WinForm 界面美化

大家好，又见面了，我是你们的朋友全栈君。

主界面的扁平化

更改winform自带的MainForm窗体属性
将主窗体FormBorderStyle更改为None，这样就得到了一个无边框的窗体

调节背景色，找到自己喜欢的颜色，输入到BackColor属性中

在主窗体的Mouse_Down中添加如下事件，实现窗体随意拖动：

[DllImport("user32.dll")]
public static extern bool ReleaseCapture();
[DllImport("user32.dll")]

public static extern bool SendMessage(IntPtr hwnd, int wMsg, int wParam, int lParam);
public const int WM_SYSCOMMAND = 0x0112;
public const int SC_MOVE = 0xF010;
public const int HTCAPTION = 0x0002;

private void Form6_MouseDown(object sender, MouseEventArgs e)
{ 
   
    ReleaseCapture();
    SendMessage(this.Handle, WM_SYSCOMMAND, SC_MOVE + HTCAPTION, 0);       
}

添加最小化、退出事件的按钮，背景色BackColor和字体色Forecolor设置为与界面颜色较为搭配的，将按钮的FlatStyle设置为Popup，它会自己随着界面风格调整

最小化和退出的代码如下：

private void min_Click(object sender, EventArgs e)
{ 
   
    this.WindowState = FormWindowState.Minimized;
}

private void exit_Click(object sender, EventArgs e)
{ 
   

    this.Close();
}

基本控件实现美化

tabcontrol美化
通过tabcontrol的drawitem事件，来达到改变tabpage字体、字体颜色以及背景色的目的

private void tabControl1_DrawItem(object sender, DrawItemEventArgs e)
{ 
   
	   SolidBrush back = new SolidBrush(Color.FromArgb(45, 45, 48));
	   SolidBrush white = new SolidBrush(Color.FromArgb(122, 193, 255));
	   Rectangle rec = tabControl1.GetTabRect(0);
	   e.Graphics.FillRectangle(back, rec);
	   Rectangle rec1 = tabControl1.GetTabRect(1);
	   e.Graphics.FillRectangle(back, rec1);
	   StringFormat sf = new StringFormat();
	   sf.Alignment = StringAlignment.Center;
	   for (int i = 0; i < tabControl1.TabPages.Count; i++)
	   { 
   
	       Rectangle rec2 = tabControl1.GetTabRect(i);
	       e.Graphics.DrawString(tabControl1.TabPages[i].Text, new Font("微软雅黑", 9), white, rec2, sf);
	   }
}
