For instance, if you have a list of medicaments formatted in fixed-width columns, you may only need to retrieve data from the first few columns. In this guide, we will walk you through how to effectively split a string by white spaces and manage this kind of data using C# . Understanding the Problem You have a file listing several medicaments. Each line contains data such as commercial names, doses, and forms, all stored in fixed-width columns. For example, a line from your file looks like this: [[See Video to Reveal this Text or Code Snippet]] From this, you want to retrieve just the first five columns, formatted as follows: [[See Video to Reveal this Text or Code Snippet]] Solution Breakdown To achieve this, we can utilize a fixed-width column reading approach in C# . Here’s how you can implement this solution step by step. Step 1: Setting Up Your Environment To begin, create a new C# console application. Use the following namespaces which will help us in managing files and data tables: [[See Video to Reveal this Text or Code Snippet]] Step 2: Define Fixed Width Ranges In your class, define the start positions of the columns you wish to extract. Each index in the array corresponds to a column's starting point in the string.
