是否可以格式化WinForm标签中的某些文本而不是将文本分成多个标签?请忽略标签文本中的HTML标签;它只是用来说明我的观点。
例如:
Dim myLabel As New Label
myLabel.Text = "This is <b>bold</b> text. This is <i>italicized</i> text."
这会在标签中产生以下内容:
这是粗体文字。这是 斜体文字。

使用WinForms标签是不可能的。标签必须只有一种字体,只有一种尺寸和一种面。你有几个选择:
答案 1 :(得分:15)
不是真的,但你可以使用没有边框的只读RichTextBox伪造它。 RichTextBox支持RTF格式(rtf)。
答案 2 :(得分:11)
另一种解决方法,即晚会:如果您不想使用第三方控件,而您只是想提醒您注意标签中的某些文字,和你可以使用下划线,你可以使用LinkLabel。
请注意,许多人认为这是&#39; usability crime&#39;,但如果您没有为最终用户消费设计某些东西,那么它可能是您准备拥有的东西你的良心。
诀窍是添加禁用链接到文本中要加下划线的部分,然后全局设置链接颜色以匹配标签的其余部分。您可以在设计时设置除Links.Add()
之外的几乎所有必需属性,但这里它们在代码中:
linkLabel1.Text = "You are accessing a government system, and all activity " +
"will be logged. If you do not wish to continue, log out now.";
linkLabel1.AutoSize = false;
linkLabel1.Size = new Size(365, 50);
linkLabel1.TextAlign = ContentAlignment.MiddleCenter;
linkLabel1.Links.Clear();
linkLabel1.Links.Add(20, 17).Enabled = false; // "government system"
linkLabel1.Links.Add(105, 11).Enabled = false; // "log out now"
linkLabel1.LinkColor = linkLabel1.ForeColor;
linkLabel1.DisabledLinkColor = linkLabel1.ForeColor;
结果:

为我工作的解决方案 - 使用自定义RichEditBox。使用正确的属性,它将被视为具有大胆支持的简单标签。
1)首先,添加带有禁用插入符号的自定义RichTextLabel类:
public class RichTextLabel : RichTextBox
{
public RichTextLabel()
{
base.ReadOnly = true;
base.BorderStyle = BorderStyle.None;
base.TabStop = false;
base.SetStyle(ControlStyles.Selectable, false);
base.SetStyle(ControlStyles.UserMouse, true);
base.SetStyle(ControlStyles.SupportsTransparentBackColor, true);
base.MouseEnter += delegate(object sender, EventArgs e)
{
this.Cursor = Cursors.Default;
};
}
protected override void WndProc(ref Message m)
{
if (m.Msg == 0x204) return; // WM_RBUTTONDOWN
if (m.Msg == 0x205) return; // WM_RBUTTONUP
base.WndProc(ref m);
}
}
2)将句子拆分为带有IsSelected标志的单词,用于确定该单词是否应为粗体:
private void AutocompleteItemControl_Load(object sender, EventArgs e)
{
RichTextLabel rtl = new RichTextLabel();
rtl.Font = new Font("MS Reference Sans Serif", 15.57F);
StringBuilder sb = new StringBuilder();
sb.Append(@"{\rtf1\ansi ");
foreach (var wordPart in wordParts)
{
if (wordPart.IsSelected)
{
sb.Append(@"\b ");
}
sb.Append(ConvertString2RTF(wordPart.WordPart));
if (wordPart.IsSelected)
{
sb.Append(@"\b0 ");
}
}
sb.Append(@"}");
rtl.Rtf = sb.ToString();
rtl.Width = this.Width;
this.Controls.Add(rtl);
}
3)添加将文本转换为有效rtf的函数(支持unicode!):
private string ConvertString2RTF(string input)
{
//first take care of special RTF chars
StringBuilder backslashed = new StringBuilder(input);
backslashed.Replace(@"\", @"\\");
backslashed.Replace(@"{", @"\{");
backslashed.Replace(@"}", @"\}");
//then convert the string char by char
StringBuilder sb = new StringBuilder();
foreach (char character in backslashed.ToString())
{
if (character <= 0x7f)
sb.Append(character);
else
sb.Append("\\u" + Convert.ToUInt32(character) + "?");
}
return sb.ToString();
}

我通过构建包含{1}} UserControl
的{{1}}来解决此问题。 TransparentRichTextBox
是TransparentRichTextBox
,允许透明:
TransparentRichTextBox.cs:
RichTextBox
最终public class TransparentRichTextBox : RichTextBox
{
[DllImport("kernel32.dll", CharSet = CharSet.Auto)]
static extern IntPtr LoadLibrary(string lpFileName);
protected override CreateParams CreateParams
{
get
{
CreateParams prams = base.CreateParams;
if (TransparentRichTextBox.LoadLibrary("msftedit.dll") != IntPtr.Zero)
{
prams.ExStyle |= 0x020; // transparent
prams.ClassName = "RICHEDIT50W";
}
return prams;
}
}
}
充当UserControl
的包装。不幸的是,我必须以自己的方式将其限制为TransparentRichTextBox
,因为AutoSize
的{{1}}已被破坏。

}
使用颜色表替换颜色:
{\pard This is a paragraph!\par}
但请注意:始终将每个文本都包装在一个段落中。此外,可以堆叠不同的标签(即\b bold text\b0
\i italic text\i0
\ul underline text\ul0
),并忽略标签后面的空格字符。因此,如果您需要一个空格,请插入两个空格(即{\colortbl ;\red0\green77\blue187;}
{\pard The word \cf1 fish\cf0 is blue.\par
)。要转义\pard\b\i Bold and Italic\i0\b0\par
或\pard The word \bBOLD\0 is bold.\par
或\
,请使用前导{
。
有关更多信息,请full specification of the rich text format online。
使用这种非常简单的语法,您可以生成第一张图片中可以看到的内容。在第一张图片中附加到}
\
属性的富文本内容为:
RtfContent
如果要启用自动换行,请将最大宽度设置为所需的大小。但是,即使文本较短,这也会将宽度固定为最大宽度。
