c# - Comparing namespaces to see if they match -


I'm trying to compare namespaces to see if only in my method only throws the right exception With the right exceptions I mean the following:

  1. Exception from the same namespace.
  2. Exception from high namespace.
  3. Exception from the equivalent (and higher) system-namespace. Example:

    1. The method is in the namespace MyNamespace.Collections.Generic , so it can throw exceptions from MyNamespace.Collections.Generic .
    2. The method is in the namespace MyNamespace.Collections.Generic , so it is MyNamespace.Collections and MyNamespace .
    3. The method is in the namespace MyNamespace.Collections.Generic , so it can throw exceptions from System.Collections.Generic and System.Collections and system .

    The first section is quite easy; One part of the same name space check number 3 works; Because system namespace is always correct

    For other parts I tried the following: 

      string [exceptNamespaceSegments = exceptionNamespaceSegments. Except (classNamespaceSegments) ToArray (); If (except for appointments of names, the threshold == 1 & amp; amp; amp; amp; amp; amp; amp; amp; leave; Namespace section.Other default () == "system") return;

    What determines that the name-space-section (archive, generic) is also used in class-namespace. If this is the case, then the right exception is thrown.

    But this will not work for the case where the exception is in the namespace System.Collections.Generic.Something , because is not something class-namespace

    Come to think about it, it does not take into consideration the sequence. Then System.Generic.Collections will also be correct;

    In any way, can I write agar-statements in comparison to Segment every person?

Unless I am misinterpreting this question: you can try to do something like this , Which can find all permitted namespaces according to the norms. 

  Private static IEnumerable & lt; String & gt; GetAllowedNamespaces (type type) {const string system = "system"; String thisNamespace = type.Namespace; HashSet & LT; String & gt; HashSet = New Hashet & lt; String & gt; (); Hashset.Add (thisNamespace); Hashset.Add (system); Var parts = this namespace. Lamp ('.'); If (parts.Length & gt; 1) {string previous = string.Empty; Forrest (part part) {var current = string.IsNullOrEmpty (last)? Part: string.Format ("{0}. {1}", Previous, Part); Previous = current; Hashset.Add (current); } Back = string Empty; Leading (new part [] {system} .concact (parts. Skip (1))) var current = string .isial olive (last)? Part: string.Format ("{0}. {1}", Previous, Part); Previous = current; Hashset.Add (current); }} Return hashet; }

Then you can easily check the namespace fallout of the exception in this list, if there is no problem :)

Duplicate code is block, For a method to re-drill the principle can follow.

sqlite3 - UPDATE a table from the SELECT of another one -

I have the first table article where some data is missing. In the table, articles_tmp I have a part of the missing data. So I want to update the articles. Where the path path is data in articles_tmp.path where the path is not zero . With SQLite , it does not work: update article SET path = (SELECT at.path FROM Articles_tmp as AS, WHERE at.article_id = a.id and a.asp, the text is in the form and not on. It has been transmitted) where the path is null MS Access Along with, it works fine: Update Articles Join the Inner Articles at articles_tmp articles.id = articles_tmp.id SETP articles.path = articles_tmp.path Can anyone help? Sin CE SQL Server Syntax, which I provided, was not working, here this solution With whom I have come. A little modification of your original query, but with my "correlation" suggestion added. There is a SQL Bella for this: Here is the code: update article SET path = (SELECT path from articles_tmp AS T WHERE t.id

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ

javascript - Render HTML after each iteration in loop -

I'm trying to gradually increase the font size of text on a web page. The code works in my place, although the new HTML / CSS does not render after every iteration of the loop and when all this is done, then display only the text of 100 px size. To see the text as if it is slowly zooming, I need to do this JavaScript is down because it is being used from a different file here is what I have ... < Pre> & lt; P class = "game-title" style = "font-size: 50px" & gt; Test & lt; / P & gt; Function sleep (milliseconds) {var start = new date (). GetTime (); For (var i = 0; i & lt; 1e7; i ++) {if ((new date). GetTime () - start) & gt; Milliseconds {break; CSS ('font-size', 'parseInt ($ (' game-title '). CSS (' font-size ')) + 1 + "pixels"); } While (parasont ($ ('# text'). Css ('font-size')) & lt; = 100) {sleep (1000); IncreaseSize (); Using CSS: Use of jQuery (sample):
