Answer 5

最简单的方法：
新建一个项目，在窗体Load事件中添加
private void Form1_Load(object sender, System.EventArgs e)
{
this.ControlBox = false;
this.Text = string.Empty;
}
就把以上的问题全解决了，就这么简单的两行代码
^_^

Answer 6

这一次是彻底的解决了
public const int WM_SYSCOMMAND=0x0112;
public const int SC_MOVE=0xF010;
public const int HTCAPTION=0x0002;
[System.Runtime.InteropServices.DllImport("user32.dll")]
public static extern bool ReleaseCapture();
public const int WM_SETTEXT = 0xC;
[System.Runtime.InteropServices.DllImport("user32.dll", EntryPoint="SendMessageA")]
public static extern int SendMessage (IntPtr hwnd, int wMsg, int wParam, string lParam);
private void Form1_Load(object sender, System.EventArgs e)
{
//使窗体不带标题栏，并且能够改变大小
this.ControlBox = false;
this.Text = string.Empty;
//设置任务栏标题
SendMessage( this.Handle , WM_SETTEXT , 0 , "^_^" );
}private void Form1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
{
//窗体移动
ReleaseCapture();
SendMessage(this.Handle,WM_SYSCOMMAND,SC_MOVE+HTCAPTION, null);
}

Answer 7

或者
设置任务栏标题
[System.Runtime.InteropServices.DllImport("user32.dll", EntryPoint="SetWindowText")]
public static extern int SetWindowText (
IntPtr hwnd,
string lpString
);
