C# for Bioinformatics: An Introduction

C# can be used for bioinformatics tasks, although languages like Python and R are more commonly used in this field. In this example, we'll demonstrate a basic DNA sequence analysis using C#.

Sample DNA Sequence Analysis Code

Here's a basic example of C# code to analyze a DNA sequence:

using System;
class Program
{
    static void Main()
    {
        string dnaSequence = "ATCGTAGCTAGCATCGATCG";
        int gcContent = CalculateGCContent(dnaSequence);
        Console.WriteLine("GC Content: " + gcContent + "%");
    }
    static int CalculateGCContent(string sequence)
    {
        int gcCount = 0;
        for (int i = 0; i < sequence.Length; i++)
        {
            char nucleotide = sequence[i];
            if (nucleotide == 'G' || nucleotide == 'C')
            {
                gcCount++;
            }
        }
        return (gcCount * 100) / sequence.Length;
    }
}
