我正在做的是从数据库加载一些字符串，我做得很好。我读了它并将其转换为HTML ...有点..使用此代码：
private string StripHTML(string source)
{
try
{
string result;
// Remove HTML Development formatting
// Replace line breaks with space
// because browsers inserts space
result = source.Replace("\r", " ");
// Replace line breaks with space
// because browsers inserts space
result = result.Replace("\n", " ");
// Remove step-formatting
result = result.Replace("\t", string.Empty);
// Remove repeating spaces because browsers ignore them
result = System.Text.RegularExpressions.Regex.Replace(result,
@"( )+", " ");
// Remove the header (prepare first by clearing attributes)
result = System.Text.RegularExpressions.Regex.Replace(result,
@"<( )*head([^>])*>", "<head>",
System.Text.RegularExpressions.RegexOptions.IgnoreCase);
result = System.Text.RegularExpressions.Regex.Replace(result,
@"(<( )*(/)( )*head( )*>)", "</head>",
System.Text.RegularExpressions.RegexOptions.IgnoreCase);
result = System.Text.RegularExpressions.Regex.Replace(result,
"(<head>).*(</head>)", string.Empty,
System.Text.RegularExpressions.RegexOptions.IgnoreCase);
// remove all scripts (prepare first by clearing attributes)
result = System.Text.RegularExpressions.Regex.Replace(result,
@"<( )*script([^>])*>", "<script>",
System.Text.RegularExpressions.RegexOptions.IgnoreCase);
result = System.Text.RegularExpressions.Regex.Replace(result,

System.Text.RegularExpressions.RegexOptions.IgnoreCase);
//result = System.Text.RegularExpressions.Regex.Replace(result,
// @"(<script>)([^(<script>\.</script>)])*(</script>)",

result = System.Text.RegularExpressions.Regex.Replace(result,

问题是，有些字符串包含HTML颜色，例如：＆lt;＃D80000＆gt; StackOverFlow是个不错的论坛
我想要做的是将HTML颜色转换为颜色为HTML颜色之后的文本，意味着“StackOverFlow是一个不错的论坛变成红色或者颜色是什么（颜色总是X）
PS：这是一个工具提示......从数据库加载后我正在做什么：
string XZ = StripHTML(XZSecond);
Invoke(new MethodInvoker(delegate { tp.SetToolTip(OMG[i], Name + "\r" + XZ.Replace("Text", "").Replace("Text", "")); }));

据我所知，您只想将代码＃D80000转换为Color。在this link中获取答案可能会为您提供答案。
using System.Windows.Media;
Color color = (Color)ColorConverter.ConvertFromString("#FFDFD991");
作为Thorarin的回答
或
System.Drawing.Color col = System.Drawing.ColorTranslator.FromHtml("#FFCC66");
Color col = ColorConverter.ConvertFromString("#FFDFD991") as Color;
