我正在开发一个Web-API项目，我对微软帮助页面自动生成的文档印象深刻。
我使用官方网站creating Help Pages
启用了自定义文档文档生成成功但是<See cref="">标记中的类的引用似乎都没有添加到描述中，HelpPages只是忽略它们（这是有原因的）。
我真的很想在我的项目中使用这个功能，我搜索了很多（有时候很近），但没有一个给出令人信服的答案。
这就是为什么我决定将我的解决方案发布到这个调整上，并希望让其他程序员受益，并为他们节省一些时间和精力。 （我的答案在下面的回复中）
答案 0 :(得分：2)
我的解决方案如下：
return node.Value.Trim();更改为return node.InnerXml; @using System.Web.Http; @using MyProject.Areas.HelpPage.Controllers; @using MyProject.Areas.HelpPage; @using MyProject.Areas.HelpPage.ModelDescriptions @using System.Text.RegularExpressions @model string
@{
int @index = 0;
string @xml = Model;
if (@xml == null)
@xml = "";
Regex @seeRegex = new Regex("<( *)see( +)cref=\"([^\"]):([^\"]+)\"( *)/>");//Regex("<see cref=\"T:([^\"]+)\" />");
Match @xmlSee = @seeRegex.Match(@xml);
string @typeAsText = "";
Type @tp;
ModelDescriptionGenerator modelDescriptionGenerator = (new HelpController()).Configuration.GetModelDescriptionGenerator();
}
@if (xml !="" && xmlSee != null && xmlSee.Length > 0)
{
while (xmlSee != null && xmlSee.Length > 0)
{
@MvcHtmlString.Create(@xml.Substring(@index, @xmlSee.Index - @index))
int startingIndex = xmlSee.Value.IndexOf(':')+1;
int endIndex = xmlSee.Value.IndexOf('"', startingIndex);
typeAsText = xmlSee.Value.Substring(startingIndex, endIndex - startingIndex); //.Replace("<see cref=\"T:", "").Replace("\" />", "");
System.Reflection.Assembly ThisAssembly = typeof(ThisProject.Controllers.HomeController).Assembly;
tp = ThisAssembly.GetType(@typeAsText);
if (tp == null)//try another referenced project
{
System.Reflection.Assembly externalAssembly = typeof(MyExternalReferncedProject.AnyClassInIt).Assembly;
tp = externalAssembly.GetType(@typeAsText);
}
if (tp == null)//also another referenced project- as needed
{
System.Reflection.Assembly anotherExtAssembly = typeof(MyExternalReferncedProject2.AnyClassInIt).Assembly;
tp = anotherExtAssembly .GetType(@typeAsText);
}
if(tp == null)//case of nested class
{
System.Reflection.Assembly thisAssembly = typeof(ThisProject.Controllers.HomeController).Assembly;
//the below code is done to support detecting nested classes.
var processedTypeString = typeAsText;
var lastIndexofPoint = typeAsText.LastIndexOf('.');
while (lastIndexofPoint > 0 && tp == null)
{
processedTypeString = processedTypeString.Insert(lastIndexofPoint, "+").Remove(lastIndexofPoint + 1, 1);
tp = SPLocatorBLLAssembly.GetType(processedTypeString);//nested class are recognized as: namespace.outerClass+nestedClass
lastIndexofPoint = processedTypeString.LastIndexOf('.');
}
}
if (@tp != null)
{
ModelDescription md = modelDescriptionGenerator.GetOrCreateModelDescription(tp);
@Html.DisplayFor(m => md.ModelType, "ModelDescriptionLink", new { modelDescription = md })
}
else
{
@MvcHtmlString.Create(@typeAsText)
}
index = xmlSee.Index + xmlSee.Length;
xmlSee = xmlSee.NextMatch();
}
@MvcHtmlString.Create(@xml.Substring(@index, @xml.Length - @index))
}
else
{
@MvcHtmlString.Create(@xml);
}
最后转到：ProjectName \ Areas \ HelpPage \ Views \ Help \ DisplayTemplates ** Parameters.cshtml **
在线＆＃39; 20＆＃39;我们有与文档中的描述相对应的代码
替换这个：
<td class="parameter-documentation">
<p>
@parameter.Documentation
</p>
</td>
有了这个：
<td class="parameter-documentation">
<p>
@Html.Partial("_XML_SeeTagsRenderer", (@parameter.Documentation == null? "" : @parameter.Documentation.ToString()))
</p>
</td>
＆安培;你现在必须让它工作 注意：
<see cref="MyClass">，我工作正常<see cref>中找到的任何未找到的类都会在说明中打印出它的全名（例如，如果您引用属性或命名空间，则代码不会将其标识为一个类型/类，但它将被打印）答案 1 :(得分：0)
我已经实现了处理xml文档块的类，并将文档标记更改为html标记。
/// <summary>

string result = helpBlock;
Match match = null;
while ((match = HelpBlockRenderer.regexSeeTag.Match(result)).Success)
{
var originalValues = match.Value;
var prefix = match.Groups["prefix"].Value;
var anchorText = string.Empty;
var link = string.Empty;
switch (prefix)
{
case "T":
{
// if See tag has reference to type, then get value from member regex group.
var modelType = match.Groups["member"].Value;
anchorText = modelType.Substring(modelType.LastIndexOf(".") + 1);
link = urlHelper.Action("ResourceModel", "Help",

break;
}
case "M":

if (apiDescriptor != null)

// So, in case if See tag contains link to model member, replace link with link to model class.
var modelType = match.Groups["member"].Value.Substring(0, match.Groups["member"].Value.LastIndexOf("."));
anchorText = modelType.Substring(modelType.LastIndexOf(".") + 1);

break;
}
}
// Build the anchor.
var anchor = string.Format("<a href=\"{0}\">{1}</a>", link, anchorText);
result = result.Replace(originalValues, anchor);

Regex endTagRegex = new Regex(string.Format("</{0}>", key), RegexOptions.IgnoreCase);

return descriptions.FirstOrDefault(x => x.ActionDescriptor.ActionName.Equals(action) &&
x.ActionDescriptor.ControllerDescriptor.ControllerName == controller);
}
return null;
}
}
要使用它，您需要更改XmlDocumentationProvider类：
private static string GetTagValue(XPathNavigator parentNode, string tagName)
{
if (parentNode != null)
{
XPathNavigator node = parentNode.SelectSingleNode(tagName);
if (node != null)
{
return node.InnerXml;
}
}
return null;
}
然后我编写了扩展类来直接从视图中使用这个类：
/// <summary>
/// Represents html help content extension class.
/// Contains methods to convert Xml help blocks to html string.
/// </summary>
public static class HtmlHelpContentExtensions
{
/// <summary>
/// Converts help block in xml format to html string with proper tags, links and etc.
/// </summary>
/// <param name="helpBlock">The help block content.</param>
/// <param name="urlHelper">The url helper for link building.</param>
/// <returns>The resulting html string.</returns>
public static HtmlString ToHelpContent(this string helpBlock, UrlHelper urlHelper)
{
// Initialize your rendrer here or take it from IoC
return renderer.RenderHelpBlock(helpBlock, urlHelper);
}
}
最后，例如在Parameters.cshtml中：
<td class="parameter-documentation">
<p>@parameter.Documentation.ToHelpContent(Url)</p>
@if(!string.IsNullOrEmpty(parameter.Remarks))
{
<p>@parameter.Remarks.ToHelpContent(Url)</p>
}
