Gam*_*ega 5 c# forms size titlebar caption
有没有办法使表单的大小适应其标题/标题文本的大小?
例如,官方C#消息框表单将调整其标题文本的大小(注意lorem ipsum):

其他表单不会将其大小调整为标题文本的大小:

相反,在末尾添加省略号以适合设计器的"大小"属性中提到的大小.
有没有办法让表单调整到标题的大小而不是我们提到的大小?如果没有,有没有办法获得文本的全长,以便我们可以将其分配给表单?
我尝试使用设置表单的宽度
int topTextWidth = TextRenderer.MeasureText(this.Text, this.Font).Width;
this.Width = topTextWidth;

但this.Font显然是指另一种字体大小.
对于那些想要完整答案的人来说,就是这样.
根据标题文本调整表单大小的实际行如下:
this.Width = TextRenderer.MeasureText(this.Text, SystemFonts.CaptionFont).Width + AllButtonsAndPadding;

AllButtonsAndPadding包含所有按钮的宽度(最小化,最大化和关闭),窗口边框和图标.获取这些信息需要一些编码.这是一个完整自我调整大小的表单示例,无论您放置什么按钮或图标.
