利用Lable控件输出九九乘法表,具体内容如下
首先建立一个空网站,之后选择添加新项,添加一个Web窗体。
进入.aspx文件之后,在设计界面中添加9个Lable控件。Lable控件在标准组中。得到的源代码是这样的。

接着,要实现九九乘法表的创建,还需要在.aspx.cs文件添加代码。

if (c <= r)
table.Rows[r].Cells[c].Text = ((r + 1)).ToString() + '×' + ((c + 1)).ToString() + '=' + (((r + 1) * (c + 1))).ToString();
}
}
form1.Controls.Add(table);
}
}
}

运行程序,得到的效果图如下:
这样,一个九九乘法表就输出来啦!
