    }
    else
    {
        MessageBox.Show("打印失败");
    }
}

用户可以在CAD控件视区中选取所需打印内容进行打印，效果如下图所示：
