How can you append lines to a file using StreamWriter without overwriting existing content?

Question

ICSM Computer · Answer

To append lines to a file using StreamWriter in C# without overwriting existing content, you need to pass
append: true to the constructor.
Example: Append Lines Using StreamWriter
using System.IO;
string filePath = "example.txt";
using (StreamWriter writer = new StreamWriter(filePath, append: true))
{
    writer.WriteLine("This is a new line being appended.");
    writer.WriteLine("Another appended line.");
}
Explanation:
append: true tells StreamWriter to open the file in append mode instead of overwriting it.If the file doesn't exist, it will be created automatically.
