When working with URLs in C#, encoding is essential to ensure that special characters (like spaces, ?, &, and =) don’t break the URL structure. The recommended way to encode a string for a URL is by using Uri.EscapeDataString(), which converts unsafe characters into their percent-encoded equivalents.
string rawText = "hello world!"; string encodedText = Uri.EscapeDataString(rawText); Console.WriteLine(encodedText); // Output: hello%20world%21
This method encodes spaces as %20, making it ideal for query parameters.
For ASP.NET applications, you can also use HttpUtility.UrlEncode() (from System.Web), which encodes spaces as +:
using System.Web; string encodedText = HttpUtility.UrlEncode("hello world!"); Console.WriteLine(encodedText); // Output: hello+world%21
For .NET Core and later, Uri.EscapeDataString() is the preferred choice.
In C#, you can format an integer with commas (thousands separator) using ToString with a format specifier.
int number = 1234567; string formattedNumber = number.ToString("N0"); // "1,234,567" Console.WriteLine(formattedNumber);
Explanation:
"N0": The "N" format specifier stands for Number, and "0" means no decimal places. The output depends on the culture settings, so in regions where , is the decimal separator, you might get 1.234.567.
Alternative:
You can also specify culture explicitly if you need a specific format:
using System.Globalization; int number = 1234567; string formattedNumber = number.ToString("N0", CultureInfo.InvariantCulture); Console.WriteLine(formattedNumber); // "1,234,567"
Enums are a great way to define a set of named constants in C#, but what if you need to iterate over all values dynamically? You can use** Enum.GetValues()** to loop through an enum without hardcoding values.
enum Days { Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday } foreach (Days day in Enum.GetValues(typeof(Days))) { Console.WriteLine(day); }
This would output the following:
Sunday Monday Tuesday Wednesday Thursday Friday Saturday
Alternative: Using Enum.GetNames() If you only need the string names, use Enum.GetNames() instead:
foreach (string name in Enum.GetNames(typeof(Days))) { Console.WriteLine(name); }
Slow initial load times can drive users away from your React application. One powerful technique to improve performance is lazy loading - loading components only when they're needed.
Let's explore how to implement this in React.
By default, React bundles all your components together, forcing users to download everything upfront. This makes navigation much quicker and more streamlined once this initial download is complete.
However, depending on the size of your application, it could also create a long initial load time.
import HeavyComponent from './HeavyComponent'; import AnotherHeavyComponent from './AnotherHeavyComponent'; function App() { return ( <div> {/* These components load even if user never sees them */} <HeavyComponent /> <AnotherHeavyComponent /> </div> ); }
React.lazy() lets you defer loading components until they're actually needed:
import React, { lazy, Suspense } from 'react'; // Components are now loaded only when rendered const HeavyComponent = lazy(() => import('./HeavyComponent')); const AnotherHeavyComponent = lazy(() => import('./AnotherHeavyComponent')); function App() { return ( <div> <Suspense fallback={<div>Loading...</div>}> <HeavyComponent /> <AnotherHeavyComponent /> </Suspense> </div> ); }
Combine with React Router for even better performance:
import React, { lazy, Suspense } from 'react'; import { BrowserRouter, Routes, Route } from 'react-router-dom'; const Home = lazy(() => import('./pages/Home')); const Dashboard = lazy(() => import('./pages/Dashboard')); const Settings = lazy(() => import('./pages/Settings')); function App() { return ( <BrowserRouter> <Suspense fallback={<div>Loading...</div>}> <Routes> <Route path="/" element={<Home />} /> <Route path="/dashboard" element={<Dashboard />} /> <Route path="/settings" element={<Settings />} /> </Routes> </Suspense> </BrowserRouter> ); }
Implement these techniques in your React application today and watch your load times improve dramatically!
