String Manipulation with C#'s TrimStart() and TrimEnd()

The TrimStart() and TrimEnd() methods, which allow developers to easily trim leading and trailing characters from strings.TrimStart() and TrimEnd() are two string manipulation methods provided by C#. Both methods enable the removal of specified characters from the beginning (leading) or end (trailing) of a given string.

Overloads of TrimStart() and TrimEnd() Method with Examples

TrimStart()

The basic TrimStart() method removes all leading whitespace characters from the current string. This includes spaces, tabs, line breaks, and other similar characters. It is commonly used to clean user input or clean up strings before further processing.

string input = "   Hello, World!   ";
string trimmed = input.TrimStart();
Console.WriteLine(trimmed);

// Output: "Hello, World!   "

TrimEnd()

Likewise, the TrimEnd() method removes all trailing whitespace characters from the current string. It eliminates spaces, tabs, line breaks, and similar characters located at the end of the string.

string input = "   Hello, World!   ";
string trimmed = input.TrimEnd();
Console.WriteLine(trimmed);

// Output: "   Hello, World!"

TrimStart(Char)

The TrimStart(Char) overload removes all leading occurrences of a specified character from the current string. It allows you to target a specific character and remove it from the beginning of the string. This can be useful when you want to eliminate a specific prefix or formatting character.

string input = ">>>Hello, World!";
char prefix = '>';
string trimmed = input.TrimStart(prefix);
Console.WriteLine(trimmed);

// Output: "Hello, World!"

TrimEnd(Char)

Likewise, The TrimEnd(Char) overload removes all trailing occurrences of a specific character from the current string.

string input = "Hello, World!<<<";
char suffix = '<';
string trimmed = input.TrimEnd(suffix);
Console.WriteLine(trimmed);

// Output: "Hello, World!"

TrimStart(Char[])

The TrimStart(Char[]) overload extends the functionality further by allowing you to specify an array of characters to be removed from the beginning of the string. It removes any leading occurrences of the characters present in the array. This enables you to remove multiple specific characters at once.

string input = "xyzHello, World!";
char[] prefix = { 'x', 'y', 'z' };
string trimmed = input.TrimStart(prefix);
Console.WriteLine(trimmed);

// Output: "Hello, World!"

TrimEnd(Char[]):

The TrimEnd() method allows you to specify an array of characters. It removes any trailing occurrences of the characters present in the array, making it possible to eliminate multiple specific characters simultaneously.

string input = "Hello, World!xyz";
char[] suffix = { 'x', 'y', 'z' };
string trimmed = input.TrimEnd(suffix);
Console.WriteLine(trimmed);

// Output: "Hello, World!"

Combining Overloads

You can also combine these overloads to achieve more complex trimming operations. For example, you can remove leading whitespace characters followed by a specific character or set of characters using multiple TrimStart() calls.

string input = "  ---Hello, World!";
char[] whitespaceChars = { ' ', '-' };
string trimmed = input.TrimStart().TrimStart(whitespaceChars);
Console.WriteLine(trimmed);

// Output: "Hello, World!"

Similar to TrimStart(), you can combine the TrimEnd() overloads to perform more intricate trimming operations. This allows you to remove trailing whitespace characters followed by a specific character or set of characters.

string input = "Hello, World! ---";
char[] whitespaceChars = { ' ', '-' };
string trimmed = input.TrimEnd().TrimEnd(whitespaceChars);
Console.WriteLine(trimmed);

// Output: "Hello, World!"

The TrimStart() and TrimEnd() methods in C# provide developers with powerful tools for manipulating strings by removing leading and trailing characters, respectively. These methods offer flexibility and convenience, allowing for efficient string sanitization, formatting, and data manipulation.

This blog is going to illustrate how to implement Entity Framework (EF) Core with SQL Server LocalDB. The Entity Framework Core enables access to data from the database. This allows developers to avoid having to write most of the data access code. And the SQL Server LocalDB works similarly to the SQL SERVER with few features. You can get the LocalDB when you install visual studio or visual studio express. You can find the .mdf and _log.ldf files in the C:/Users/{user} directory. Let see how to create a SQL Server LocalDB and implement Entity Framework Core Step 1: The first step is to add a connection. In the menu -> click Tools and select Connect to Database It will display the Add Connection window. Enter (localdb)\mssqllocaldb in the server name textbox. Then in the Select or enter a database, select master and click ok Now in the server explorer, you can find the master DB containing Tables, Views, Stored

This blog is going to explain what is SignalR and how to implement it in ASP.NET Core. SignalR is a real time application framework for ASP.NET Core. Using SignalR you can provide updated information without refreshing the page, for example poll results, game score, chat etc. Let's see how to achieve it in ASP.NET Core MVC. Step 1: First step I added the SignalR client library. To add a SignalR client library, Right click on the project in Solution Explorer and Add -> Client-Side Library. Select the provider as unpkg as shown in the image below. Enter the latest version of SignalR into the library. And selected signalr.js and signalr.min.js files. Finally clicked the install button to install the client library. Step 2: At this step I have created a VoteHub.cs class inside the Hubs folder(create a new folder called Hubs). This class inherits from the Hub class which is a base class of SignalR hub. The SendMessage method will be called by the connected client.

Localization in ASP.NET Core MVC with Example

Using Query Strings for Request Culture and Simplifying Localization with IStringLocalizer Interface Let’s see how to implement Localization in ASP.NET Core MVC. In the first example, I am going to use the IStringLocalizer Interface in the controller to implement Localization. Additionally, when the user passes the desired language through the query string, it will display content in that language. First, let’s configure the settings in the program.cs file. builder.Services.AddLocalization(options => options.ResourcesPath = "Resources");  The AddLocalization method adds the localization service to the service container. I have added the supported cultures here. I have added two cultures: en for English and nl for Dutch. In the RequestCultureProviders , I have included QueryStringRequestCultureProvider() . This allows the system to determine the culture information from the query string. UseRequestLocalization initializes a RequestLocalizationOptions objec
