C# Code Example: Using StringWriter with ISO-8859-1 Encoding

In C#, StringWriter is a class that allows you to write string data to a StringBuilder or a TextWriter object. By default, it uses the UTF-16 encoding for the output. However, you can specify a different encoding, such as ISO-8859-1, using the Encoding property.

Here's a code example that demonstrates how to use StringWriter with ISO-8859-1 encoding:

using System;
using System.IO;
using System.Text;

class Program
{
    static void Main(string[] args)
    {
        // Create a StringWriter object with ISO-8859-1 encoding
        StringWriter writer = new StringWriter(new StringBuilder(), Encoding.GetEncoding("iso-8859-1"));

        // Write some data to the StringWriter
        writer.WriteLine("This is some text in ISO-8859-1 encoding: \u00E9");

        // Display the output
        Console.WriteLine(writer.ToString());

        // Dispose the StringWriter object
        writer.Dispose();
    }
}

In this example, we first create a StringWriter object and specify the ISO-8859-1 encoding by using the Encoding.GetEncoding method.

We then write some text to the StringWriter that contains a special character (\u00E9) that is part of the ISO-8859-1 character set.

Finally, we display the output by converting the StringWriter object to a string using the ToString method and print it to the console.

Note that we also dispose the StringWriter object after we're done using it. This is important as it releases any underlying resources and helps prevent memory leaks.

Overall, using StringWriter with a specific encoding can be helpful when you need to write data in a specific format that requires a different encoding than the default UTF-16.
