I have added this xml doc to my method:
/// <summary>
/// Create an <see cref="ArgumentOutOfRangeException" /> with the message<br />
/// "The value '<paramref name="i_value" />' is out of the range of '<paramref name="i_range" />.<see cref="IRange{T}.LowerValue"/>' to '<paramref name="i_range" />.<see cref="IRange{T}.UpperValue"/>'."
/// </summary>
public static Exception Create_ArgumentOutOfRange<T> (string? i_prefix,
object i_value,
IRange<T> i_range,
string? i_suffix = null,
Exception? i_innerException = null)
and the xml doc is shown as
which is quite ugly and difficult to read.
Is there a way of leaving out "IRange<out T>" of the message, but still referring to the code element?
If I used the property on the argument directly:
/// "The value '<paramref name="i_value" />' is out of the range of '<paramref name="i_range.LowerValue" />' to '<paramref name="i_range.UpperValue" />'."
then I get
which is not that ugly, but the property name is written twice, and thus wrong and misleading.
I want to create a new lightweight tag in my local repo using LibGit2Sharp. I have no intent to push it to the remote (I'm using tags as short-term bookmarks); knowing how to also push to the remote would be handy, but I am most interested in just creating a tag in a local repo without pushing to the remote.
As follows:
using LibGit2Sharp;
/// <summary>
/// Create a lightweight tag in the specified local repo:
/// </summary>
/// <param name="tagName">Name to be given to the tag</param>
/// <param name="repoFolder">Repo folder location (path)</param>
/// <param name="commitSha">Hash identifying the commit to receive the tag</param>
public static void CreateTag(string tagName, string repoFolder, string commitSha)
{
using (var repo = new Repository(repoFolder))
{
var commit = repo.Lookup<Commit>(commitSha);
if (commit != null)
{
repo.ApplyTag(tagName, commitSha);
}
}
}
I wish to replace a TextBox, with a webbrowser to display messages in chat app
So I can add hyperlinks to videos, sites and pics, emoticons ...
But When I run the app, it cannot find the myfile.html which is in Debug folder ...
It does exists and loadable in firefox
List<string> lines = new List<string>();
lines.Add("<html>");
lines.Add("<body><table width=100%><br><br>Chat:");
lines.Add("<tr><font size=6><a href=music\\" + artist + ">
<img src=music\\" + artist + "\\info\\default.jpg alt=" + art + " height=200 width=200 />
</a>"+" " + path2 +"</font><br><br></tr>");
lines.Add("</table></body>");
lines.Add("</html>");
File.WriteAllLines("myfile.html", lines);
wb_Messages.Navigate("myfile.html");
I have tried
wb_Messages.Navigate("file:///myfile.html");
wb_Messages.Navigate(Application.StartupPath + #"myfile.html");
No Joy ...
Any Help Thanks ...
i can't use comments for this but could you try to use the following helpers i dug up from my project(s):
/// <summary>
/// Helpers for working with <see cref="System.IO.Path"/> or working with paths in general.
/// </summary>
public static class PathHelpers
{
/// <summary>
/// The default output directory, based on the on the currently executing <see cref="System.Reflection.Assembly"/>
/// </summary>
public static string CurrentOutPutDirectory => Path.GetDirectoryName(AssemblyHelper.ExecutableAssembly.GetName().CodeBase)?.Substring(6);
public static string CurrentOutPutDirectoryRoot => Path.GetPathRoot(CurrentOutPutDirectory);
/// <summary>
/// Checks if a string could be used in a path
/// <see href="https://stackoverflow.com/questions/2435894/net-how-do-i-check-for-illegal-characters-in-a-path#comment30899588_2435894"/>
/// </summary>
/// <param name="path">Path to check</param>
/// <returns></returns>
public static bool FilePathHasInvalidChars(string path)
{
return (!string.IsNullOrEmpty(path) && path.IndexOfAny(System.IO.Path.GetInvalidPathChars()) >= 0 && path.IndexOfAny(System.IO.Path.GetInvalidFileNameChars()) > 0);
}
}
/// <summary>
/// Helpers for dealing with <see cref="System.Reflection.Assembly"/>
/// </summary>
public static class AssemblyHelper
{
/// <summary>
/// The assembly that holds the executable. For this, <see cref="Assembly.GetEntryAssembly()"/> is used.
/// This looks at the current <see cref="AppDomain"/>.
/// <warn>A fallback value is used to get the executing assembly!</warn>
/// </summary>
public static Assembly ExecutableAssembly => Assembly.GetEntryAssembly() ?? Assembly.GetExecutingAssembly();
}
Then use var alltext = File.ReadAllText(Path.Combine(PathHelpers.CurrentOutPutDirectory, "YourFileIntheDebugFolder.txt)) (pseudo code) to check if it works and loads the html directly.
EDIT to display a html file in the webbrowser, use this top answer, and pass the alltext string.

I think it's because you use only file name instead of full path.
File.WriteAllLines("myfile.html", lines);
In this method you didn't specify full path, so it will try to save file in some default location. What location? No need to think about it now.
wb_Messages.Navigate("myfile.html");
This method tries to read data from file, but only file name is specified. It doesn't know where to find this file, so it will look in some default location also.
But default locations for both methods can be different. I don't know how it works internally, but maybe you will get some info in Microsoft documentation.
Simple solution:
// now filePath becomes "C:\something...\myfile.html"
string filePath = Path.GetFullPath("myfile.html");
// save data using full path
File.WriteAllLines(filePath, lines);
// navigate to file using full path
wb_Messages.Navigate(filePath);
I'm looking for a way to programmatically get the summary portion of Xml-comments of a method in ASP.net.
I have looked at the previous related posts and they do not supply a way of doing so in a web environment.
I can not use any 3rd party apps and due to a web environment, Visual studio plugin's aren't much use either.
The closest thing I have found to a working solution was the JimBlackler project, but it only works on DLL's.
Naturally, something like 'supply .CS file, get XML documentation' would be optimal.
Current situation
I have a web-service and trying to dynamically generate documentation for it.
Reading the Methods, and properties is easy, but getting the Summary for each method is throwing me off a bit.
/// <summary>
/// This Is what I'm trying to read
/// </summary>
public class SomeClass()
{
/// <summary>
/// This Is what I'm trying to read
/// </summary>
public void SomeMethod()
{
}
}
A Workaround - Using reflection on Program.DLL/EXE together with Program.XML file
If you take a look at the sibling .XML file generated by Visual Studio you will see that there is a fairly flat hierarchy of /members/member.
All you have to do is get hold on each method from your DLL via MethodInfo object. Once you have this object you turn to the XML and use XPATH to get the member containing the XML documentation for this method.
Members are preceded by a letter. XML doc for methods are preceded by "M:" for class by "T:" etc.
Load your sibling XML
string docuPath = dllPath.Substring(0, dllPath.LastIndexOf(".")) + ".XML";
if (File.Exists(docuPath))
{
_docuDoc = new XmlDocument();
_docuDoc.Load(docuPath);
}
Use this xpath to get the member representing the method XML docu
string path = "M:" + mi.DeclaringType.FullName + "." + mi.Name;
XmlNode xmlDocuOfMethod = _docuDoc.SelectSingleNode(
"//member[starts-with(#name, '" + path + "')]");
Now scan childnodes for all the rows of "///"
Sometimes the /// Summary contains extra blanks, if this bothers use this to remove
var cleanStr = Regex.Replace(row.InnerXml, #"\s+", " ");
The XML summary isn't stored in the .NET assembly - it's optionally written out to an XML file as part of your build (assuming you're using Visual Studio).
Consequently there is no way to "pull out" the XML summaries of each method via reflection on a compiled .NET assembly (either .EXE or .DLL) - because the data simply isn't there for you to pull out. If you want the data, you'll have to instruct your build environment to output the XML files as part of your build process and parse those XML files at runtime to get at the summary information.
You could 'document' your method using the System.ComponentModel.DataAnnotations.DisplayAttribute attribute, e.g.
[Display(Name = "Foo", Description = "Blah")]
void Foo()
{
}
then use reflection to pull the description at runtime.
A deleted post, made by #OleksandrIeremenko, on this thread links to this article https://jimblackler.net/blog/?p=49 which was the basis for my solution.
Below is a modification of Jim Blackler's code making extension methods off the MemberInfo and Type objects and adding code that returns the summary text or an empty string if not available.
Usage
var typeSummary = typeof([Type Name]).GetSummary();
var methodSummary = typeof([Type Name]).GetMethod("[Method Name]").GetSummary();

{
// Calculate the parameter string as this is in the member name in the XML
var parametersString = "";
foreach (var parameterInfo in methodInfo.GetParameters())
{
if (parametersString.Length > 0)
{
parametersString += ",";
}
parametersString += parameterInfo.ParameterType.FullName;
}
//AL: 15.04.2008 ==> BUG-FIX remove “()” if parametersString is empty
if (parametersString.Length > 0)
return XmlFromName(methodInfo.DeclaringType, 'M', methodInfo.Name + "(" + parametersString + ")");
else
return XmlFromName(methodInfo.DeclaringType, 'M', methodInfo.Name);

You can use Namotion.Reflection NuGet package to get these information:
string summary = typeof(Foo).GetXmlDocsSummary();
You can look at https://github.com/NSwag/NSwag - source for nuget NSwag.CodeGeneration - it gets summary as well, usage
var generator = new WebApiAssemblyToSwaggerGenerator(settings);<br/>
var swaggerService = generator.GenerateForController("namespace.someController");<br/>
// string with comments <br/>
var swaggerJson = swaggerService.ToJson();
(try ILSPY decompiler against your dll, you check code and comments)
If you have access to the source code you're trying to get comments for, then you can use Roslyn compiler platform to do that. It basically gives you access to all the intermediary compiler metadata and you can do anything you want with it.
It's a bit more complicated than what other people are suggesting, but depending on what your needs are, might be an option.
It looks like this post has a code sample for something similar.
For example Service Stack does this to with the Northwind database:
http://www.servicestack.net/ServiceStack.Northwind/customers/ALFKI?format=html
Is there anything that reads the database structure and relationships and output a report based on a primary id?
Obviously, I am looking into alternatives to servicestack.
I use LINQPad's .Dump() object visualizer for that. Download LINQPad from http://www.linqpad.net and reference the .exe in your project.
You will then have access to LINQPads .CreateXhtmlWriter() that can output a beautiful object graph visualization:
just by going:
var listOfItems = DataContext.Items.ToList();
listOfItems.Dump();
The following is not my code, but I cannot find the origin, so bear with me.
Use extension method to create the Xhtml dump and show it a browser:
public static class LinqPadExtensions
{
/// <summary>
/// Writes object properties to HTML
/// and displays them in default browser.
/// </summary>
/// <typeparam name="T"></typeparam>
/// <param name="o"></param>
/// <param name="heading"></param>
public static void Dump<T>(
this T o,
string heading = null
)
{
string localUrl =
Path.GetTempFileName() + ".html";
using (
var writer =
LINQPad.Util.CreateXhtmlWriter(true)
)
{
if (!String.IsNullOrWhiteSpace(heading))
writer.Write(heading);
writer.Write(o);
File.WriteAllText(localUrl, writer.ToString());
}
Process.Start(localUrl);
}
}
