c# - How to convert a StringBuilder to a string array

c# example - convert stringbuilder to string array
The following asp.net c# example code demonstrate us how can we convert a StringBuilder objectto a String Array programmatically at run time in an asp.net application. .Net framework's StringBuilder Classrepresent a mutable string of characters.

StringBuilder class has no built in method or property to convert a StringBuilder object to a String Array object.We also cannot directly convert a StringBuilder object to a String Array object.

To convert a StringBuilder object to a String Array, at first we need to convert the StringBuilder object to a String object.StringBuilder.ToString() method allow us to convert the value of a StringBuilder object to a string which data type isSystem.String.

String Class String.Split(Char[]) overloaded method return a String Array that contains the substrings in this instancethat are delimited by elements of a specified Unicode character array. String.Split(Char[]) method require to pass aparameter named 'separator' which value type is System.Char[].

The parameter represent an array of Unicode charactersthat delimit the substrings in this instance, an empty array that contains no delimiters or null.String.Split() method return an array object as System.String[].

In this example code, we uses an empty space (white space/blank space) as delimiter of StringBuilder object.The Split() method return an array object with elements those are generated from StringBuilder characters splitby white space delimiter. Finally, we convert a StringBuilder object to a String Array with elements splitby specified delimiter.

Restricting Jetpack Compose TextField to Numeric Input Only

Jetpack Compose has revolutionized Android development with its declarative approach, enabling developers to build modern, responsive UIs more efficiently. Among the many components provided by Compose, TextField is a critical building block for user input. However, ensuring that a TextField accepts only numeric input can pose challenges, especially when considering edge cases like empty fields, invalid characters, or localization nuances. In this blog post, we'll explore how to restrict a Jetpack Compose TextField to numeric input only, discussing both basic and advanced implementations. Why Restricting Input Matters Restricting user input to numeric values is a common requirement in apps dealing with forms, payment entries, age verifications, or any data where only numbers are valid. Properly validating input at the UI level enhances user experience, reduces backend validation overhead, and minimizes errors during data processing. Compose provides the flexibility to implement ...

jetpack compose - TextField remove underline

Compose TextField Remove Underline The TextField is the text input widget of android jetpack compose library. TextField is an equivalent widget of the android view system’s EditText widget. TextField is used to enter and modify text. The following jetpack compose tutorial will demonstrate to us how we can remove (actually hide) the underline from a TextField widget in an android application. We have to apply a simple trick to remove (hide) the underline from the TextField. The TextField constructor’s ‘colors’ argument allows us to set or change colors for TextField’s various components such as text color, cursor color, label color, error color, background color, focused and unfocused indicator color, etc. Jetpack developers can pass a TextFieldDefaults.textFieldColors() function with arguments value for the TextField ‘colors’ argument. There are many arguments for this ‘TextFieldDefaults.textFieldColors()’function such as textColor, disabledTextColor, backgroundColor, cursorC...

jetpack compose - Image clickable

Compose Image Clickable The Image widget allows android developers to display an image object to the app user interface using the jetpack compose library. Android app developers can show image objects to the Image widget from various sources such as painter resources, vector resources, bitmap, etc. Image is a very essential component of the jetpack compose library. Android app developers can change many properties of an Image widget by its modifiers such as size, shape, etc. We also can specify the Image object scaling algorithm, content description, etc. But how can we set a click event to an Image widget in a jetpack compose application? There is no built-in property/parameter/argument to set up an onClick event directly to the Image widget. This android application development tutorial will demonstrate to us how we can add a click event to the Image widget and make it clickable. Click event of a widget allow app users to execute a task such as showing a toast message by cli...
