Question

A DirectoryNotFound exception keeps happening for no apparent reason. The exception is thrown in:

public static string[] getKeywords(string filename)  
{  
    string[] keywords = XElement.Load(filename).Elements("Keyword").Attributes("name").Select(n => n.Value).ToArray();  
    return keywords;  
}

BUT it is called in this method:

public static void SyntaxHighlight(SyntaxHighlighter.SyntaxRichTextBox textbox, Language language)  
{  
    switch (language)  
    {  
        case Language.Cmake:  
            textbox.Settings.Comment = "#";  
            string[] CmakeKeywords = getKeywords("APIs\\cmake.xml");  
            textbox.Settings.Keywords.AddRange(CmakeKeywords);  
            break;  
        case Language.CSharp:  
            textbox.Settings.Comment = "//";  
            string[] CSharpKeywords = getKeywords("APIs\\cs.xml");  
            textbox.Settings.Keywords.AddRange(CSharpKeywords);  
            break;  
        case Language.HTML:  
            textbox.Settings.Comment = "<!";  
            string[] HTMLKeywords = getKeywords("APIs\\html.xml");  
            textbox.Settings.Keywords.AddRange(HTMLKeywords);  
            break;  
        case Language.Python:  
            textbox.Settings.Comment = "#";  
            string[] PythonKeywords = getKeywords("APIs\\python.xml");  
            textbox.Settings.Keywords.AddRange(PythonKeywords);  
            break;  
    }  
}

UPDATE:
I have a folder in my project called APIs. I checked the file names several times. Here is the exception: Could not find a part of the path 'C:\Users\Mohit\Documents\Visual Studio 2010\Projects\Notepad\Notepad\bin\Debug\APIs\cs.xml'. Thats the EXACT path of the file!

Answer 1

There’s little hope of your program ever finding that folder. When you deploy your app, there is no project folder. The best way to organize it is to add the .xml files to your project with Project + Add Existing. Select them in Solution Explorer and in the Properties window set Build action = None and Copy to Output Directory = Copy if Newer. Build. That puts the files in the same directory as your .exe.

Find them back at runtime with System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetEntryAssembly().Location)
