C#之显示效果

窗体最大化（包含任务栏）：

 this.TopMost = true;
 this.Location = new Point(, );
 this.Size = Screen.PrimaryScreen.Bounds.Size;

窗体最大化（不包含任务栏）：

 this.Location = new Point(, );
 this.Size = Screen.PrimaryScreen.WorkingArea.Size;

textbox滚动到最下端：

 textBox.SelectionStart = textBox.TextLength - ;
 textBox.ScrollToCaret();

DatagridView滚动到最下：

 //计算dataGridView1可显示的最多行数
 int count = (dataGridView1.Height - dataGridView1.RowHeadersWidth) / dataGridView1.Rows[].Height;
 //设定最上端的显示行
 dataGridView1.FirstDisplayedScrollingRowIndex = num - count;

TabControl页面切换

    private void btnPage1_Click(object sender, EventArgs e)
    {
        tabPage1.Parent = this.tabControl1;
        tabPage2.Parent = null;
    }

    private void btnPage2_Click(object sender, EventArgs e)
    {
        tabPage1.Parent = null;
        tabPage2.Parent = this.tabControl1;
    }
