笔记 ,Winform 控件 enable false 不改颜色的实现

[System.Runtime.InteropServices.DllImport("user32.dll")]
public static extern int SetWindowLong(IntPtr hWnd, int nIndex, int wndproc);
[System.Runtime.InteropServices.DllImport("user32.dll")]
public static extern int GetWindowLong(IntPtr hWnd, int nIndex);

public const int GWL_STYLE = -16;
public const int WS_DISABLED = 0x8000000;

public static void SetControlEnabled(Control c, bool enabled)
{
if (enabled)
{ SetWindowLong(c.Handle, GWL_STYLE, (~WS_DISABLED) & GetWindowLong(c.Handle, GWL_STYLE)); }
else
{ SetWindowLong(c.Handle, GWL_STYLE, WS_DISABLED + GetWindowLong(c.Handle, GWL_STYLE)); }
}

 SetControlEnabled(this.label5, false);

可将对应控件 设置enable 不改颜色
