c# - XML Comments for nullable 2D Array -

-

how correct specify xml comments 2d array of nullable doubles? following gives me syntax error.

/// <returns>the <see cref="double[,]"/>.</returns> public double?[,] get2darray() {     ... }

if 2d array of doubles i'd use:

/// <returns>the <see cref="double{t,t}]"/>.</returns> public double[,] get2darray() {     ... }

and if single value i'd use:

/// <returns>the <see cref="nullable{double}"/>.</returns> public static double? getnullabledouble() {

i can't seem combine these 2 concepts correct comments.

after reading here, perhaps want,

/// <summary> /// gets 2d array /// </summary> /// <returns>the <see cref="t:double?[,]"/>.</returns> public double?[,] get2darray() {     ... }

as commented, rather multi-dimensional array (double?[,]) should consider jagged, internal .net implementation superior. additionaly, if think of interfaces promises, should make smallest possible promise, easier keep.

perhaps,

/// <summary> /// gets 2d array /// </summary> /// <returns> /// <see cref="t:ienumerable{ienumerable{double?}}"/> data. /// </returns>     public ienumerable<ienumerable<double?>> getdata() {     ... }

would suffice.

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
