c# 如何在字节数组中连续查找字节数组

在 C# 中如何在字节数组中进行连续查找

csharp
public class ByteArraySearch
{
    public static int FindByteArray(byte[] source, byte[] pattern)
    {
        if (source == null || pattern == null || source.Length == 0 || pattern.Length == 0 || pattern.Length > source.Length)
            return -1;
        for (int i = 0; i <= source.Length - pattern.Length; i++)
        {
            int j;
            for (j = 0; j < pattern.Length; j++)
            {
                if (source[i + j] != pattern[j])
                    break;
            }
            if (j == pattern.Length)
                return i; // 返回找到的位置索引
        }
        return -1; // 未找到
    }
}

csharp
class Program
{
    static void Main(string[] args)
    {
        byte[] sourceArray = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 };
        byte[] patternArray = { 3, 4, 5 };
        int foundIndex = ByteArraySearch.FindByteArray(sourceArray, patternArray);
        if (foundIndex != -1)
        {
            Console.WriteLine($"找到模式在源数组中的位置索引为：{foundIndex}");
        }
        else
        {
            Console.WriteLine("未找到匹配的模式！");
        }
    }
}
